- Abstract Advancements in computed tomography (CT) technology, particularly the emergence of dual-energy CT (DE-CT) and photon-counting detector CT (PCD-CT), can improve detection, characterization, and treatment monitoring of focal liver lesions. DE-CT, through its ability to differentiate tissues with similar densities and produce diverse datasets, has enhanced lesion visibility and diagnostic precision. PCD-CT further advances imaging with superior spatial resolution and material decomposition capabilities, offering potential for complex diagnostic scenarios. This review aimed to highlight the role of CT in hepatic imaging and its application to focal liver lesions. DE-CT improves lesion detectability using low-energy virtual monochromatic images, which enhance iodine contrast and reduce radiation and contrast agent doses. It also facilitates treatment response evaluation after locoregional therapies for hepatocellular carcinoma by quantifying biomarkers, such as the extracellular volume fraction. This review underscores the transformative impact of DE-CT and PCD-CT on liver imaging, emphasizing their complementary roles alongside magnetic resonance imaging. These innovations have paved the way for more precise diagnostics, improved treatment planning, and enhanced patient outcomes in the management of liver diseases.Ovid Technologies (Wolters Kluwer Health), Apr. 2025, Investigative RadiologyScientific journal

- Background/Objectives: Although immunotherapy is the primary treatment option for intermediate-stage hepatocellular carcinoma (HCC), its efficacy varies. This study aimed to identify non-invasive imaging biomarkers predictive of the immunoscore linked to dynamic contrast-enhanced computed tomography (CECT). Methods: We performed immunohistochemical staining with CD3+ and CD8+ antibodies and counted the positive cells in the invasive margin (IM) and central tumor (CT), converting them to an immunoscore of 0 to 4 points. We assessed the dynamic CECT findings obtained from 96 patients who underwent hepatectomy for HCC and evaluated the relationship between dynamic CECT findings and immunoscores. For validation, we assessed the treatment effects on 81 nodules using the Response Evaluation Criteria in Solid Tumors in another cohort of 41 patients who received combined immunotherapy with atezolizumab and bevacizumab (n = 27) and durvalumab and tremelizumab (n = 14). Results: HCCs with peritumoral enhancement in the arterial phase (p < 0.001) and rim APHE (p = 0.009) were associated with the immunoscore in univariate linear regression analysis and peritumoral enhancement in the arterial phase (p = 0.004) in multivariate linear regression analysis. The time to nodular progression in HCCs with peritumoral enhancement in the arterial phase was significantly longer than that in HCCs without this feature (p < 0.001). Conclusions: We identified HCCs with peritumoral enhancement in the arterial phase as a noninvasive imaging biomarker to predict immune-inflamed HCC with a high immunoscore tendency. These HCCs were most likely to respond to combined immunotherapy.Mar. 2025, Cancers, 17(6) (6), English, International magazineScientific journal
- Cine-magnetic resonance imaging (MRI) has been used to track respiratory-induced motion of the liver and tumor and assist in the accurate delineation of tumor volume. Recent developments in compressed sensitivity encoding (SENSE; CS) have accelerated temporal resolution while maintaining contrast resolution. This study aimed to develop and assess hepatobiliary phase (HBP) cine-MRI scans using CS. Phantom was imaged using cine-MRI and signal intensity (SI) and contrast ratio (CR) measured to determine the optimal flip-angle turbo field echo (TFE) prepulse delay. We performed cine-MRI in 20 patients for one minute, with images taken every 0.5 s after administration of gadoxetic acid contrast agent. Acquired images had three different acceleration factors (SENSE, CS without denoising [CS-no], and CS with strong denoising [CS-strong]). The image quality of the HBP cine MRI was quantitatively and qualitatively analyzed. In the phantom study, a flip angle of 30 °and TFE prepulse delay of 150 ms were optimal for clinical imaging. In a clinical study, CS-strong showed the highest signal-to-noise ratio and comparable contrast ratio among the three sequences. The CS-strong group showed a significantly higher image quality (P < 0.01), except for motion smoothness (P = 0.11). CS with denoising improved the tumor-to-liver contrast and image quality in high-temporal-resolution HBP cine MRI.Dec. 2024, Scientific reports, 14(1) (1), 31347 - 31347, English, International magazineScientific journal
- Introduction: Immunotherapy is the first-line treatment for intermediate-advanced stage hepatocellular carcinoma (HCC), although its outcomes vary. This study aimed to identify imaging biomarkers of immunotherapy susceptibility linked to gadoxetic acid-enhanced magnetic resonance imaging (EOB-MRI) and immune phenotypes, particularly immune-excluded phenotypes, with a tumor immune barrier.Methods: We performed immunohistochemical staining with a CD8+ antibody, and samples were classified into immune-inflamed, -intermediate, -excluded, and -ignored phenotypes. We assessed EOB-MRI findings obtained from 104 patients who underwent hepatectomy for HCC and evaluated the relationship between MRI findings and immune phenotype. Spatial transcriptome analysis of tumor tissues in each immune phenotype was performed to characterize the MRI findings. For validation, we analyzed the treatment effect on 60 nodules in another cohort of 27 patients who received combined immunotherapy using anti-programmed death-ligand 1 and anti-vascular endothelial growth factor (VEGF) antibodies.Results: HCCs with rim arterial phase hyperenhancement (APHE) (odds ratio [OR] 17.3 P=0.009), peritumoral enhancement on the arterial phase (OR 8.6, P<0.004), and intermediate intensity on the hepatobiliary phase (HBP) measured with a visual 3-point scale (OR 28.2, P=0.002) were associated with immune-excluded phenotype, where tumors tended to be larger and of the single nodular type with extranodular growth and confluent multinodular rather than the simple nodular type. Spatial transcriptome analysis revealed a spatial relationship among cytotoxic T lymphocytes, VEGF signals, and cancer-associated fibroblasts at the tumor-invasive margins in this phenotype. From the validation study, nodules with any one of these three imaging findings had a significantly prolonged time to-nodular progression (P=0.007, median not reached vs. 226 days).Conclusion: HCCs with rim APHE, peritumoral enhancement on arterial phase, and intermediate intensity on HBP with visual 3-point scale could be non-invasive biomarkers to predict the immune-excluded phenotype with tumor immune barrier. These HCCs were most likely to respond to the combined immunotherapy.S. Karger AG, Nov. 2024, Liver Cancer, 1 - 26Scientific journal
- BACKGROUND/OBJECTIVES: This study aimed to investigate the accuracy of Tumor, Node, Metastasis (TNM) classification based on radiology reports using GPT3.5-turbo (GPT3.5) and the utility of multilingual large language models (LLMs) in both Japanese and English. METHODS: Utilizing GPT3.5, we developed a system to automatically generate TNM classifications from chest computed tomography reports for lung cancer and evaluate its performance. We statistically analyzed the impact of providing full or partial TNM definitions in both languages using a generalized linear mixed model. RESULTS: The highest accuracy was attained with full TNM definitions and radiology reports in English (M = 94%, N = 80%, T = 47%, and TNM combined = 36%). Providing definitions for each of the T, N, and M factors statistically improved their respective accuracies (T: odds ratio [OR] = 2.35, p < 0.001; N: OR = 1.94, p < 0.01; M: OR = 2.50, p < 0.001). Japanese reports exhibited decreased N and M accuracies (N accuracy: OR = 0.74 and M accuracy: OR = 0.21). CONCLUSIONS: This study underscores the potential of multilingual LLMs for automatic TNM classification in radiology reports. Even without additional model training, performance improvements were evident with the provided TNM definitions, indicating LLMs' relevance in radiology contexts.Oct. 2024, Cancers, 16(21) (21), English, International magazineScientific journal

- PURPOSE: Flow-diverter (FD) stents were developed to treat aneurysms that are difficult to treat with conventional coiling or surgery. This study aimed to compare usefulness of Silent MRA and TOF (time of flight) -MRA in patients with aneurysms after FD placement. MATERIALS AND METHODS: We retrospectively collected images from 22 patients with 23 internal carotid artery aneurysms treated with FD. Two radiologists conducted MRA and DSA experiments. In the first reading experiment, the radiologists evaluated the aneurysm filling by employing Silent MRA and TOF-MRA and utilizing the modified O'Kelly-Marotta (OKM) scale, a four-class classification system for aneurysms after FD placement. We then calculated the agreement between the modified OKM scale on MRA and the original OKM scale on DSA. In the second reading experiment, the radiologists rated blood flow within the FD using a five-point scale. RESULTS: The weighted kappa value of the OKM scale between DSA and TOF-MRA was 0.436 (moderate agreement), and that between DSA and Silent MRA was 0.943 (almost perfect agreement). The accuracies for the four-class classification were 0.435 and 0.870 for TOF-MRA and Silent MRA, respectively. The mean score of blood flow within FD for TOF-MRA was 2.43 ± 0.90 and that for Silent MRA was 3.04 ± 1.02 (P < 0.001). CONCLUSION: Silent MRA showed a higher degree of agreement than TOF-MRA in aneurysm filling with DSA. In addition, Silent MRA was significantly superior to TOF-MRA in depicting blood flow within the FD. Therefore, Silent MRA is clinically useful for the follow-up of patients after FD placement.Aug. 2024, Japanese journal of radiology, English, Domestic magazineScientific journal
- PURPOSE: Minimal misregistration of fused PET and MRI images can be achieved with simultaneous positron emission tomography/magnetic resonance imaging (PET/MRI). However, the acquisition of multiple MRI sequences during a single PET emission scan may impair fusion precision of each sequence. This study evaluated the diagnostic utility of time-synchronized PET/MRI using an MR active trigger and a Bayesian penalized likelihood reconstruction algorithm (BPL) to assess the locoregional extension of endometrial cancer. METHODS: Fifty-five patients with endometrial cancer who underwent pelvic 2-deoxy-2-[18F]fluoro-D-glucose PET/MRI were retrospectively evaluated. The PET emission time for the BPL reconstruction was determined by the MR active trigger of each MR sequence. The concordance rates of image interpretation with pathological T-staging, diagnostic performance for deep myometrial invasion (MI), and diagnostic confidence levels were evaluated by two readers and compared between time-synchronized, overlapping (conventional and simultaneous, but not time-synchronized), and sequential (not simultaneous) PET/MRI and MRI with diffusion-weighted imaging. Misregistration of the PET/MRI-fused images was determined by evaluating the differences in bladder dimensions. RESULTS: The T classification by time-synchronized PET/MRI was the most concordant with the pathological T classification for the two readers. Time-synchronized PET/MRI had a significantly higher diagnostic performance for deep MI and higher confidence level scores than overlapping PET/MRI for the novice reader (p = 0.033 and p = 0.038, respectively). The differences in bladder dimension on sequential PET/MRI were significantly larger than those on overlapping and time-synchronized PET/MRI (p <0.001). CONCLUSION: Time-synchronized PET/MRI is superior to conventional PET/MRI for assessing the locoregional extension of endometrial cancer.Aug. 2024, European journal of radiology, 179, 111678 - 111678, English, International magazineScientific journal
- PURPOSE: To compare the image quality, inter-reader agreement, and diagnostic capability for muscle-invasive bladder cancer (MIBC) of the reconstructed images in sections orthogonal to the bladder tumor obtained by 3D Dynamic contrast-enhanced (DCE)-MRI using the Golden-angle Radial Sparse Parallel (GRASP) technique with the images directly captured using the Cartesian sampling. MATERIALS AND METHODS: This study involved 68 initial cases of bladder cancer examined with DCE-MRI (GRASP: n = 34, Cartesian: n = 34) at 3 Tesla. Four radiologists conducted qualitative evaluations (overall image quality, absence of motion artifact, absence of streak artifact, and tumor conspicuity) using a five-point Likert scale (5 = Excellent/None) and quantitative signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) measurements. The areas under the receiver-operating characteristic curves (AUCs) for the Vesical Imaging-Reporting and Data System (VI-RADS) DCE score for MIBC assessment were calculated. Inter-reader agreement was also assessed. RESULTS: GRASP notably enhanced overall image quality (pooled score: GRASP 4 vs. Cartesian 3, P < 0.0001), tumor conspicuity (5 vs. 3, P < 0.05), SNR (Median 38.2 vs. 19.0, P < 0.0001), and CNR (7.9 vs. 6.0, P = 0.005), with fewer motion artifacts (5 vs. 3, P < 0.0001) and minor streak artifacts (5 vs. 5, P > 0.05). Although no significant differences were observed, the GRASP group tended to have higher AUCs for MIBC (pooled AUCs: 0.92 vs. 0.88) and showed a trend toward higher inter-reader agreement (pooled kappa-value: 0.70 vs. 0.63) compared to the Cartesian group. CONCLUSIONS: Using the GRASP for 3D DCE-MRI, the reconstructed images in sections orthogonal to the bladder tumor achieved higher image quality and improve the clinical work flow, compared to the images directly captured using the Cartesian. GRASP tended to have higher diagnostic ability for MIBC and showed a trend toward higher inter-reader agreement compared to the Cartesian.Aug. 2024, Japanese journal of radiology, English, Domestic magazineScientific journal

- PURPOSE: To compare the utility of thin-slice fat-suppressed single-shot T2-weighted imaging (T2WI) with deep learning image reconstruction (DLIR) and conventional fast spin-echo T2WI with DLIR for evaluating pancreatic protocol. METHODS: This retrospective study included 42 patients (mean age, 70.2 years) with pancreatic cancer who underwent gadoxetic acid-enhanced MRI. Three fat-suppressed T2WI, including conventional fast-spin echo with 6 mm thickness (FSE 6 mm), single-shot fast-spin echo with 6 mm and 3 mm thickness (SSFSE 6 mm and SSFSE 3 mm), were acquired for each patient. For quantitative analysis, the SNRs of the upper abdominal organs were calculated between images with and without DLIR. The pancreas-to-lesion contrast on DLIR images was also calculated. For qualitative analysis, two abdominal radiologists independently scored the image quality on a 5-point scale in the FSE 6 mm, SSFSE 6 mm, and SSFSE 3 mm with DLIR. RESULTS: The SNRs significantly improved among the three T2-weighted images with DLIR compared to those without DLIR in all patients (P < 0.001). The pancreas-to-lesion contrast of SSFSE 3 mm was higher than those of the FSE 6 mm (P < 0.001) and tended to be higher than SSFSE 6 mm (P = 0.07). SSFSE 3 mm had the highest image qualities regarding pancreas edge sharpness, pancreatic duct clarity, and overall image quality, followed by SSFSE 6 mm and FSE 6 mm (P < 0.0001). CONCLUSION: SSFSE 3 mm with DLIR demonstrated significant improvements in SNRs of the pancreas, pancreas-to-lesion contrast, and image quality more efficiently than did SSFSE 6 mm and FSE 6 mm. Thin-slice fat-suppressed single-shot T2WI with DLIR can be easily implemented for pancreatic MR protocol.Jun. 2024, Magnetic resonance in medical sciences : MRMS : an official journal of Japan Society of Magnetic Resonance in Medicine, English, Domestic magazineScientific journal
- This study investigated the utility of imaging features, such as rim enhancement on contrast-enhanced CT (CECT), in predicting the prognosis of pancreatic ductal adenocarcinoma (PDAC). This retrospective study included 158 patients (84 men; mean age, 68 years) with pathologically confirmed PDAC. The following imaging features were evaluated on CECT by two radiologists: tumor size, tumor attenuation, and the presence of rim enhancement. Cox proportional hazards analysis was performed to identify the imaging and clinicopathological features for predicting disease-free survival (DFS) and overall survival (OS). Pathological features were compared with the presence of rim enhancement. Among the 158 patients, 106 (67%) underwent curative surgery (surgery group) and 52 (33%) received conservative treatment (non-surgery group). Rim enhancement was observed more frequently in the non-surgery group than in the surgery group (44% vs. 20%; p < 0.001). Rim enhancement showed significant associations with shorter DFS and OS in the surgery group (hazard ratios (HRs), 3.03 and 2.99; p < 0.001 and p = 0.003, respectively), whereas tumor size showed significant associations with shorter OS (HR per 1 mm increase, 1.08; p < 0.001). PDACs with rim enhancement showed significant associations with higher histological tumor grades (p < 0.001). PDAC with rim enhancement on CECT could predict poorer prognosis and more aggressive tumor grades.MDPI AG, Apr. 2024, Diagnostics, 14(8) (8), 782 - 782Scientific journal

- PURPOSE: The purpose of the study was to evaluate the efficacy and safety of pre-emptive transcatheter arterial embolization (P-TAE) of aortic side branches to prevent type II endoleak in patients with abdominal aortic aneurysm after endovascular abdominal aneurysm repair (EVAR). MATERIALS AND METHODS: This multicenter, prospective, single-arm trial enrolled 100 patients with abdominal aortic aneurysm from nine hospitals between 2018 and 2021. There were 85 men and 15 women, with a mean age of 79.6 ± 6.0 (standard deviation) years (range: 65-97 years). P-TAE was attempted for patent aortic side branches, including the inferior mesenteric artery, lumbar arteries, and other branches. The primary endpoint was late type II endoleak incidence at 6 months post-repair. Secondary endpoints included changes in aneurysmal sac diameter at 6- and 12 months, complications, re-intervention, and aneurysm-related mortality. Aneurysm sac changes at 6- and 12 months was compared between the late and no-late type II endoleak groups. RESULTS: Coil embolization was successful in 80.9% (321/397) of patent aortic side branches, including 86.3% of the inferior mesenteric arteries, 80.3% of lumbar arteries, and 55.6% of other branches without severe adverse events. Late type II endoleak incidence at 6 months was 8.9% (8/90; 95% confidence interval: 3.9-16.8%). Aneurysm sac shrinkage > 5 mm was observed in 41.1% (37/90) and 55.3% (47/85) of the patients at 6- and 12-months post-EVAR, respectively. Patients with late type II endoleak had less aneurysm sac shrinkage than those without type II endoleak at 12 months (-0.2 mm vs. -6.0 mm; P = 0.040). No patients required re-intervention for type II endoleak, and no aneurysm-related mortalities occurred. CONCLUSION: P-TAE is safe and effective in preventing type II endoleak, leading to early sac shrinkage at 12 months following EVAR.Mar. 2024, Diagnostic and interventional imaging, English, International magazineScientific journal
- PURPOSE: The occurrence of endoleaks, particularly type 2 endoleaks (EL2), is the primary cause of poor long-term prognosis after endovascular aneurysm repair (EVAR). This study aimed to evaluate the efficacy and safety of preemptive transcatheter arterial embolization (P-TAE) for aortic side branches (ASBs) to prevent EL2 before EVAR using the Excluder stent-graft system (EXCLUDER). MATERIALS AND METHODS: In this prospective, multicenter study, 80 patients (mean age, 79.1±6.7 years; 85.0% male patients; mean aneurysmal sac diameter, 48.4±7.4 mm) meeting the eligibility criteria were prospectively enrolled from nine hospitals. Before EVAR, p-TAE was performed to embolize the patent ASBs originating from the abdominal aortic aneurysm. Contrast-enhanced computed tomography was performed at 1 month and 6 months after EVAR. The primary endpoint was EL2 incidence at 6 months, and the secondary endpoints were aneurysmal sac diameter changes at 6 and 12 months, P-TAE outcomes, complications related to P-TAE, re-intervention, and aneurysm-related mortality. RESULTS: All patients successfully underwent P-TAE without serious complications. Coil embolization was successful in 81.6% of ASBs. EL2 incidence at 6 months was identified in 18/70 (25.7%) patients. Aneurysmal sac diameter shrinkage (≥5 mm) was observed in 30.0% of patients at 6 months and in 40.9% at 12 months. Only one patient required re-intervention for EL2 within 1 year of EVAR; aneurysm-related deaths were not observed. CONCLUSION: P-TAE for ASBs before EVAR using EXCLUDER is a safe and effective strategy. It aids in achieving early aneurysmal sac shrinkage and reduces EL2 re-intervention at 1 year after EVAR.Mar. 2024, Journal of vascular and interventional radiology : JVIR, English, International magazineScientific journal
- We report a case of a life-threatening ruptured renal angiomyolipoma (AML) that did not meet the criteria for prophylactic treatment (tumor >4 cm or intratumoral aneurysm >5 mm) during follow-up. A woman in her 70s was followed up for a 2.5-cm AML with a rich vascular component. An intratumoral aneurysm >5 mm was not identified for 2 years. She complained of a sudden abdominal pain with hypotension, and contrast-enhanced computed tomography revealed a retroperitoneal hematoma with contrast media extravasation from an intratumoral aneurysm. Emergency transcatheter arterial embolization was successfully performed using N-butyl cyanoacrylate glue. Rupture can occur in small AMLs or in AMLs not identified with intratumoral aneurysms during follow-up. AMLs with a rich vascular component at the kidney surface are more likely to rupture.Mar. 2024, Interventional radiology (Higashimatsuyama-shi (Japan), 9(1) (1), 20 - 25, English, Domestic magazine
- AIM: The IMbrave150 trial revealed that atezolizumab plus bevacizumab (AtezoBv) showed a higher objective response rate (ORR) in patients with advanced hepatocellular carcinoma (HCC). Although conversion therapy after AtezoBv has been recently reported, markers predictive of its efficacy, particularly radiological imaging markers, have not yet been identified. The present study focused on tumor morphological appearance on radiological imaging and evaluated whether it could be associated with AtezoBv efficacy. METHODS: Ninety-five intrahepatic lesions in 74 patients who were given AtezoBv for advanced HCC were recruited for evaluation. The lesions were divided into two groups, simple nodular (SN group) and non-simple nodular (non-SN group), based on the gross morphology on pretreatment imaging, and retrospectively evaluated for treatment response and other relevant clinical outcomes. RESULTS: Assessing the size of individual tumors after treatment, waterfall plots showed that tumor shrinkage in the non-SN group including 56 lesions was higher than that in the SN group comprising 39 lesions. The ORR was significantly higher in the non-SN group (39.3% vs. 15.4%, p = 0.012). Additionally, the median time to nodular progression was longer in the non-SN group (21.0 months vs. 8.1 months, p = 0.119) compared to the SN group. Six patients with non-SN lesions underwent sequential local therapy. CONCLUSIONS: Atezolizumab plus bevacizumab may show increased therapeutic efficacy in patients with tumors with a higher potential for aggressive oncological behavior, such as non-SN lesions. Treatment strategies focusing on conversion therapy may be crucial in patients with non-SN lesions.Feb. 2024, Hepatology research : the official journal of the Japan Society of Hepatology, English, International magazineScientific journal

- BACKGROUND AND PURPOSE: Mean pulmonary artery pressure (mPAP) is a key index for chronic thromboembolic pulmonary hypertension (CTEPH). Using machine learning, we attempted to construct an accurate prediction model for mPAP in patients with CTEPH. METHODS: A total of 136 patients diagnosed with CTEPH were included, for whom mPAP was measured. The following patient data were used as explanatory variables in the model: basic patient information (age and sex), blood tests (brain natriuretic peptide (BNP)), echocardiography (tricuspid valve pressure gradient (TRPG)), and chest radiography (cardiothoracic ratio (CTR), right second arc ratio, and presence of avascular area). Seven machine learning methods including linear regression were used for the multivariable prediction models. Additionally, prediction models were constructed using the AutoML software. Among the 136 patients, 2/3 and 1/3 were used as training and validation sets, respectively. The average of R squared was obtained from 10 different data splittings of the training and validation sets. RESULTS: The optimal machine learning model was linear regression (averaged R squared, 0.360). The optimal combination of explanatory variables with linear regression was age, BNP level, TRPG level, and CTR (averaged R squared, 0.388). The R squared of the optimal multivariable linear regression model was higher than that of the univariable linear regression model with only TRPG. CONCLUSION: We constructed a more accurate prediction model for mPAP in patients with CTEPH than a model of TRPG only. The prediction performance of our model was improved by selecting the optimal machine learning method and combination of explanatory variables.2024, PloS one, 19(4) (4), e0300716, English, International magazineScientific journal

- BACKGROUND: Deep learning (DL) has been widely used for diagnosis and prognosis prediction of numerous frequently occurring diseases. Generally, DL models require large datasets to perform accurate and reliable prognosis prediction and avoid overlearning. However, prognosis prediction of rare diseases is still limited owing to the small number of cases, resulting in small datasets. PURPOSE: This paper proposes a multimodal DL method to predict the prognosis of patients with malignant pleural mesothelioma (MPM) with a small number of 3D positron emission tomography-computed tomography (PET/CT) images and clinical data. METHODS: A 3D convolutional conditional variational autoencoder (3D-CCVAE), which adds a 3D-convolutional layer and conditional VAE to process 3D images, was used for dimensionality reduction of PET images. We developed a two-step model that performs dimensionality reduction using the 3D-CCVAE, which is resistant to overlearning. In the first step, clinical data were input to condition the model and perform dimensionality reduction of PET images, resulting in more efficient dimension reduction. In the second step, a subset of the dimensionally reduced features and clinical data were combined to predict 1-year survival of patients using the random forest classifier. To demonstrate the usefulness of the 3D-CCVAE, we created a model without the conditional mechanism (3D-CVAE), one without the variational mechanism (3D-CCAE), and one without an autoencoder (without AE), and compared their prediction results. We used PET images and clinical data of 520 patients with histologically proven MPM. The data were randomly split in a 2:1 ratio (train : test) and three-fold cross-validation was performed. The models were trained on the training set and evaluated based on the test set results. The area under the receiver operating characteristic curve (AUC) for all models was calculated using their 1-year survival predictions, and the results were compared. RESULTS: We obtained AUC values of 0.76 (95% confidence interval [CI], 0.72-0.80) for the 3D-CCVAE model, 0.72 (95% CI, 0.68-0.77) for the 3D-CVAE model, 0.70 (95% CI, 0.66-0.75) for the 3D-CCAE model, and 0.69 (95% CI 0.65-0.74) for the without AE model. The 3D-CCVAE model performed better than the other models (3D-CVAE, p = 0.039; 3D-CCAE, p = 0.0032; and without AE, p = 0.0011). CONCLUSIONS: This study demonstrates the usefulness of the 3D-CCVAE in multimodal DL models learned using a small number of datasets. Additionally, it shows that dimensionality reduction via AE can be used to learn a DL model without increasing the overlearning risk. Moreover, the VAE mechanism can overcome the uncertainty of the model parameters that commonly occurs for small datasets, thereby eliminating the risk of overlearning. Additionally, more efficient dimensionality reduction of PET images can be performed by providing clinical data as conditions and ignoring clinical data-related features.Dec. 2023, Medical physics, 50(12) (12), 7548 - 7557, English, International magazineScientific journal

- RATIONALE AND OBJECTIVES: Pericardial fat (PF)-the thoracic visceral fat surrounding the heart-promotes the development of coronary artery disease by inducing inflammation of the coronary arteries. To evaluate PF, we generated pericardial fat count images (PFCIs) from chest radiographs (CXRs) using a dedicated deep-learning model. MATERIALS AND METHODS: We reviewed data of 269 consecutive patients who underwent coronary computed tomography (CT). We excluded patients with metal implants, pleural effusion, history of thoracic surgery, or malignancy. Thus, the data of 191 patients were used. We generated PFCIs from the projection of three-dimensional CT images, wherein fat accumulation was represented by a high pixel value. Three different deep-learning models, including CycleGAN were combined in the proposed method to generate PFCIs from CXRs. A single CycleGAN-based model was used to generate PFCIs from CXRs for comparison with the proposed method. To evaluate the image quality of the generated PFCIs, structural similarity index measure (SSIM), mean squared error (MSE), and mean absolute error (MAE) of (i) the PFCI generated using the proposed method and (ii) the PFCI generated using the single model were compared. RESULTS: The mean SSIM, MSE, and MAE were 8.56 × 10-1, 1.28 × 10-2, and 3.57 × 10-2, respectively, for the proposed model, and 7.62 × 10-1, 1.98 × 10-2, and 5.04 × 10-2, respectively, for the single CycleGAN-based model. CONCLUSION: PFCIs generated from CXRs with the proposed model showed better performance than those generated with the single model. The evaluation of PF without CT may be possible using the proposed method.Oct. 2023, Academic radiology, English, International magazineScientific journal
- To evaluate the diagnostic performance of our deep learning (DL) model of COVID-19 and investigate whether the diagnostic performance of radiologists was improved by referring to our model. Our datasets contained chest X-rays (CXRs) for the following three categories: normal (NORMAL), non-COVID-19 pneumonia (PNEUMONIA), and COVID-19 pneumonia (COVID). We used two public datasets and private dataset collected from eight hospitals for the development and external validation of our DL model (26,393 CXRs). Eight radiologists performed two reading sessions: one session was performed with reference to CXRs only, and the other was performed with reference to both CXRs and the results of the DL model. The evaluation metrics for the reading session were accuracy, sensitivity, specificity, and area under the curve (AUC). The accuracy of our DL model was 0.733, and that of the eight radiologists without DL was 0.696 ± 0.031. There was a significant difference in AUC between the radiologists with and without DL for COVID versus NORMAL or PNEUMONIA (p = 0.0038). Our DL model alone showed better diagnostic performance than that of most radiologists. In addition, our model significantly improved the diagnostic performance of radiologists for COVID versus NORMAL or PNEUMONIA.Oct. 2023, Scientific reports, 13(1) (1), 17533 - 17533, English, International magazineScientific journal

- To develop and investigate the feasibility of sub-second temporal resolution volumetric T1-weighted four-dimensional (4D-) MRI in comparison with 4D-CT for respiratory-correlated motion assessment using an MRI/CT-compatible phantom. Sub-second high temporal resolution (0.5 s) gradient-echo T1-weighted 4D-MRI was developed using a volumetric acquisition scheme with compressed sensing. An MRI/CT-compatible motion phantom (simulated liver tumor) with three sinusoidal movements of amplitudes and two respiratory patterns was introduced and imaged with 4D-MRI and 4D-CT to investigate the geometric accuracy of the target movement. The geometric accuracy, including centroid position, volume, similarity index of dice similarity coefficient (DSC), and Hausdorff distance (HD), was systematically evaluated. Proposed 4D-MRI achieved a similar geometric accuracy compared with 4D-CT regarding the centroid position, volume, and similarity index. The observed position differences of the absolute average centroid were within 0.08 cm in 4D-MRI and 0.03 cm in 4D-CT, less than the 1-pixel resolution for each modality. The observed volume difference in 4D-MRI/4D-CT was within 0.73 cm3 (4.5%)/0.29 cm3 (2.1%) for a large target and 0.06 cm3 (11.3%)/0.04 cm3 (11.6%) for a small target. The observed DSC values for 4D-MRI/4D-CT were at least 0.93/0.95 for the large target and 0.83/0.84 for the small target. The maximum HD values were 0.25 cm/0.31 cm for the large target and 0.21 cm/0.15 cm for the small target. Although 4D-CT potentially exhibit superior numerical accuracy in phantom studies, the proposed high temporal resolution 4D-MRI demonstrates sub-millimetre geometric accuracy comparable to that of 4D-CT. These findings suggest that the 4D-MRI technique is a viable option for characterizing motion and generating phase-dependent internal target volumes within the realm of radiotherapy.Sep. 2023, Scientific reports, 13(1) (1), 15685 - 15685, English, International magazineScientific journal
- AIM: To determine risk factors associated with hepatocellular carcinoma (HCC) development following direct-acting antiviral (DAA) therapy. METHODS: We enrolled patients with chronic hepatitis C who underwent direct-acting antiviral therapy and achieved sustained virologic response at 12 weeks between 2012 and 2018. Subsequently, patients were followed up. The primary endpoint was the development of HCC or the date of the last follow up when the absence of HCC was confirmed. Uni- and multivariate Cox proportional hazards models were used to identify factors contributing to HCC development, including gadoxetic acid-enhanced magnetic resonance imaging findings. The cumulative incidence rates of HCC development were calculated using the Kaplan-Meier method, and differences between groups were assessed using the log-rank test. RESULTS: The final study cohort comprised 482 patients (median age 70.5 years; 242 men). The median follow-up period was 36.8 months. Among 482 patients, 96 developed HCC (19.9%). The 1-, 3-, and 5-year cumulative rates of HCC development were 4.9%, 18.6%, and 30.5%, respectively. Multivariate analysis revealed that age, male sex, history of HCC, and hepatobiliary phase hypointense nodules without arterial phase hyperenhancement were independent risk factors significantly associated with HCC development (p < 0.001-0.04). The highest risk group included patients with both a history of HCC and the presence of hepatobiliary phase hypointense nodules without arterial phase hyperenhancement (the 1- and 3-year cumulative HCC development rates were 14.2% and 62.2%, respectively). CONCLUSION: History of HCC and presence of hepatobiliary phase hypointense nodules without arterial phase hyperenhancement were strong risk factors for HCC development following direct-acting antiviral therapy.Sep. 2023, Hepatology research : the official journal of the Japan Society of Hepatology, English, International magazineScientific journal
- Abstract Objectives To ascertain the clinical behaviors of unclassified renal cell carcinoma (RCC) and its characteristic imaging findings on CT and MRI. Methods Subjects in this retrospective study were 10 patients who had received a histological diagnosis of unclassified RCC based on World Health Organization (WHO) 2022 and who had undergone CT and/or MRI prior to surgery. In terms of clinical behaviors, TNM classification, stage, postoperative recurrence, time to recurrence, and postoperative survival were evaluated. In terms of imaging findings, tumor size, growth pattern, CT density, dynamic contrast-enhancement (DCE) pattern, internal appearance, presence of a pseudocapsule, and signal intensity on MRI were evaluated. We compared clinical behaviors and imaging findings, and investigated associations between them. Results One patient could not be followed-up due to death from other causes. Postoperative recurrence was observed in 4 patients, all of whom had Stage 3 RCC. In the remaining 5 patients without recurrence, all 5 patients showed Stage 2 or below. On imaging, unclassified RCC tended to be large (58.7 mm) and solid (100%), and heterogeneous interiors (80%), cystic degeneration (80%) and high intensity on diffusion-weighted imaging (DWI) (71.4%) were common. Comparing patients with and without recurrence, the following findings tended to differ between recurrence and recurrence-free groups: tumor size (73.4 ± 33.9 mm vs. 50.2 ± 33.9 mm, P = 0.286), growth pattern (invasive: 100% vs. 0%, expansive: 0% vs. 100%, P = 0.008 each), DCE pattern (progressive enhancement pattern, 66.7% vs. 0%, washout pattern, 0% vs. 66.7%, P = 0.135 each) and presence of a pseudocapsule (25% vs. 80%, P = 0.167). Conclusion The clinical behavior of unclassified RCC varies widely. Although imaging findings are also variable, findings of large, heterogeneous tumors with cystic degeneration and high intensity on DWI were common. Several imaging findings such as large size, invasive growth, progressive enhancement pattern and no pseudocapsule may enable prediction of prognosis in unclassified RCC.Springer Science and Business Media LLC, Aug. 2023, Japanese Journal of RadiologyScientific journal
- In the 23rd Nationwide Follow-up Survey of Primary Liver Cancer in Japan, data from 20,889 newly registered patients and 42,274 previously registered follow-up patients were compiled from 516 institutions over a 2-year period from 1 January 2014 to 31 December 2015. Basic statistics compiled for patients newly registered in the 23rd survey was cause of death, past medical history, clinical diagnosis, imaging diagnosis, treatment-related factors, pathological diagnosis, recurrence status, and autopsy findings. Compared with the previous 22nd survey, the population of patients with hepatocellular carcinoma (HCC) was older at the time of clinical diagnosis, had more female patients, had more patients with non-B non-C HCC, had smaller tumor diameter, and was more frequently treated with hepatectomy. Cumulative survival rates were calculated for HCC, intrahepatic cholangiocarcinoma (ICC), and combined hepatocellular cholangiocarcinoma (combined HCC and ICC) by treatment type and background characteristics for patients newly registered between 2004 and 2015 whose final outcome was survival or death. Median overall survival and cumulative survival rates for HCC were calculated by dividing patients by combinations of background factors (number of tumors, tumor diameter, Child-Pugh grade, or ALBI grade) and by treatment type (hepatectomy, radiofrequency ablation therapy [RFA], transcatheter arterial chemoembolization [TACE], hepatic arterial infusion chemotherapy [HAIC] and systemic therapy). The same values were also calculated according to registration date by dividing patients newly registered between 1978 and 2015 into five time period groups. The data obtained from this nationwide follow-up survey are expected to contribute to advancing clinical research and treatment of primary liver cancer in the world.

- PURPOSE: This study aimed to investigate the impact of transarterial embolization (TAE) on macrophage polarization and the modulatory effect of lenvatinib in combination with TAE in a rat hepatocellular carcinoma model. MATERIALS AND METHODS: A rat N1S1-bearing orthotopic model was subjected to TAE and administered 5 mg/kg of lenvatinib. CD8+, CD68+, and CD206+ cells were examined in four cohorts: sham (n=5), lenvatinib (n=5), TAE (n=5), and a combination of TAE and lenvatinib (n=5). Transcriptome analysis was performed to assess gene expression related to macrophage polarization in the sham, TAE, and combination groups. An in vitro co-culture experiment with bone marrow-derived macrophages was performed to identify lenvatinib target in macrophage polarization. RESULTS: There were no significant differences in the number of CD8+ and CD68+ cells among the four groups. Tumor-associated macrophage positivity for CD206 was significantly higher in the TAE group (58.1 ± 20.9) than in the sham (11.2 ± 14.3, P < 0.001) and combination (27.1 ± 19.7, P = 0.003) groups. In the transcriptome analysis, compared with those in the sham group, five macrophage polarization-related genes, including St6gal1, were upregulated by more than 1.5-fold in the TAE group and downregulated by more than 1.5-fold in the combination group. The co-culture experiment showed that lenvatinib did not affect macrophages but N1S1 cells, leading to macrophage polarization. CONCLUSION: TAE induced M2 macrophage polarization. Lenvatinib administration with TAE could reprogram macrophage polarization, improving tumor immune microenvironment.Jul. 2023, Journal of vascular and interventional radiology : JVIR, English, International magazineScientific journal

The manuscript also includes a panel discussion by multidisciplinary experts on three selected cases that explore challenging aspects of HCC management. CLINICAL RELEVANCE STATEMENT: This review highlights the importance of a multidisciplinary team approach in liver cancer patients and includes the perspectives of a liver surgeon, an interventional radiologist, and an oncologist, including illustrative case studies. KEY POINTS: • A liver surgeon, interventional radiologist, and oncologist presented their perspectives on the treatment of early-, mid-, and late-stage HCC. • Different perspectives on HCC management between specialties emphasize the importance of multidisciplinary tumor boards. • A multidisciplinary faculty discussed challenging aspects of HCC management, as highlighted by three case studies.Jul. 2023, European radiology, English, International magazineScientific journal
- Metastatic rectal cancer is rare and difficult to differentiate from primary rectal cancer. A 79-year-old man with a rectal mass detected by CT during postoperative follow-up of gastric cancer underwent 18F-FDG PET/MRI. Fused PET/MRI images revealed a lower FDG uptake within the mass, which appeared to surround the outside of the rectum, than in the rectal wall, suggesting rectal dissemination of gastric cancer. PET/MRI was useful for differentiating between mass and rectal wall uptake, because of the high contrast resolution of MRI and precise image fusion made possible by simultaneous image acquisition.Jul. 2023, Clinical nuclear medicine, English, International magazineScientific journal
- This study evaluated the diagnostic value of a rapid whole-body fluorodeoxyglucose (FDG) positron emission tomography (PET)/magnetic resonance imaging (MRI) approach, combining Bayesian penalised likelihood (BPL) PET with an optimised β value and abbreviated MRI (abb-MRI). The study compares the diagnostic performance of this approach with the standard PET/MRI that utilises ordered subsets expectation maximisation (OSEM) PET and standard MRI (std-MRI). The optimal β value was determined by evaluating the noise-equivalent count (NEC) phantom, background variability, contrast recovery, recovery coefficient, and visual scores (VS) for OSEM and BPL with β100–1000 at 2.5-, 1.5-, and 1.0-min scans, respectively. Clinical evaluations were conducted for NECpatient, NECdensity, liver signal-to-noise ratio (SNR), lesion maximum standardised uptake value, lesion signal-to-background ratio, lesion SNR, and VS in 49 patients. The diagnostic performance of BPL/abb-MRI was retrospectively assessed for lesion detection and differentiation in 156 patients using VS. The optimal β values were β600 for a 1.5-min scan and β700 for a 1.0-min scan. BPL/abb-MRI at these β values was equivalent to OSEM/std-MRI for a 2.5-min scan. By combining BPL with optimal β and abb-MRI, rapid whole-body PET/MRI could be achieved in ≤1.5 min per bed position, while maintaining comparable diagnostic performance to standard PET/MRI.MDPI AG, May 2023, Diagnostics, 13(11) (11), 1871 - 1871, EnglishScientific journal
- Coronavirus disease (COVID-19) vaccination is known to cause a diagnostic dilemma due to false-positive findings on [18F]FDG PET in vaccine-associated hypermetabolic lymphadenopathy. We present two case reports of women with estrogen-receptor (ER)-positive cancer of the breast who were vaccinated for COVID-19 in the deltoid muscle. [18F]FDG positron emission tomography (PET) demonstrated primary breast cancer and multiple axillary lymph nodes with increased [18F]FDG uptake, diagnosed as vaccine-associated [18F]FDG-avid lymph nodes. Subsequent [18F]FES PET revealed single axillary lymph node metastasis in the vaccine-associated [18F]FDG-avid lymph nodes. To the best of our knowledge, this is the first study showing the usefulness of [18F]FES PET in diagnosing axillary lymph node metastasis in COVID-19-vaccinated patients harboring ER-positive breast cancer. Thus, [18F]FES PET has potential applications in the detection of true-positive metastatic lymph nodes in patients with ER-positive breast cancer regardless of the ipsilateral or contralateral side, who have received COVID-19 vaccination.May 2023, Diagnostics (Basel, Switzerland), 13(11) (11), English, International magazine

- To assess the value of nonenhancing capsule by adding to enhancing capsule in gadoxetic acid-enhanced MRI (EOB-MRI) in comparison with contrast-enhanced CT (CE-CT) for diagnosing histological capsule in hepatocellular carcinoma (HCC). One-hundred fifty-one patients with HCC who underwent both CE-CT and EOB-MRI were retrospectively reviewed. Liver Imaging-Reporting and Data System (LI-RADS) v2018 imaging features, including enhancing and nonenhancing capsule were evaluated by two readers in CE-CT and EOB-MRI. Frequencies of each imaging feature were compared between CE-CT and EOB-MRI. The area under the receiver operating characteristic (AUC) curve for the diagnosis of histological capsule was compared across the following three imaging criteria: (1) enhancing capsule in CE-CT, (2) enhancing capsule in EOB-MRI, and (3) enhancing/nonenhancing capsule in EOB-MRI. Enhancing capsule in EOB-MRI was significantly less frequently depicted than that in CE-CT (p < 0.001 and = 0.016 for reader 1 and 2). Enhancing/nonenhancing capsule in EOB-MRI achieved a similar frequency of enhancing in CE-CT (p = 0.590 and 0.465 for reader 1 and 2). Adding nonenhancing capsule to enhancing capsule in EOB-MRI significantly increased AUCs (p < 0.001 for both readers) and achieved similar AUCs compared with enhancing capsule in CE-CT (p = 0.470 and 0.666 for reader 1 and 2). Adding nonenhancing capsule to the definition of capsule appearance can improve the diagnosis of capsule in EOB-MRI for the diagnosis of histological capsule in HCC and decrease discordance of capsule appearance between EOB-MRI and CE-CT.Apr. 2023, Scientific reports, 13(1) (1), 6113 - 6113, English, International magazineScientific journal

- The incidence of hepatocellular carcinoma (HCC) is still on the rise in North America and Europe and is the second leading cause of cancer-related mortality. The treatment of HCC varies, with surgery and locoregional therapy (LRT) such as radiofrequency ablation and transcatheter arterial chemoembolization, and radiation therapy being the primary treatment. Currently, systemic therapy with molecular-targeted agents and immune checkpoint inhibitors (ICIs) is becoming a major treatment option for the unresectable HCC. As the HCC after LRT or systemic therapy often remains unchanged in size and shows loss of contrast effect in contrast-enhanced CT or MRI, the response evaluation criteria in solid tumors (RECIST) and World Health Organization criteria, which are usually used to evaluate the treatment response of solid tumors, are not appropriate for HCC. The modified RECIST (mRECIST) and the European Association for the Study of the Liver (EASL) criteria were developed for HCC, with a focus on viable lesions. The latest 2018 edition of the Liver Imaging Reporting and Data System (LI-RADS) also includes a section on the evaluation of treatment response. The cancer microenvironment influences the therapeutic efficacy of ICIs. Several studies have examined the utility of gadoxetic acid-enhanced MRI for predicting the pathological and molecular genetic patterns of HCC. In the future, it may be possible to stratify prognosis and predict treatment response prior to systemic therapy by using pre-treatment imaging findings.Japanese Society for Magnetic Resonance in Medicine, Apr. 2023, Magnetic resonance in medical sciences : MRMS : an official journal of Japan Society of Magnetic Resonance in Medicine, 22(2) (2), 209 - 220, English, Domestic magazine[Refereed]Scientific journal

- PURPOSE: To investigate the added value of contrast enhancement boost (CE-boost) images in multiphasic contrast-enhanced CT (CE-CT) for diagnosing small (<20 mm) hypervascular hepatocellular carcinoma (HCC). MATERIALS AND METHODS: This retrospective study included 69 patients (age, 74 ± 8 years; 52 men) with 70 hypervascular HCCs (<20 mm) who underwent multiphasic CE-CT (pre-contrast, late arterial phase [LAP], portal venous phase [PVP], and equilibrium phase). Two types of CE-boost images were generated by subtracting PVP from LAP (LA-PV) images and LAP from PVP (PV-LA) images to enhance the contrast effect of hepatic arterial and portal venous perfusion more selectively. Tumor-to-liver contrast-to-noise ratios (CNRs) in CE-boost images were compared with those in CE-CT images using the Wilcoxon signed-rank test. Two independent readers reviewed the imaging datasets: CE-CT alone and CE-CT with CE-boost images. The diagnostic performance of each dataset was compared using jackknife alternative free-response receiver operating characteristics (JAFROC-1). RESULTS: The tumor-to-liver CNRs in the LA-PV (6.4 ± 3.0) and PV-LA (-3.3 ± 2.1) images were greater than those in the LAP (3.2 ± 1.7) and PVP images (-1.1 ± 1.4) (p <.001 for both). The reader-averaged figures of merit were 0.751 for CE-CT alone and 0.807 for CE-CT with CE-boost images (p <.001). Sensitivities increased by adding CE-boost images for both readers (p <.001 and = 0.03), while positive predictive values were equivalent (p >.99). CONCLUSION: Adding CE-boost images to multiphasic CE-CT can improve the diagnostic accuracy and sensitivity for small hypervascular HCC by increasing the tumor-to-liver CNR.Last, Elsevier BV, Mar. 2023, European journal of radiology, 160, 110696 - 110696, English, International magazine[Refereed]Scientific journal

- 510 Background: Currently 6 regimens are available for advanced hepatocellular carcinoma (HCC) in Japan, including atezolizumab plus bevacizumab (AB), sorafenib (S), and lenvatinib (L) for first-line treatment and regorafenib (R), ramucirumab (RAM), and cabozantinib (C) for the second-line treatment. In real-world clinical practice, the number of combinations of treatment sequences is enormous. We have launched a nationwide registry of systemic therapy for HCC named Hepatoma Registry of Integrating and Aggregating Electric Health Records (HERITAGE). Methods: The HERITAGE is linked to the nationwide follow-up survey of the Japan Liver Cancer Association; cases treated with systemic therapy between 2015 and 2022 were included in the current study. Information on treatment efficacy and duration was collected and registered on each treatment regimen. Results: As of June 2022, 6,400 treatment lines (S 2,319, L 2559, AB 768, R 406, RAM 251, C 71) in 4,307 cases were enrolled. The response rates, disease control rates, and median treatment duration of each sequence of regimens are shown in the table. The 1st line regimen, S, L, and AB, were also used as the second and later lines in Japan and found as effective as if used as the 1st line treatment. Limitation: No adjustments for clinical conditions were performed. Conclusions: We have demonstrated the efficacy of various treatment sequences in a sufficient number of cases.

- OBJECTIVES: To investigate the effect of deep learning image reconstruction (DLIR) on the accuracy of iodine quantification and image quality of dual-energy CT (DECT) compared to that of other reconstruction algorithms in a phantom experiment and an abdominal clinical study. METHODS: An elliptical phantom with five different iodine concentrations (1-12 mgI/mL) was imaged five times with fast-kilovoltage-switching DECT for three target volume CT dose indexes. All images were reconstructed using filtered back-projection, iterative reconstruction (two levels), and DLIR algorithms. Measured and nominal iodine concentrations were compared among the algorithms. Contrast-enhanced CT of the abdomen with the same scanner was acquired in clinical patients. In arterial and portal venous phase images, iodine concentration, image noise, and coefficients of variation for four locations were retrospectively compared among the algorithms. One-way repeated-measures analyses of variance were used to evaluate differences in the iodine concentrations, standard deviations, coefficients of variation, and percentages of error among the algorithms. RESULTS: In the phantom study, the measured iodine concentrations were equivalent among the algorithms: within ± 8% of the nominal values, with root-mean-square deviations of 0.08-0.36 mgI/mL, regardless of radiation dose. In the clinical study (50 patients; 35 men; mean age, 68 ± 11 years), iodine concentrations were equivalent among the algorithms for each location (all p > .99). Image noise and coefficients of variation were lower with DLIR than with the other algorithms (all p < .01). CONCLUSIONS: The DLIR algorithm reduced image noise and variability of iodine concentration values compared with other reconstruction algorithms in the fast-kilovoltage-switching dual-energy CT. KEY POINTS: • In the phantom study, standard deviations and coefficients of variation in iodine quantification were lower on images with the deep learning image reconstruction algorithm than on those with other algorithms. • In the clinical study, iodine concentrations of measurement location in the upper abdomen were consistent across four reconstruction algorithms, while image noise and variability of iodine concentrations were lower on images with the deep learning image reconstruction algorithm.Springer Science and Business Media LLC, Feb. 2023, European radiology, 33(2) (2), 1388 - 1399, English, International magazineScientific journal

- PURPOSE: The purpose of this study is to compare two libraries dedicated to the Markov chain Monte Carlo method: pystan and numpyro. In the comparison, we mainly focused on the agreement of estimated latent parameters and the performance of sampling using the Markov chain Monte Carlo method in Bayesian item response theory (IRT). MATERIALS AND METHODS: Bayesian 1PL-IRT and 2PL-IRT were implemented with pystan and numpyro. Then, the Bayesian 1PL-IRT and 2PL-IRT were applied to two types of medical data obtained from a published article. The same prior distributions of latent parameters were used in both pystan and numpyro. Estimation results of latent parameters of 1PL-IRT and 2PL-IRT were compared between pystan and numpyro. Additionally, the computational cost of the Markov chain Monte Carlo method was compared between the two libraries. To evaluate the computational cost of IRT models, simulation data were generated from the medical data and numpyro. RESULTS: For all the combinations of IRT types (1PL-IRT or 2PL-IRT) and medical data types, the mean and standard deviation of the estimated latent parameters were in good agreement between pystan and numpyro. In most cases, the sampling time using the Markov chain Monte Carlo method was shorter in numpyro than that in pystan. When the large-sized simulation data were used, numpyro with a graphics processing unit was useful for reducing the sampling time. CONCLUSION: Numpyro and pystan were useful for applying the Bayesian 1PL-IRT and 2PL-IRT. Our results show that the two libraries yielded similar estimation result and that regarding to sampling time, the fastest libraries differed based on the dataset size.2023, PeerJ.

- PURPOSE: This study proposes a Bayesian multidimensional nominal response model (MD-NRM) to statistically analyze the nominal response of multiclass classifications. MATERIALS AND METHODS: First, for MD-NRM, we extended the conventional nominal response model to achieve stable convergence of the Bayesian nominal response model and utilized multidimensional ability parameters. We then applied MD-NRM to a 3-class classification problem, where radiologists visually evaluated chest X-ray images and selected their diagnosis from one of the three classes. The classification problem consisted of 150 cases, and each of the six radiologists selected their diagnosis based on a visual evaluation of the images. Consequently, 900 (= 150 × 6) nominal responses were obtained. In MD-NRM, we assumed that the responses were determined by the softmax function, the ability of radiologists, and the difficulty of images. In addition, we assumed that the multidimensional ability of one radiologist were represented by a 3 × 3 matrix. The latent parameters of the MD-NRM (ability parameters of radiologists and difficulty parameters of images) were estimated from the 900 responses. To implement Bayesian MD-NRM and estimate the latent parameters, a probabilistic programming language (Stan, version 2.21.0) was used. RESULTS: For all parameters, the Rhat values were less than 1.10. This indicates that the latent parameters of the MD-NRM converged successfully. CONCLUSION: The results show that it is possible to estimate the latent parameters (ability and difficulty parameters) of the MD-NRM using Stan. Our code for the implementation of the MD-NRM is available as open source.Dec. 2022, Japanese journal of radiology, 41(4) (4), 449 - 455, English, Domestic magazineScientific journal

- AIM: Although Makuuchi's criteria are widely used to determine the cut-off for safe liver resection, there have been few reports of concrete data supporting their validity. Here, we verified the utility of Makuuchi's criteria by comparing the operative mortality rates associated with liver resection between hepatocellular carcinoma (HCC) patients meeting or exceeding the criteria. METHODS: A database was built using data from 15 597 patients treated between 2000 and 2007 for whom values for all three variables included in Makuuchi's criteria for liver resection (clinical ascites, serum bilirubin, and indocyanine green clearance) were available. The patients were divided into those fulfilling (n = 12 175) or exceeding (n = 3422) the criteria. The postoperative mortality (death for any reason within 30 days) and long-term survival were compared between the two groups. RESULTS: The operative mortality rate was significantly lower in patients meeting the criteria than in those exceeding the criteria (1.07% vs. 2.01%, respectively; p < 0.001). On multivariate analysis, exceeded the criteria was significantly associated with the risk for operative mortality (relative risk 2.08; 95% confidence interval (CI), 1.23-3.52; p = 0.007). Surgical indication meeting or exceeding the criteria was an independent factor for overall survival (hazard ratio 1.27; 95% CI, 1.18-1.36; p < 0.001). CONCLUSION: Makuuchi's criteria are suitable for determining the indication for resection of HCC due to the reduction in risk of operative mortality.Wiley, Oct. 2022, Hepatology research : the official journal of the Japan Society of Hepatology, 53(2) (2), 127 - 134, English, International magazineScientific journal
- Abstract Background Spinal fractures rarely cause hemothorax, and no treatment consensus has been reached. Conservative treatment is generally selected in cases without arterial injury, but there have been some reports of uncontrolled bleeding. Here we report a case of hemothorax caused by spinal fracture without arterial injury treated with transcatheter arterial embolization. Case presentation An 88-year-old Japanese woman with back pain was diagnosed with hemothorax due to bleeding from an unstable fracture of the tenth thoracic vertebra. Contrast-enhanced computed tomography revealed no obvious arterial injury. We performed transcatheter arterial embolization of the bilateral tenth intercostal arteries to prevent rebleeding. The hemothorax did not worsen until surgical spinal fixation 9 days post-transcatheter arterial embolization, and she was discharged 30 days after admission. Conclusion Transcatheter arterial embolization for hemothorax caused by spinal fractures without obvious arterial injury may be a useful bridge to spinal fixation.Springer Science and Business Media LLC, Sep. 2022, Journal of Medical Case Reports, 16(1) (1)Scientific journal

- This paper presents the first version of clinical practice guidelines for intrahepatic cholangiocarcinoma (ICC) established by the Liver Cancer Study Group of Japan. These guidelines consist of 1 treatment algorithm, 5 background statements, 16 clinical questions, and 1 clinical topic, including etiology, staging, pathology, diagnosis, and treatments. Globally, a high incidence of ICC has been reported in East and Southeast Asian countries, and the incidence has been gradually increasing in Japan and also in Western countries. Reported risk factors for ICC include cirrhosis, hepatitis B/C, alcohol consumption, diabetes, obesity, smoking, nonalcoholic steatohepatitis, and liver fluke infestation, as well as biliary diseases, such as primary sclerosing cholangitis, hepatolithiasis, congenital cholangiectasis, and Caroli disease. Chemical risk factors include thorium-232, 1,2-dichloropropane, and dichloromethane. CA19-9 and CEA are recommended as tumor markers for early detection and diagnostic of ICC. Abdominal ultrasonography, CT, and MRI are effective imaging modalities for diagnosing ICC. If bile duct invasion is suspected, imaging modalities for examining the bile ducts may be useful. In unresectable cases, tumor biopsy should be considered when deemed necessary for the differential diagnosis and drug therapy selection. The mainstay of treatment for patients with Child-Pugh class A or B liver function is surgical resection and drug therapy. If the patient has no regional lymph node metastasis (LNM) and has a single tumor, resection is the treatment of choice. If both regional LNM and multiple tumors are present, drug therapy is the first treatment of choice. If the patient has either regional LNM or multiple tumors, resection or drug therapy is selected, depending on the extent of metastasis or the number of tumors. If distant metastasis is present, drug therapy is the treatment of choice. Percutaneous ablation therapy may be considered for patients who are ineligible for surgical resection or drug therapy due to decreased hepatic functional reserve or comorbidities. For unresectable ICC without extrahepatic metastasis, stereotactic radiotherapy (tumor size ≤5 cm) or particle radiotherapy (no size restriction) may be considered. ICC is generally not indicated for liver transplantation, and palliative care is recommended for patients with Child-Pugh class C liver function.S.

- The integrated positron emission tomography/magnetic resonance imaging (PET/MRI) scanner simultaneously acquires metabolic information via PET and morphological information using MRI. However, attenuation correction, which is necessary for quantitative PET evaluation, is difficult as it requires the generation of attenuation-correction maps from MRI, which has no direct relationship with the gamma-ray attenuation information. MRI-based bone tissue segmentation is potentially available for attenuation correction in relatively rigid and fixed organs such as the head and pelvis regions. However, this is challenging for the chest region because of respiratory and cardiac motions in the chest, its anatomically complicated structure, and the thin bone cortex. We propose a new method using unsupervised generative attentional networks with adaptive layer-instance normalisation for image-to-image translation (U-GAT-IT), which specialised in unpaired image transformation based on attention maps for image transformation. We added the modality-independent neighbourhood descriptor (MIND) to the loss of U-GAT-IT to guarantee anatomical consistency in the image transformation between different domains. Our proposed method obtained a synthesised computed tomography of the chest. Experimental results showed that our method outperforms current approaches. The study findings suggest the possibility of synthesising clinically acceptable computed tomography images from chest MRI with minimal changes in anatomical structures without human annotation.Springer Science and Business Media LLC, Jun. 2022, Scientific reports, 12(1) (1), 11090 - 11090, English, International magazineScientific journal

- ABSTRACT: A 52-year-old woman with a rapidly growing uterine tumor suspected of uterine sarcoma underwent 18F-FDG PET/MRI, revealing a myometrial mass and an endometrial lesion, suggesting dual primary neoplasms. Based on the PET/MRI findings, we changed the intraoperative procedure to determine the necessity of pelvic lymphadenectomy. PET/MRI was useful in diagnosing and differentiating between 2 malignant neoplasms in the uterus compared with PET/CT, due to MRI's high contrast resolution and precise fusion due to the simultaneous acquisition.Jun. 2022, Clinical nuclear medicine, 47(6) (6), e452-e454, English, International magazineScientific journal

- Viral hepatitis was previously the most common cause of chronic liver disease. However, in recent years, nonalcoholic fatty liver disease (NAFLD) cases have been increasing, especially in developed countries. NAFLD is histologically characterized by fat, fibrosis, and inflammation in the liver, eventually leading to cirrhosis and hepatocellular carcinoma. Although biopsy is the gold standard for the assessment of the liver parenchyma, quantitative evaluation methods, such as ultrasound, CT, and MRI, have been reported to have good diagnostic performances. The quantification of liver fat, fibrosis, and inflammation is expected to be clinically useful in terms of the prognosis, early intervention, and treatment response for the management of NAFLD. The aim of this review was to discuss the basics and prospects of MRI-based tissue quantifications of the liver, mainly focusing on proton density fat fraction for the quantification of fat deposition, MR elastography for the quantification of fibrosis, and multifrequency MR elastography for the evaluation of inflammation.Japanese Society for Magnetic Resonance in Medicine, May 2022, Magn Reson Med Sci[Epub ahead of print], English, Domestic magazine[Refereed]Scientific journal
- This retrospective study aimed to develop and validate a deep learning model for the classification of coronavirus disease-2019 (COVID-19) pneumonia, non-COVID-19 pneumonia, and the healthy using chest X-ray (CXR) images. One private and two public datasets of CXR images were included. The private dataset included CXR from six hospitals. A total of 14,258 and 11,253 CXR images were included in the 2 public datasets and 455 in the private dataset. A deep learning model based on EfficientNet with noisy student was constructed using the three datasets. The test set of 150 CXR images in the private dataset were evaluated by the deep learning model and six radiologists. Three-category classification accuracy and class-wise area under the curve (AUC) for each of the COVID-19 pneumonia, non-COVID-19 pneumonia, and healthy were calculated. Consensus of the six radiologists was used for calculating class-wise AUC. The three-category classification accuracy of our model was 0.8667, and those of the six radiologists ranged from 0.5667 to 0.7733. For our model and the consensus of the six radiologists, the class-wise AUC of the healthy, non-COVID-19 pneumonia, and COVID-19 pneumonia were 0.9912, 0.9492, and 0.9752 and 0.9656, 0.8654, and 0.8740, respectively. Difference of the class-wise AUC between our model and the consensus of the six radiologists was statistically significant for COVID-19 pneumonia (p value = 0.001334). Thus, an accurate model of deep learning for the three-category classification could be constructed; the diagnostic performance of our model was significantly better than that of the consensus interpretation by the six radiologists for COVID-19 pneumonia.May 2022, Scientific Reports, 12(1) (1), 8214 - 8214, English, International magazine[Refereed]Scientific journal
- Response Evaluation Criteria in Solid Tumors (RECIST) is inappropriate to assess the direct effects of treatment on hepatocellular carcinoma (HCC) by locoregional therapies, such as radiofrequency ablation or transarterial chemoembolization. Therefore, establishment of response evaluation criteria solely devoted to HCC is needed in clinical practice, as well as in clinical trials of HCC treatment, such as systemic therapies, which cause necrosis of the tumor. Response Evaluation Criteria in Cancer of the Liver (RECICL) was revised in 2021 by the Liver Cancer Study Group of Japan based on the 2019 version of RECICL, which was commonly used in Japan. The major revised points of the RECICL 2021 is inclusion of RECIST version 1.1 and modified RECIST as response evaluation criteria in systemic therapy for HCC. We hope this new treatment response criteria, RECICL, proposed by the Liver Cancer Study Group of Japan will benefit the HCC treatment response evaluation in the setting of daily clinical practice and clinical trials as well, not only in Japan, but also internationally.Wiley, Apr. 2022, Hepatology research : the official journal of the Japan Society of Hepatology, 52(4) (4), 329 - 336, English, International magazineScientific journal
- OBJECTIVE: In renal cell carcinoma with inferior vena cava (IVC) thrombus, adhesion to, or invasion into, the IVC wall will often increase the level of surgical difficulty and even necessitate resection of the IVC. It will generally be difficult to perform an accurate preoperative assessment using the standard imaging modalities of contrast-enhanced computed tomography and standard magnetic resonance imaging (MRI). Cine MRI is an MRI sequence that captures motion to produce detailed information on both the anatomy and the dynamic motion. In the present study, we evaluated the accuracy of preoperative cine MRI for determining the need for IVC wall resection, with validation of the imaging findings according to the intraoperative findings. METHODS: A total of 15 patients who had undergone radical nephrectomy and tumor thrombectomy from May 2018 to April 2020 met the inclusion criteria. The primary outcome of interest was the need for IVC resection because of adhesion or invasion of a venous tumor thrombus. Cine MRI was used to evaluate the blood flow between the tumor thrombus and the IVC wall and the presence of tumor thrombus mobility during free respiration. The sensitivity and specificity were calculated for preoperative cine MRI for determining the need for IVC wall resection. The Fisher exact test was used to determine the association between intraoperative IVC wall resection and the cine MRI findings. Furthermore, receiver operating characteristic curves and the area under the curve were used to compare the accuracy of conventional MRI and cine MRI. RESULTS: Of the 15 patients, 8 (53.3%) had undergone IVC resection. We found that the absence of both dynamic blood flow and tumor thrombus mobility on cine MRI could reliably predict for IVC resection with 100% (95% confidence interval, 51.8%-100%) sensitivity and 85.7% (95% confidence interval, 42.1%-1.00%) specificity. The area under the receiver operating characteristic curve was 0.821 for conventional MRI and 0.929 for cine MRI. CONCLUSIONS: In the preoperative setting, cine MRI could be a helpful examination modality to predict for the need for IVC wall resection for patients with renal cell carcinoma with venous tumor thrombus.Mar. 2022, Journal of vascular surgery.

- For assessing a cancer treatment, and for detecting and characterizing cancer, Diffusion-weighted imaging (DWI) is commonly used. The key in DWI’s use extracranially has been due to the emergence of of high-gradient amplitude and multichannel coils, parallelimaging, and echo-planar imaging. The benefit has been fewer motion artefacts and high-quality prostate images.Recently, new techniques have been developed to improve the signal-to-noise ratio of DWI with fewer artefacts, allowing an increase in spatial resolution. For apparent diffusion coefficient quantification, non-Gaussian diffusion models have been proposed as additional tools for prostate cancer detection and evaluation of its aggressiveness. More recently, radiomics and machine learning for prostate magnetic resonance imaging have emerged as novel techniques for the non-invasive characterisation of prostate cancer. This review presents recent developments in prostate DWI and discusses its potential use in clinical practice.British Institute of Radiology, Mar. 2022, The British Journal of Radiology, 95(1131) (1131)Scientific journal

- Background: Prostate apparent diffusion coefficient (ADC) values calculated from diffusion-weighted imaging have been used for evaluating prostate cancer (PCa) aggressiveness. However, the way of measuring ADC values has varied depending on the study. Purpose: To investigate inter- and intra-reader variability and diagnostic performance of three kinds of shaped 2D regions of interests (ROIs) for tumor ADC measurements in PCa. Material and Methods: Seventy-four patients with PCa undergoing 3-T MRI before surgery were included. Histologic findings from radical prostatectomy specimens were reviewed to define each patient's dominant tumor. Three readers independently measured the tumor ADCs using three different ROI methods: freehand, large-circle, and small-circles ROIs. Readers repeated measurements after 3 weeks. Bland-Altman analysis was performed to evaluate the inter- and intra-reader variability. Receiver Operating Characteristic analysis was used for assessment of tumor aggressiveness for PCa. Results: For intra-reader and inter-reader variability, the mean coefficient of repeatability for freehand ROIs, large-circle ROIs, and small-circles ROIs were as follows: 13.7%, 12.4%, and 11.5%; 9.4%, 9.7%, and 9.5%. For differentiating Gleason score (GS) = 3 + 3 from GS ≥ 3 + 4 tumors, the area under the curves were 0.90 for freehand ROIs, 0.89 for large-circle ROIs, and 0.94 small-circles ROIs (p = 0.31). Conclusion: The variations in ROI method did not have a major influence on intra-reader or inter-reader reproducibility or diagnostic performance for prostate ADC measurements.Mar. 2022, Acta radiologica open, 11(3) (3), 20584601221086500 - 20584601221086500, English, International magazineScientific journal
- OBJECTIVE: To investigate the diagnostic performance of the extracellular volume (ECV) fraction in multiphasic contrast-enhanced computed tomography (CE-CT) for estimating histologic pancreatic fibrosis and predicting postoperative pancreatic fistula (POPF). METHODS: Eighty-five patients (49 men; mean age, 69 years) who underwent multiphasic CE-CT followed by pancreaticoduodenectomy with pancreaticojejunal anastomosis between January 2012 and December 2018 were retrospectively included. The ECV fraction was calculated from absolute enhancements of the pancreas and aorta between the precontrast and equilibrium-phase images, followed by comparisons among histologic pancreatic fibrosis grades (F0‒F3). The diagnostic performance of the ECV fraction in advanced fibrosis (F2‒F3) was evaluated using receiver operating characteristic curve analysis. Multivariate logistic regression analysis was used to evaluate the associations of the risk of POPF development with patient characteristics, histologic findings, and CT imaging parameters. RESULTS: The mean ECV fraction of the pancreas was 34.4% ± 9.5, with an excellent intrareader agreement of 0.811 and a moderate positive correlation with pancreatic fibrosis (r = 0.476; p < 0.001). The mean ECV fraction in advanced fibrosis was significantly higher than that in no/mild fibrosis (44.4% ± 10.8 vs. 31.7% ± 6.7; p < 0.001), and the area under the receiver operating characteristic curve for the diagnosis of advanced fibrosis was 0.837. Twenty-two patients (25.9%) developed clinically relevant POPF. Multivariate logistic regression analysis demonstrated that the ECV fraction was a significant predictor of POPF. CONCLUSIONS: The ECV fraction can offer quantitative information for assessing pancreatic fibrosis and POPF after pancreaticojejunal anastomosis. KEY POINTS: • There was a moderate positive correlation of the extracellular volume (ECV) fraction of the pancreas in contrast-enhanced CT with the histologic grade of pancreatic fibrosis (r = 0.476; p < 0.001). • The ECV fraction was higher in advanced fibrosis (F2‒F3) than in no/mild fibrosis (F0‒F1) (p < 0.001), with an AUC of 0.837 for detecting advanced fibrosis. • The ECV fraction was an independent risk factor for predicting subclinical (odds ratio, 0.81) and clinical (odds ratio, 0.80) postoperative pancreatic fistula.Mar. 2022, European radiology, 32(3) (3), 1770 - 1780, English, International magazineScientific journal

- OBJECTIVE: The purpose of this study was to investigate outcomes of transarterial chemoembolization (TACE) in treating hepatocellular carcinoma (HCC) comparing the different approaches used in Germany and Japan. METHODS: This binational IRB-approved retrospective dual-center study included a total of 94 HCC patients subdivided in a German and a Japanese cohort. For each patient, liver and tumor volumetry was performed using computed tomography (CT) and magnetic resonance imaging (MRI). Furthermore, a comprehensive risk profile, including body constitution and liver and kidney function was established. Primary endpoints were progression-free and overall survival (PFS/OS). RESULTS: PFS in the German cohort was 168 vs 224d in the Japanese cohort (p=0.640). When subdivided by BCLC stage, no significant differences were reported (p=0.160-0.429). OS was significantly longer in the Japanese cohort with 856 vs. 303d (p<0.001). OS for BCLC A was significantly longer in the Japanese cohort (1960 vs. 428d; p<0.001), while survival rates did not differ significantly in BCLC B (785 vs 330d; p=0.067) and C-stages (208 vs 302d; p=0.186). Older age (p=0.034), poorer liver/kidney function (p=0.025-0-035), and a higher liver/tumor ratio (p<0.001) were found to correlate with shorter survival. ECOG scores were significantly higher in the German cohort (p=0.002). CONCLUSION: While OS is longer in TACE-treated patients in the Japanese cohort compared to the German cohort, the two approaches seem to be equally effective as PFS does not differ significantly. The different survival rates may be caused by the different clinical performance status of the selected collectives. In very early and early stage HCC, TACE in Japan seems to be an effective treatment option while in Germany for patients in those stages TACE remains a second-line option for patients not available for surgery or ablation.2022, Journal of hepatocellular carcinoma, 9, 695 - 705, English, International magazineScientific journal

- In the 22nd Nationwide Follow-up Survey of Primary Liver Cancer in Japan, data from 21 155 newly registered patients and 43 041 previously registered follow-up patients were compiled from 538 institutions over a 2-year period from January 1, 2012 to December 31, 2013. Basic statistics compiled for patients newly registered in the 22nd survey were cause of death, past medical history, clinical diagnosis, imaging diagnosis, treatment-related factors, pathologic diagnosis, recurrence status and autopsy findings. Compared with the previous 21st survey, the population of patients with hepatocellular carcinoma (HCC) was older at the time of clinical diagnosis, had more female patients, more patients with non-B non-C HCC, smaller tumor diameter and was more frequently treated with hepatectomy. Cumulative survival rates were calculated for HCC, intrahepatic cholangiocarcinoma, and combined hepatocellular cholangiocarcinoma (combined HCC and intrahepatic cholangiocarcinoma) by treatment type and background characteristics for patients newly registered between 2002 and 2013 whose final outcome was survival or death. Median overall survival and cumulative survival rates for HCC were calculated by dividing patients by combinations of background factors (number of tumors, tumor diameter or Child-Pugh grade) and by treatment type (hepatectomy, radiofrequency ablation therapy, transcatheter arterial chemoembolization, hepatic arterial infusion chemotherapy and systemic therapy). The same values were also calculated according to registration date by dividing patients newly registered between 1978 and 2013 into five time period groups. The data obtained from this nationwide follow-up survey are expected to contribute to advancing clinical research and treatment of primary liver cancer worldwide.Wiley, Jan. 2022, Hepatology research : the official journal of the Japan Society of Hepatology, 52(1) (1), 5 - 66, English, International magazineScientific journal

- PURPOSE: The purpose is to investigate the major and minor complications of the pancreas after transcatheter arterial embolization (TAE) using n-butyl-2-cyanoacrylate (NBCA) for bleeding from pancreatic arteries. MATERIALS AND METHODS: Thirty-three patients who underwent TAE using NBCA for acute bleeding from pancreatic arteries and their parent arteries followed by contrast-enhanced computed tomography (CE-CT) were evaluated retrospectively. Complications and risk factors were assessed using Mann-Whitney U test or Fisher's exact test for the univariate analysis. Patients' characteristic, embolized artery, procedure details, and clinical outcomes were examined as possible risk factors. RESULTS: TAE was performed successfully in all patients. Minor pancreatic complications occurred in 10 patients (30%), including acute mild pancreatitis (n = 4) and focal lack of pancreatic parenchymal enhancement on CE-CT without pancreatitis (n = 6). No cases of major pancreatic complications, such as moderate/severe pancreatitis, were reported. Embolized artery was the only significant risk factor. The rate of complications per embolized artery were 15% (three out of 20 patients) in the arteries of the pancreatic head and 54% (seven out of 13 patients) in the arteries of pancreatic body and tail (p = 0.025). CONCLUSION: TAE using NBCA for acute bleeding from pancreatic arteries is efficacious and safe. Mild pancreatic complications were observed more frequently in case of embolization of the pancreatic body and tail region than the pancreatic head.Springer Science and Business Media LLC, Oct. 2021, Japanese journal of radiology, 40(3) (3), 308 - 317, English, Domestic magazineScientific journal

- PURPOSE: This study aimed to examine MRI features and staging of neuroendocrine carcinoma (NEC) of the endometrium and evaluate survival. METHODS: Clinical data, pathological, and preoperative pelvic MRI findings in 22 patients with histologically surgery-proven endometrial NEC were retrospectively reviewed. Tumors were pure NEC (n = 10) or mixed histotype (n = 12), with 13 large and nine small cell type. RESULTS: International Federation of Gynecology and Obstetrics (FIGO) staging was I, II, III, and IV in 6, 2, 12, and 2 patients, respectively. In 13 (76.4%) of 17 patients with pathological deep myometrial invasion, MRI showed abnormal diffusely infiltrative high T2 signal intensity throughout the myometrium with loss of normal uterine architecture. All tumors had restricted diffusion (apparent diffusion coefficient map low signal intensity, diffusion weighted imaging high signal intensity). Accuracy of T staging by MRI for all cases was 81.8%, with reference to pathology staging, while patient-based sensitivity, specificity, and accuracy for detecting metastatic pelvic lymph nodes was 60.0%, 100%, and 77.8%, respectively. Two intrapelvic peritoneal dissemination cases were detected by MRI. During follow-up (mean 30.4, range 3.3-138.4 months), 16 patients (72.7%) experienced recurrence and 12 (54.5%) died of disease. Two-year disease-free and overall survival rates for FIGO I, II, III, and IV were 66.7% and 83.3%, 50% and 100%, 10% and 33.3%, and 0% and 0%, respectively. CONCLUSION: Abnormal diffusely infiltrative high T2 signal intensity throughout the myometrium with normal uterine architecture loss and obvious restricted diffusion throughout the tumor are suggestive features of endometrial NEC. Pelvic MRI is reliable for intrapelvic staging of affected patients.Sep. 2021, Magnetic resonance in medical sciences : MRMS : an official journal of Japan Society of Magnetic Resonance in Medicine, 20(3) (3), 236 - 244, English, Domestic magazineScientific journal
- Gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA; Gadoxetic acid; Gadoxetate disodium) is a hepatocyte-specific MR contrast agent. It acts as an extracellular contrast agent in the early phase after intravenous injection, and then is taken up by hepatocytes later. Using this contrast agent, we can evaluate the hemodynamics of the liver and liver tumors, and can therefore improve the detection and characterization of hepatocellular carcinoma (HCC). Gd-EOB-DTPA helps in the more accurate detection of hypervascular HCC than by other agents. In addition, Gd-EOB-DTPA can detect hypovascular HCC, which is an early stage of the multi-stage carcinogenesis, with a low signal in the hepatobiliary phase. In addition to tumor detection and characterization, Gd-EOB-DTPA contrast-enhanced MR imaging can be applied for liver function evaluation and prognoses evaluation. Thus, Gd-EOB-DTPA plays an important role in the diagnosis of HCC. However, we have to employ optimal imaging techniques to improve the diagnostic ability. In this review, we aimed to discuss the characteristics of the contrast media, optimal imaging techniques, diagnosis, and applications.Aug. 2021, Magnetic resonance in medical sciences : MRMS : an official journal of Japan Society of Magnetic Resonance in Medicine, 21(1) (1), 168 - 181, English, Domestic magazineScientific journal

- AIM: We reviewed the data of a nationwide follow-up survey to determine the impact of hepatitis C virus (HCV) infection on the outcomes of hepatectomy for mass-forming (MF) type, and combined mass-forming and periductal infiltrating (MF + PI) type intrahepatic cholangiocarcinoma (ICC). METHODS: In total, 956 patients with ICC who underwent curative hepatic resection were included in this cohort study, and patients were classified according to virus status. Patients were classified according to virus status as follows: HCV-related ICC (n = 138, 14.4%), hepatitis B virus (HBV)-related ICC (n = 43, 4.5%) and non-virus-related ICC (n = 775, 81.1%). To control for variables, we used 1:1 propensity score-matching to compare outcomes after surgery between HCV-related (n = 102) and non-virus-related ICC cases (n = 102). RESULTS: We successfully matched HCV-related and non-virus-related ICC cases with similar liver function and tumor characteristics. Patients with HCV-related ICC had significantly shorter recurrence-free survival (hazard ratio 0.62, 95% confidence interval 0.42-0.92, p = 0.016) and overall survival (hazard ratio: 0.57, 95% confidence interval: 0.37-0.88, p = 0.011) than patients with non-virus-related ICC. Cox proportional hazard analysis showed that HCV-related ICC offered a worse prognosis than non-virus-related ICC. CONCLUSIONS: HCV infection increases the risk of recurrence and worsens overall survival in patients after curative resection for MF and combined MF + PI type ICC.Wiley, Aug. 2021, Hepatology research : the official journal of the Japan Society of Hepatology, 51(8) (8), 890 - 901, English, International magazineScientific journal
- PURPOSE: To evaluate the efficacy of superselective transcatheter arterial embolization (TAE) for intractable postpartum hemorrhage (PPH) due to genital tract trauma (GTT) after vaginal delivery. METHODS: We evaluated 27 patients who underwent TAE for intractable PPH due to GTT after vaginal delivery at our institution between January 2008 and December 2020. Patients were divided into two groups according to TAE procedure; TAE performed as close as possible to the bleeding point, at least more peripherally than the second branch of the anterior division of the internal iliac artery, was defined as superselective TAE (S-TAE). TAE performed from the proximal segment of the internal iliac artery was defined as proximal TAE (P-TAE). Patient characteristics, pre-procedural contrast-enhanced computed tomography (CE-CT), procedure details, technical/clinical success, and complications were evaluated separately for the S-TAE and P-TAE groups. RESULTS: The combined technical/clinical success rate was 92%. No major procedure-related complications were seen (mean follow-up: 6.12 ± 3.93 days). The combined technical/clinical success rate of S-TAE was 100% and of P-TAE was 67% (p = 0.04). S-TAE was performed more frequently in patients with pre-procedural CE-CT (p = 0.01) and use of permanent embolic materials (p = 0.003). CONCLUSION: S-TAE is safe and effective for intractable PPH due to GTT. Pre-procedural CE-CT may be useful for detecting the culprit artery and be helpful in performing S-TAE.Jul. 2021, Emergency radiology[Epub ahead of print], 28(6) (6), 1127 - 1133, English, International magazine[Refereed]Scientific journal
- OBJECTIVE: To evaluate the interreader agreement and diagnostic performance of the Prostate Imaging Reporting and Data System (PI-RADS) v. 2.1, in comparison with v. 2. METHODS: Institutional review board approval was obtained for this retrospective study. 77 consecutive patients who underwent a prostate multiparametric magnetic resonance imaging at 3.0 T before radical prostatectomy were included. Four radiologists (two experienced uroradiologists and two inexperienced radiologists) independently scored eight regions [six peripheral zones (PZ) and two transition zones (TZ)] using v. 2.1 and v. 2. Interreader agreement was assessed using κ statistics. To evaluate diagnostic performance for clinically significant prostate cancer (csPC), area under the curve (AUC) was estimated. RESULTS: 228 regions were pathologically diagnosed as positive for csPC. With a cut-off ≥3, the agreement among all readers was better with v. 2.1 than v. 2 in TZ, PZ, or both zones combined (κ-value: TZ, 0.509 vs 0.414; PZ, 0.686 vs 0.568; both zones combined, 0.644 vs 0.531). With a cut-off ≥4, the agreement among all readers was also better with v. 2.1 than v. 2 in the PZ or both zones combined (κ-value: PZ, 0.761 vs 0.701; both zones combined, 0.756 vs 0.709). For all readers, AUC with v. 2.1 was higher than with v. 2 (TZ, 0.826-0.907 vs 0.788-0.856; PZ, 0.857-0.919 vs 0.853-0.902). CONCLUSION: Our study suggests that the PI-RADS v. 2.1 could improve the interreader agreement and might contribute to improved diagnostic performance compared with v. 2. ADVANCES IN KNOWLEDGE: PI-RADS v. 2.1 has a potential to improve interreader variability and diagnostic performance among radiologists with different levels of expertise.Jul. 2021, The British journal of radiology, 95(1131) (1131), 20201434 - 20201434, English, International magazineScientific journal

Background Technological developments have led to an increased usage of external-body radiotherapy (RT) for the treatment of hepatocellular carcinoma (HCC). Transcatheter arterial chemoembolization (TACE) may be required later in patients treated with RT because of the high recurrence rate and multinodular presentation of HCC. However, despite the risk of liver function impairment, the cumulative liver damage correlated with TACE following a hepatic RT has not been adequately assessed.Purpose To evaluate the feasibility of TACE following RT for HCC.Materials and methods Sixty-seven patients with HCC who underwent TACE after RT were retrospectively evaluated between 2012 and 2018. We assessed increases in Child–Turcotte–Pugh (CTP) by ≥2 points at 1 month, the incidence of major complications, survival duration, and short-term mortality within 6 months after TACE. Furthermore, we evaluated the predictive factors for liver function impairment and short-term mortality.Results Eight patients experienced a CTP increase ≥2 points at 1 month. There were no cases of liver abscesses or bilomas. Nine patients died within 6 months following TACE. The mean liver dose (MLD) was a significant predictor of liver function impairment at 1 month ( p = 0.042). Low liver functional reserve, distant metastasis ( p = 0.037), MLD ( p = 0.046), TACE type ( p = 0.025), and TACE within 3 months following RT ( p = 0.007) were significant predictors of short-term mortality.Conclusions Despite the feasibility of TACE following RT, clinicians should pay attention to impaired pretreatment liver function, following high dose RT, and the short duration between RT and TACE.Scientific journal - Impact Journals, LLC, Jun. 2021, Oncotarget, 12(12) (12), 1187 - 1196Scientific journal
- The Clinical Practice Manual for Hepatocellular Carcinoma was published based on evidence confirmed by the Evidence-based Clinical Practice Guidelines for Hepatocellular Carcinoma along with consensus opinion among a Japan Society of Hepatology (JSH) expert panel on hepatocellular carcinoma (HCC). Since the JSH Clinical Practice Guidelines are based on original articles with extremely high levels of evidence, expert opinions on HCC management in clinical practice or consensus on newly developed treatments are not included. However, the practice manual incorporates the literature based on clinical data, expert opinion, and real-world clinical practice currently conducted in Japan to facilitate its use by clinicians. Alongside each revision of the JSH Guidelines, we issued an update to the manual, with the first edition of the manual published in 2007, the second edition in 2010, the third edition in 2015, and the fourth edition in 2020, which includes the 2017 edition of the JSH Guideline. This article is an excerpt from the fourth edition of the HCC Clinical Practice Manual focusing on pathology, diagnosis, and treatment of HCC. It is designed as a practical manual different from the latest version of the JSH Clinical Practice Guidelines. This practice manual was written by an expert panel from the JSH, with emphasis on the consensus statements and recommendations for the management of HCC proposed by the JSH expert panel. In this article, we included newly developed clinical practices that are relatively common among Japanese experts in this field, although all of their statements are not associated with a high level of evidence, but these practices are likely to be incorporated into guidelines in the future. To write this article, coauthors from different institutions drafted the content and then critically reviewed each other's work. The revised content was then critically reviewed by the Board of Directors and the Planning and Public Relations Committee of JSH before publication to confirm the consensus statements and recommendations. The consensus statements and recommendations presented in this report represent measures actually being conducted at the highest-level HCC treatment centers in Japan. We hope this article provides insight into the actual situation of HCC practice in Japan, thereby affecting the global practice pattern in the management of HCC.S.

- INTRODUCTION: Most studies predicting survival after resection, transarterial chemoembolization (TACE), and ablation analyzed diameter and number of hepatocellular carcinomas (HCCs) as dichotomous variables, resulting in an underestimation of risk variation. We aimed to develop and validate a new prognostic model for patients with HCC using largest diameter and number of HCCs as continuous variables. METHODS: The prognostic model was developed using data from patients undergoing resection, TACE, and ablation in 645 Japanese institutions. The model results were shown after balanced using the inverse probability of treatment-weighted analysis and were externally validated in an international multi-institution cohort. RESULTS: Of 77,268 patients, 43,904 patients, including 15,313 (34.9%) undergoing liver resection, 13,375 (30.5%) undergoing TACE, and 15,216 (34.7%) undergoing ablation, met the inclusion criteria. Our model (http://www.u-tokyo-hbp-transplant-surgery.jp/about/calculation.html) showed that the 5-year overall survival (OS) in patients with HCC undergoing these procedures decreased with progressive incremental increases in diameter and number of HCCs. For patients undergoing resection, the inverse probability of treatment-weighted-adjusted 5-year OS probabilities were 10%-20% higher compared with patients undergoing TACE for 1-6 HCC lesions <10 cm and were also 10%-20% higher compared with patients undergoing ablation when the HCC diameter was 2-3 cm. For patients undergoing resection and TACE, the model performed well in the external cohort. DISCUSSION: Our novel prognostic model performed well in predicting OS after resection and TACE for HCC and demonstrated that resection may have a survival benefit over TACE and ablation based on the diameter and number of HCCs.Apr. 2021, The American journal of gastroenterology[Epub ahead of print], 116(8) (8), 1698 - 1708, English, International magazine[Refereed]Scientific journal
- OBJECTIVES: To evaluate a deep learning model for predicting gestational age from fetal brain MRI acquired after the first trimester in comparison to biparietal diameter (BPD). MATERIALS AND METHODS: Our Institutional Review Board approved this retrospective study, and a total of 184 T2-weighted MRI acquisitions from 184 fetuses (mean gestational age: 29.4 weeks) who underwent MRI between January 2014 and June 2019 were included. The reference standard gestational age was based on the last menstruation and ultrasonography measurements in the first trimester. The deep learning model was trained with T2-weighted images from 126 training cases and 29 validation cases. The remaining 29 cases were used as test data, with fetal age estimated by both the model and BPD measurement. The relationship between the estimated gestational age and the reference standard was evaluated with Lin's concordance correlation coefficient (ρc) and a Bland-Altman plot. The ρc was assessed with McBride's definition. RESULTS: The ρc of the model prediction was substantial (ρc = 0.964), but the ρc of the BPD prediction was moderate (ρc = 0.920). Both the model and BPD predictions had greater differences from the reference standard at increasing gestational age. However, the upper limit of the model's prediction (2.45 weeks) was significantly shorter than that of BPD (5.62 weeks). CONCLUSIONS: Deep learning can accurately predict gestational age from fetal brain MR acquired after the first trimester. KEY POINTS: • The prediction of gestational age using ultrasound is accurate in the first trimester but becomes inaccurate as gestational age increases. • Deep learning can accurately predict gestational age from fetal brain MRI acquired in the second and third trimester. • Prediction of gestational age by deep learning may have benefits for prenatal care in pregnancies that are underserved during the first trimester.Apr. 2021, European radiology[Epub ahead of print], 31(6) (6), 3775 - 3782, English, International magazine[Refereed]Scientific journal

- In the 21st Nationwide Follow-up Survey of Primary Liver Cancer in Japan, data from 22,134 new patients and 41,956 previously followed patients were compiled from 546 institutions over a 2-year period from 1 January 2010 to 31 December 2011. Basic statistics compiled for patients newly registered in the 21st survey were cause of death, medical history, clinical diagnosis, imaging diagnosis, treatment-related factors, pathological diagnosis, recurrence status, and autopsy findings. Compared with the previous 20th survey, the population of patients with hepatocellular carcinoma (HCC) was older at the time of clinical diagnosis, had more female patients, had more patients with non-B non-C HCC, had smaller tumor diameter, and was more frequently treated with hepatectomy and with radiofrequency ablation. Cumulative survival rates were calculated for HCC, intrahepatic cholangiocarcinoma, and combined hepatocellular cholangiocarcinoma (combined HCC and intrahepatic cholangiocarcinoma) by treatment type and background characteristics for patients newly registered between 1998 and 2011 whose final outcome was survival or death (excluding unknown). Cumulative survival rates for HCC were calculated by dividing patients by combinations of background factors (number of tumors, tumor diameter, and Child-Pugh grade) and by treatment type (hepatectomy, local ablation therapy, transcatheter arterial chemoembolization, and hepatic arterial infusion chemotherapy). The same values were also calculated according to registration date by dividing patients newly registered between 1978 and 2011 into four time-period groups. The data obtained from this nationwide follow-up survey are expected to contribute to advancing clinical research and treatment of primary liver cancer.Wiley, Apr. 2021, Hepatology Research, 51(4) (4), 355 - 405, English, International magazine[Refereed]Scientific journal

Purpose To retrospectively assess the repeatability of physiological F-18 labeled fluorodeoxyglucose (FDG) uptake in the skin on positron emission tomography/magnetic resonance imaging (PET/MRI) and explore its regional distribution and relationship with sex and age.Methods Out of 562 examinations with normal FDG distribution on whole-body PET/MRI, 74 repeated examinations were evaluated to assess the repeatability and regional distribution of physiological skin uptake. Furthermore, 224 examinations were evaluated to compare differences in the uptake due to sex and age. Skin segmentation on PET was performed as body-surface contouring on an MR-based attenuation correction map using an off-line reconstruction software. Bland–Altman plots were created for the repeatability assessment. Kruskal–Wallis test was performed to compare the maximum standardized uptake value (SUVmax) with regional distribution, age, and sex.Results The limits of agreement for the difference in SUVmean and SUVmax of the skin were less than 30%. The highest SUVmax was observed in the face (3.09±1.04), followed by the scalp (2.07±0.53). The SUVmax in the face of boys aged 0–9 years and 10–20 years (1.33±0.64 and 2.05±1.00, respectively) and girls aged 0–9 years (0.98±0.38) was significantly lower than that of men aged ≥20 years and girls aged ≥10 years (p<0.001). In women, the SUVmax of the face (2.31±0.71) of ≥70-year-olds was significantly lower than that of 30–39-year-olds (3.83±0.82) (p<0.05).Conclusion PET/MRI enabled the quantitative analysis of skin FDG uptake with repeatability. The degree of physiological FDG uptake in the skin was the highest in the face and varied between sexes. Although attention to differences in body habitus between age groups is needed, skin FDG uptake also depended on age.[Refereed]Scientific journal - Background: We investigate the feasibility of image fusion application for ablative margin assessment in radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) and possible causes for a wrong initial evaluation of technical success through a side-by-side comparison. Methods: A total of 467 patients with 1100 HCCs who underwent RFA were reviewed retrospectively. Seventeen patients developed local tumor progressions (LTPs) (median size, 1.0 cm) despite initial judgments of successful ablation referring to contrast-enhanced images obtained in the 24 h after ablation. The ablative margins were reevaluated radiologically by overlaying fused images pre- and post-ablation. Results: The initial categorizations of the 17 LTPs had been grade A (absolutely curative) (n = 5) and grade B (relatively curative) (n = 12); however, the reevaluation altered the response categories to eight grade C (margin-zero ablation) and nine grade D (existence of residual HCC). LTP occurred in eight patients re-graded as C within 4 to 30.3 months (median, 14.3) and in nine patients re-graded as D within 2.4 to 6.7 months (median, 4.2) (p = 0.006). Periablational hyperemia enhancements concealed all nine HCCs reevaluated as grade D. Conclusion: Side-by-side comparisons carry a risk of misleading diagnoses for LTP of HCC. Overlay fused imaging technology can be used to evaluate HCC ablative margin with high accuracy.MDPI AG, Mar. 2021, Cancers, 13(6) (6), 1460 - 1460, EnglishScientific journal

- Carbon dioxide (CO2) treatment is reported to have an antitumor effect owing to the improvement in intratumoral hypoxia. Previous studies were based on histological analysis alone. In the present study, the improvement in intratumoral hypoxia by percutaneous CO2 treatment in vivo was determined using 18F-fluoromisonidazole positron emission tomography-computed tomography (18F-FMISO PET-CT) images. Twelve Japanese nude mice underwent implantation of LM8 tumor cells in the dorsal subcutaneous area 2 weeks before percutaneous CO2 treatment and 18F-FMISO PET-CT scans. Immediately after intravenous injection of 18F-FMISO, CO2 and room air were administered transcutaneously in the CO2-treated group (n=6) and a control group (n=6), respectively; each treatment was performed for 10 minutes. PET-CT was performed 2 h after administration of 18F-FMISO. 18F-FMISO tumor uptake was quantitatively evaluated using the maximum standardized uptake value (SUVmax), tumor-to-liver ratio (TLR), tumor-to-muscle ratio (TMR), metabolic tumor volume (MTV) and total lesion glycolysis (TLG). Mean ± standard error of the mean (SEM) of the tumor volume was not significantly different between the two groups (CO2-treated group, 1.178±0.450 cm3; control group, 1.368±0.295 cm3; P=0.485). Mean ± SEM of SUVmax, TLR, MTV (cm3) and TLG were significantly lower in the CO2-treated group compared with the control group (0.880±0.095 vs. 1.253±0.071, P=0.015; 1.063±0.147361 vs. 1.455±0.078, P=0.041; 0.353±0.139 vs. 1.569±0.438, P=0.015; 0.182±0.070 vs. 1.028±0.338, P=0.015), respectively. TMR was not significantly different between the two groups (4.520±0.503 vs. 5.504±0.310; P=0.240). In conclusion, 18F-FMISO PET revealed that percutaneous CO2 treatment improved intratumoral hypoxia in vivo. This technique enables assessment of the therapeutic effect in CO2 treatment by imaging, and may contribute to its clinical application.Mar. 2021, Oncology letters, 21(3) (3), 207 - 207, English, International magazine[Refereed]Scientific journal
- AIM: To investigate the relationships between various clinical variables and the metformin-induced accumulation of fluorodeoxyglucose (FDG) in the intestine, with distinction between the intestinal wall and lumen, in individuals with type 2 diabetes who were receiving metformin treatment and underwent 18 F-labelled FDG ([18 F]FDG) positron emission tomography (PET)-MRI. MATERIALS AND METHODS: We evaluated intestinal accumulation of [18 F]FDG with both subjective (a five-point visual scale determined by two experienced radiologists) and objective analyses (measurement of the maximum standardized uptake value [SUVmax ]) in 26 individuals with type 2 diabetes who were receiving metformin and underwent [18 F]FDG PET-MRI. [18 F]FDG accumulation within the intestinal wall was discriminated from that in the lumen on the basis of SUVmax . RESULTS: SUVmax for the large intestine was correlated with blood glucose level (BG) and metformin dose, but not with age, body mass index, HbA1c level or estimated glomerular filtration rate (eGFR). SUVmax for the small intestine was not correlated with any of these variables. Visual scale analysis yielded essentially similar results. Metformin dose and eGFR were correlated with SUVmax for the wall and lumen of the large intestine, whereas BG was correlated with that for the wall. Multivariable analysis identified metformin dose as an explanatory factor for SUVmax in the wall and lumen of the large intestine after adjustment for potential confounders including BG and eGFR. CONCLUSIONS: Metformin dose is an independent determinant of [18 F]FDG accumulation in the wall and lumen of the large intestine in individuals treated with this drug.Wiley, Mar. 2021, Diabetes Obesity and Metabolism, 23(3) (3), 692 - 699, English, International magazine[Refereed]Scientific journal
- BACKGROUND: Recently, a standardized uptake value (SUV) has been used to evaluate bone single-photon emission computed tomography (SPECT). The aim of this study was to investigate quantitative SPECT imaging of uninfected nonunion to compare hypertrophic nonunion and non-hypertrophic nonunion using volume-based parameters. METHODS: We evaluated 23 patients with uninfected nonunion who underwent SPECT acquisition 3 h after an injection of 99mTc-hydroxymethylene diphosphonate or 99mTc-methylene diphosphonate from April 2014 to November 2019. We reconstructed the acquired data and performed voxel-based quantitative analysis using the GI-BONE software. Quantitative parameters, maximum SUV (SUVmax), peak SUV (SUVpeak), and mean SUV (SUVmean) in the high and low uptake areas of nonunion were compared between hypertrophic nonunion and non-hypertrophic nonunion. The contralateral limb was used as a control, and the ratios of the quantitative parameters were calculated. RESULTS: The values for the quantitative parameters (high uptake area/low uptake area, respectively), SUVmax control ratio (12.13 ± 4.95/6.44 ± 4.71), SUVpeak control ratio (11.65 ± 4.58/6.45 ± 4.64), and SUVmean control ratio (11.94 ± 5.03/6.28 ± 4.95) for hypertrophic nonunion were higher than those for non-hypertrophic nonunion (7.82 ± 4.76/3.41 ± 2.09 (p = 0.065/0.12), 7.56 ± 4.51/3.61 ± 2.23 (p = 0.065/0.22), and 7.59 ± 5.18/3.05 ± 1.91 (p = 0.076/0.23)). CONCLUSIONS: SUVmax, SUVpeak, and SUVmean control ratios obtained from bone SPECT images can quantitatively evaluate the biological activity of nonunions and may be an effective evaluation method for treatment decisions, especially the necessity of autologous bone grafting.Feb. 2021, Journal of orthopaedic surgery and research, 16(1) (1), 125 - 125, English, International magazine[Refereed]Scientific journal
- BACKGROUND: Non-curative (debulking) hepatic resection for hepatocellular carcinoma (HCC) is occasionally applied for selected cases with bulky tumors or for oncologic emergency cases; however, the clinical usefulness of this procedure has not yet been fully evaluated. The aim of the present study was to evaluate the patient outcomes of non-curative hepatic resections for HCC using data from bi-annual nationwide surveys conducted in Japan. METHOD: Data of 1084 non-curative hepatic resections for HCC were collected. The patient outcomes were compared with those of curative resections, transcatheter arterial chemoembolization (TACE), and hepatic arterial infusion chemotherapy (HAIC). RESULTS: Patient survival after the non-curative resection was poorer than that after curative resection (P < 0.001) and was especially dismal in cases with extrahepatic tumor spread (lymph node metastasis, peritoneal seeding, or distant metastasis). As compared to cases receiving TACE without surgery, non-curative resections for multiple intrahepatic tumors were applied to cases with advanced tumors with good liver functional reserve. The survival outcomes were significantly more favorable in the TACE group, but the results became similar after propensity score matching of the patients. The survival outcome of patients receiving non-curative resections was better than that of cases treated by HAIC, with median survival times of 26.0 months and 10.0 months, respectively. CONCLUSION: The indications for non-curative hepatic resection in patients with HCC should be judged cautiously, especially in patients with extrahepatic tumor spread. This treatment approach may be beneficial for selected patients with intermediate- or advanced-stage HCC limited in liver and with good liver functional reserve.Feb. 2021, World journal of surgery, 45(2) (2), 607 - 614, English, International magazine[Refereed]Scientific journal
- OBJECTIVES: The 9th International Forum for Liver Magnetic Resonance Imaging (MRI) was held in Singapore in September 2019, bringing together radiologists and allied specialists to discuss the latest developments in and formulate consensus statements for liver MRI, including the applications of gadoxetic acid-enhanced imaging. METHODS: As at previous Liver Forums, the meeting was held over 2 days. Presentations by the faculty on days 1 and 2 and breakout group discussions on day 1 were followed by delegate voting on consensus statements presented on day 2. Presentations and discussions centered on two main meeting themes relating to the use of gadoxetic acid-enhanced MRI in primary liver cancer and metastatic liver disease. RESULTS AND CONCLUSIONS: Gadoxetic acid-enhanced MRI offers the ability to monitor response to systemic therapy and to assist in pre-surgical/pre-interventional planning in liver metastases. In hepatocellular carcinoma, gadoxetic acid-enhanced MRI provides precise staging information for accurate treatment decision-making and follow-up post therapy. Gadoxetic acid-enhanced MRI also has potential, currently investigational, indications for the functional assessment of the liver and the biliary system. Additional voting sessions at the Liver Forum debated the role of multidisciplinary care in the management of patients with liver disease, evidence to support the use of abbreviated imaging protocols, and the importance of standardizing nomenclature in international guidelines in order to increase the sharing of scientific data and improve the communication between centers. KEY POINTS: • Gadoxetic acid-enhanced MRI is the preferred imaging method for pre-surgical or pre-interventional planning for liver metastases after systemic therapy. • Gadoxetic acid-enhanced MRI provides accurate staging of HCC before and after treatment with locoregional/biologic therapies. • Abbreviated protocols for gadoxetic acid-enhanced MRI offer potential time and cost savings, but more evidence is necessary. The use of gadoxetic acid-enhanced MRI for the assessment of liver and biliary function is under active investigation.Feb. 2021, European radiology[Epub ahead of print], English, International magazine[Refereed]Scientific journal
- PURPOSE: To identify predictive factors for truncation artifacts (TAs) in the arterial phase of Gd-EOB-DTPA-enhanced MRI in a multicenter study in Japan. MATERIALS AND METHODS: Data on patient factors (age, sex, weight, presence of viral hepatitis, and other conditions) and imaging parameters (e.g., triggering, voxel size, matrix, k-space ordering, acquisition time, reduction factor, flip angle, fat suppression, field strength, injection rate, and saline volume) were obtained. Univariate and multivariate analyses were performed to investigate the correlation of these parameters. RESULTS: We evaluated 1444 patients from 43 institutions who were scanned using GE, Siemens, Philips, or Toshiba MRI equipment (501, 354, 349, and 240 patients, respectively). The total incidence of TAs was 12.5% (17.2, 3.6, 15.7, and 12.1%, respectively). The matrix [odds ratio (OR) 0.13], flip angle (OR 5.77), use of fat suppression (OR 0.106), and field strength (OR 0.092) used in the Philips equipment significantly increased the incidence of TAs in MRI examination. CONCLUSIONS: The incidence of TAs in the arterial phase is influenced by several patient factors and imaging parameters. Especially, Siemens and Toshiba equipment had a significantly lower frequency of TAs. This indicates that such vendor-specific technology used in the dynamic sequence may have a TA-resistant effect.Springer Science and Business Media LLC, Feb. 2021, Japanese journal of radiology, 39(2) (2), 165 - 177, English, Domestic magazineScientific journal
- Dual-energy computed tomography (DECT) is an imaging technique based on data acquisition at two different energy settings. Recent advances in CT have allowed data acquisitions and simultaneous analyses of X-rays at two energy levels, and have resulted in novel developments in the field of abdominal imaging. The use of low and high X-ray tube voltages in DECT provide fused images that improve the detection of liver tumors owing to the higher contrast-to-noise ratio (CNR) of the tumor compared with the liver. The use of contrast agents in CT scanning improves image quality by enhancing the CNR and signal-to-noise ratio while reducing beam-hardening artifacts. DECT can improve detection and characterization of hepatic abnormalities, including mass lesions. The technique can also be used for the diagnosis of steatosis and iron overload. This article reviews and illustrates the different applications of DECT in liver imaging.MDPI AG, Jan. 2021, Diagnostics (Basel, Switzerland), 11(2) (2), 161 - 161, English, International magazine[Refereed]Scientific journal

- BACKGROUND: Postoperative biliary strictures are commonly related to accidental bile duct injuries or occur at the site of biliary anastomosis. The first-line treatment for benign biliary strictures is endoscopic therapy, which is less invasive and repeatable. However, recanalization for biliary complete obstruction is technically challenging to treat. The present report describes a successful case of treatment by extraluminal recanalization for postoperative biliary obstruction using a transseptal needle. CASE PRESENTATION: A 66-year-old woman had undergone caudal lobectomy for the treatment of hepatocellular carcinoma. The posterior segmental branch of the bile duct was injured and repaired intraoperatively. Three months after the surgery, the patient had developed biliary leakage from the right hepatic bile duct, resulting in complete biliary obstruction. Since intraluminal recanalization with conventional endoscopic and percutaneous approaches with a guidewire failed, extraluminal recanalization using a transseptal needle with an internal lumen via percutaneous approach was performed under fluoroscopic guidance. The left lateral inferior segmental duct was punctured, and an 8-F transseptal sheath was introduced into the ostium of right hepatic duct. A transseptal needle was advanced, and the right hepatic duct was punctured by targeting an inflated balloon that was placed at the end of the obstructed right hepatic bile duct. After confirming successful puncture using contrast agent injected through the internal lumen of the needle, a 0.014-in. guidewire was advanced into the right hepatic duct. Finally, an 8.5-F internal-external biliary drainage tube was successfully placed without complications. One month after the procedure, the drainage tube was replaced with a 10.2-F drainage tube to dilate the created tract. Subsequent endoscopic internalization was performed 5 months after the procedure. At the 1-year follow-up examination, there was no sign of biliary obstruction and recurrence of hepatocellular carcinoma. CONCLUSIONS: Recanalization using a transseptal needle can be an alternative technique for rigid biliary obstruction when conventional techniques fail.Dec. 2020, Surgical case reports, 6(1) (1), 304 - 304, English, International magazine[Refereed]Scientific journal

Abstract We hypothesized that, in discrimination between benign and malignant parotid gland tumors, high diagnostic accuracy could be obtained with a small amount of imbalanced data when anomaly detection (AD) was combined with deep leaning (DL) model and the L2-constrained softmax loss. The purpose of this study was to evaluate whether the proposed method was more accurate than other commonly used DL or AD methods. Magnetic resonance (MR) images of 245 parotid tumors (22.5% malignant) were retrospectively collected. We evaluated the diagnostic accuracy of the proposed method (VGG16-based DL and AD) and that of classification models using conventional DL and AD methods. A radiologist also evaluated the MR images. ROC and precision-recall (PR) analyses were performed, and the area under the curve (AUC) was calculated. In terms of diagnostic performance, the VGG16-based model with the L2-constrained softmax loss and AD (local outlier factor) outperformed conventional DL and AD methods and a radiologist (ROC-AUC = 0.86 and PR-ROC = 0.77). The proposed method could discriminate between benign and malignant parotid tumors in MR images even when only a small amount of data with imbalanced distribution is available.[Refereed]Scientific journal - Springer Science and Business Media LLC, Dec. 2020, Scientific Reports, 10(1) (1), 17532
Abstract This study aimed to develop and validate computer-aided diagnosis (CXDx) system for classification between COVID-19 pneumonia, non-COVID-19 pneumonia, and the healthy on chest X-ray (CXR) images. From two public datasets, 1248 CXR images were obtained, which included 215, 533, and 500 CXR images of COVID-19 pneumonia patients, non-COVID-19 pneumonia patients, and the healthy samples, respectively. The proposed CADx system utilized VGG16 as a pre-trained model and combination of conventional method and mixup as data augmentation methods. Other types of pre-trained models were compared with the VGG16-based model. Single type or no data augmentation methods were also evaluated. Splitting of training/validation/test sets was used when building and evaluating the CADx system. Three-category accuracy was evaluated for test set with 125 CXR images. The three-category accuracy of the CAD system was 83.6% between COVID-19 pneumonia, non-COVID-19 pneumonia, and the healthy. Sensitivity for COVID-19 pneumonia was more than 90%. The combination of conventional method and mixup was more useful than single type or no data augmentation method. In conclusion, this study was able to create an accurate CADx system for the 3-category classification. Source code of our CADx system is available as open source for COVID-19 research.[Refereed]Scientific journal - PURPOSE: Hierarchical clustering (HC), an unsupervised machine learning (ML) technique, was applied to multi-parametric MR (mp-MR) for prostate cancer (PCa). The aim of this study is to demonstrate HC can diagnose PCa in a straightforward interpretable way, in contrast to deep learning (DL) techniques. METHODS: HC was constructed using mp-MR including intravoxel incoherent motion, diffusion kurtosis imaging, and dynamic contrast-enhanced MRI from 40 tumor and normal tissues in peripheral zone (PZ) and 23 tumor and normal tissues in transition zone (TZ). HC model was optimized by assessing the combinations of several dissimilarity and linkage methods. Goodness of HC model was validated by internal methods. RESULTS: Accuracy for differentiating tumor and normal tissue by optimal HC model was 96.3% in PZ and 97.8% in TZ, comparable to current clinical standards. Relationship between input (DWI and permeability parameters) and output (tumor and normal tissue cluster) was shown by heat maps, consistent with literature. CONCLUSION: HC can accurately differentiate PCa and normal tissue, comparable to state-of-the-art diffusion based parameters. Contrary to DL techniques, HC is an operator-independent ML technique producing results that can be interpreted such that the results can be knowledgeably judged.Elsevier BV, Dec. 2020, Magnetic Resonance Imaging, 74, 90 - 95, English, International magazine[Refereed]Scientific journal

- PURPOSE: To evaluate the efficacy and safety of transcatheter arterial embolization (TAE) for pseudoaneurysms occurring secondary to pancreatitis or because of leakage of pancreatic juice after pancreatectomy. MATERIALS AND METHODS: This retrospective study included 42 consecutive patients (38 males and 4 females; mean age, 60 years; range, 33-80 years) who underwent TAE for bleeding visceral artery pseudoaneurysms between March 2004 and December 2018. The technical and clinical success rates, incidence of recurrent bleeding, complications, including pancreatitis, and overall survival after TAE were evaluated. RESULTS: Of the 42 enrolled patients, 23 had bleeding due to a complication of pancreatectomy and 19 had bleeding as a complication of pancreatitis. TAE with N-butyl cyanoacrylate (NBCA) or NBCA plus microcoils recurrent bleeding or inability to control bleeding was 15.8% (3 of 19) following TAE with NBCA and 17.4% (4 of 23) following TAE with coils. No clinically significant ischemic events of the pancreas or duodenum were observed in the embolized areas. Serum amylase did not increase compared with the initial levels after any of the procedures. At 30 days after TAE, 32 patients were alive. CONCLUSION: TAE has a high success rate for the management of hemorrhage, with few complications. The procedure appears to be safe and effective for pseudoaneurysms associated with either pancreatitis or pancreatectomy.Sep. 2020, Cancers, 12(10) (10), 2733 - 2733, English, International magazine[Refereed]Scientific journal
- PURPOSE: Accurate prediction of post-hepatectomy liver failure (PHLF) is important in advanced hepatocellular carcinoma (HCC). We aimed to retrospectively evaluate the utility of gadoxetic acid-enhanced MRI for predicting PHLF in patients who underwent anatomic hepatectomy for HCC with portal vein invasion. METHODS: Forty-one patients (32 men, 9 women) were included. Hepatobiliary-phase MR images were acquired 20 min after injection of gadoxetic acid using a 3D fat-suppressed T1-weighted spoiled gradient-echo sequence. Liver-spleen ratio (LSR), remnant hepatocellular uptake index (rHUI), and HUI were calculated. The severity of PHLF was defined according to the International Study Group of Liver Surgery. Differences in LSR between the resected liver and the remnant liver, and HUI and rHUI/HUI between no/mild and severe PHLF were compared using the Wilcoxon signed-rank test and Wilcoxon rank-sum test, respectively. Univariate and multivariate logistic regression analyses were performed to identify predictors of severe PHLF. Areas under the receiver operating characteristic curves (AUCs) of rHUI and rHUI/HUI were calculated for predicting severe PHLF. RESULTS: Nine patients developed severe PHLF. LSR of the remnant liver was significantly higher than that of the resected liver (P < 0.001). Severe PHLF demonstrated significantly lower rHUI (P < 0.001) and rHUI/HUI (P < 0.001) compared with no/mild PHLF. Multivariate logistic regression analysis showed that decreased rHUI (P = 0.012, AUC=0.885) and rHUI/HUI (P = 0.002, AUC=0.852) were independent predictors of severe PHLF. CONCLUSION: Gadoxetic acid-enhanced MRI can be a promising noninvasive examination for assessing global and regional liver function, allowing estimation of the functional liver remnant and accurate prediction of severe PHLF before hepatic resection.Sep. 2020, European journal of radiology, 130, 109189 - 109189, English, International magazine[Refereed]Scientific journal

- OBJECTIVE: Positron emission tomography (PET)-computed tomography has revealed that metformin promotes the intestinal accumulation of [18F]fluorodeoxyglucose (FDG), a nonmetabolizable glucose derivative. It has remained unknown, however, whether this accumulation occurs in the wall or intraluminal space of the intestine. We here addressed this question with the use of [18F]FDG PET-MRI, a recently developed imaging method with increased accuracy of registration and high soft-tissue contrast. RESEARCH DESIGN AND METHODS: Among 244 individuals with type 2 diabetes who underwent PET-MRI, we extracted 24 pairs of subjects matched for age, BMI, and HbA1c level who were receiving treatment with metformin (metformin group) or were not (control group). We evaluated accumulation of [18F]FDG in different portions of the intestine with both a visual scale and measurement of maximum standardized uptake value (SUVmax), and such accumulation within the intestinal wall or lumen was discriminated on the basis of SUVmax. RESULTS: SUVmax of the jejunum, ileum, and right or left hemicolon was greater in the metformin group than in the control group. [18F]FDG accumulation in the ileum and right or left hemicolon, as assessed with the visual scale, was also greater in the metformin group. SUVmax for the intraluminal space of the ileum and right or left hemicolon, but not that for the intestinal wall, was greater in the metformin group than in the control group. CONCLUSIONS: Metformin treatment was associated with increased accumulation of [18F]FDG in the intraluminal space of the intestine, suggesting that this drug promotes the transport of glucose from the circulation into stool.Jul. 2020, Diabetes Care, 43(7) (7), 1 - 7, English, International magazine[Refereed]Scientific journal
- The usefulness of sparse-sampling CT with deep learning-based reconstruction for detection of metastasis of malignant ovarian tumors was evaluated. We obtained contrast-enhanced CT images (n = 141) of ovarian cancers from a public database, whose images were randomly divided into 71 training, 20 validation, and 50 test cases. Sparse-sampling CT images were calculated slice-by-slice by software simulation. Two deep-learning models for deep learning-based reconstruction were evaluated: Residual Encoder-Decoder Convolutional Neural Network (RED-CNN) and deeper U-net. For 50 test cases, we evaluated the peak signal-to-noise ratio (PSNR) and structural similarity (SSIM) as quantitative measures. Two radiologists independently performed a qualitative evaluation for the following points: entire CT image quality; visibility of the iliac artery; and visibility of peritoneal dissemination, liver metastasis, and lymph node metastasis. Wilcoxon signed-rank test and McNemar test were used to compare image quality and metastasis detectability between the two models, respectively. The mean PSNR and SSIM performed better with deeper U-net over RED-CNN. For all items of the visual evaluation, deeper U-net scored significantly better than RED-CNN. The metastasis detectability with deeper U-net was more than 95%. Sparse-sampling CT with deep learning-based reconstruction proved useful in detecting metastasis of malignant ovarian tumors and might contribute to reducing overall CT-radiation exposure.MDPI AG, Jun. 2020, Applied Sciences, 10(13) (13), 4446 - 4446Scientific journal
- PURPOSE: To evaluate the mid-term outcomes of transarterial embolization (TAE) for type II endoleak after endovascular abdominal aortic aneurysm repair (EVAR) and investigate the predictors of sac enlargement after embolization. MATERIALS AND METHODS: We conducted a retrospective analysis of 55 patients [48 men and 7 women, median age 79.0 (interquartile ranges 74-82) years] who underwent TAE for type II endoleak from 2010 to 2018. The aneurysmal sac enlargement, endoleaks, aneurysm-related adverse event rate, and reintervention rate were evaluated. Patients' characteristics and clinical factors were evaluated for their association with sac enlargement. RESULTS: Fifty-five patients underwent TAE with technical success and were subsequently followed for a median of 636 (interquartile ranges 446-1292) days. The freedom from sac enlargement rates at 1, 3, and 5 years was 73.2%, 32.0%, and 26.7%, respectively. After initial TAE, the recurrent type II, delayed type I, and occult type III endoleak were identified in 39 (71%), 5 (9%), and 3 (5%) patients, respectively. Although a patient had aorto-duodenal fistula, there was no aneurysm-related death. The freedom from reintervention rates was 84.6%, 35.7%, and 17.0%, respectively. In the multivariate analysis, sac diameter > 55 mm at initial TAE (hazard ratios, 3.23; 95% confidence intervals, 1.22-8.58; P < 0.05) was a significant predictor of sac enlargement. CONCLUSION: TAE for type II endoleak was not effective in preventing sac enlargement, and reinterventions were required among the mid-term follow-up. The sac diameter > 55 mm at initial TAE was a significant predictor of sac enlargement.May 2020, Cardiovascular and interventional radiology, 43(5) (5), 696 - 705, English, International magazine[Refereed]Scientific journal
- PURPOSE: To assess the utility of whole-aorta CT angiography (CTA) with 15 mL contrast material (CM) on time-resolved imaging for endovascular abdominal aortic repair (EVAR). METHODS: Twenty-six patients with a high-risk of post-contrast acute kidney injury (PC-AKI) underwent CTA with 15 mL CM using temporal maximum intensity projection (tMIP-CTA) generated from time-resolved imaging. The aortoiliac CT values were measured. Two observers measured the arterial diameters in unenhanced CT and tMIP-CTA images, and image quality was evaluated on a 5-point scale. The presence of the accessory renal artery, inferior mesenteric artery (IMA) occlusion, and instructions for use (IFU) of EVAR were evaluated. RESULTS: CT examinations were successfully performed, and no patients developed PC-AKI. The mean CT values of the whole aorta were 267.5 ± 51.4 HU, which gradually decreased according to the distal levels of the aorta. Bland-Altman analysis revealed excellent agreement for the external arterial diameter measurements between unenhanced CT and tMIP-CTA. Excellent interobserver agreement was achieved for the measurements of the external (ICCs, 0.910-0.992) and internal arterial diameters (ICCs, 0.895-0.993). Excellent or good overall image quality was achieved in 24 (92 %) patients. The presence of the accessory renal artery, IMA occlusion and the assessment of IFU were in 100 % agreement. Multivariate analysis revealed aortic volume as the most significant independent factor associated with strong aortic enhancement (p = 0.004). CONCLUSIONS: Whole-aorta tMIP-CTA on time-resolved imaging is useful for maintaining contrast enhancement and image quality for EVAR planning, and can substantially reduce the amount of CM.May 2020, European journal of radiology, 126, 108861 - 108861, English, International magazine[Refereed]Scientific journal
- OBJECTIVES: This study aimed to evaluate the diagnostic performance of the lung zero-echo time (ZTE) sequence in FDG PET/MRI for detection and differentiation of lung lesions in oncologic patients in comparison with conventional two-point Dixon-based MR imaging. METHODS: In this single-institution retrospective study approved by the institutional review board, 209 patients with malignancies (97 men and 112 women; age range, 17-89 years; mean age, 66.5 ± 12.9 years) underwent 18F-FDG PET/MRI between August 2017 and August 2018, with diagnostic Dixon and ZTE under respiratory gating acquired simultaneously with PET. Image analysis was performed for PET/Dixon and PET/ZTE fused images by two readers to assess the detectability and differentiation of lung lesions. The reference standard was pathological findings and/or the data from a chest CT. The detection and differentiation abilities were evaluated for all lesions and subgroups divided by lesion size and maximum standardized uptake value (SUVmax). RESULTS: Based on the reference standard, 227 lung lesions were identified in 113 patients. The detectability of PET/ZTE was significantly better than that of PET/Dixon for overall lesions, lesions with a SUVmax less than 3.0 and lesions smaller than 4 mm (p < 0.01). The diagnostic performance of PET/ZTE was significantly better than that of PET/Dixon for overall lesions and lesions smaller than 4 mm (p < 0.01). CONCLUSIONS: ZTE can improve diagnostic performance in the detection and differentiation of both FDG-avid and non-FDG-avid lung lesions smaller than 4 mm in size, yielding a promising tool to enhance the utility of FDG PET/MRI in oncology patients with lung lesions. KEY POINTS: • The detection rate of PET/ZTE for lesions with a SUVmax of less than 1.0 was significantly better than that of PET/Dixon. • The performance for differentiation of PET/ZTE for lesions that were even smaller than 4 mm in size were significantly better than that of PET/Dixon. • Inter-rater agreement of PET/ZTE for the differentiation of lesions less than 4 mm in size was substantial and better than that of PET/Dixon.Apr. 2020, European Radiology, 30(9) (9), 4995 - 5003, English, International magazine[Refereed]Scientific journal
- BACKGROUND: Although total tumour volume (TTV) may have prognostic value for hepatic resection in certain solid cancers, its importance in colorectal liver metastases (CRLM) remains unexplored. This study investigated its prognostic value in patients with resectable CRLM. METHOD: This was a retrospective review of patients who underwent hepatic resection for CRLM between 2008 and 2017 in a single institution. TTV was measured from CT images using three-dimensional construction software; cut-off values were determined using receiver operating characteristic (ROC) curve analyses. Potential prognostic factors, overall survival (OS) and recurrence-free survival (RFS) were determined using multivariable and Kaplan-Meier analyses. RESULTS: Some 94 patients were included. TTV cut-off values for OS and RFS were 100 and 10 ml respectively. Right colonic primary tumours, primary lymph node metastasis and bilobar liver metastasis were included in the multivariable analysis of OS; a TTV of 100 ml or above was independently associated with poorer OS (hazard ratio (HR) 6·34, 95 per cent c.i. 2·08 to 17·90; P = 0·002). Right colonic primary tumours and primary lymph node metastasis were included in the RFS analysis; a TTV of 10 ml or more independently predicted poorer RFS (HR 1·90, 1·12 to 3·57; P = 0·017). The 5-year OS rate for a TTV of 100 ml or more was 41 per cent, compared with 67 per cent for a TTV below 100 ml (P = 0·006). Corresponding RFS rates with TTV of 10 ml or more, or less than 10 ml, were 14 and 58 per cent respectively (P = 0·009). A TTV of at least 100 ml conferred a higher rate of unresectable initial recurrences (12 of 15, 80 per cent) after initial hepatic resection. CONCLUSION: TTV was associated with RFS and OS after initial hepatic resection for CRLM; TTV of 100 ml or above was associated with a higher rate of unresectable recurrence.Apr. 2020, BJS open, 4(3) (3), 456 - 466, English, International magazine[Refereed]
- BACKGROUND: Differentiation between inflammation and fibrosis is an important clinical distinction in patients with chronic liver disease, which has been difficult so far with MR elastography. PURPOSE: To investigate whether dual-frequency MR elastography can estimate necroinflammation of the liver and improve diagnostic performance for the staging of liver fibrosis. STUDY TYPE: Retrospective. SUBJECTS: In all, 30 patients (14 males, 16 females) with chronic liver disease. FIELD STRENGTH/SEQUENCE: 1.5T/dual-frequency MR elastography at 60-Hz and 80-Hz vibration frequencies. [Correction added on November 12, 2019, after first online publication: The field strength in the preceding sentence was corrected.] ASSESSMENT: Necroinflammation activity and fibrosis were assessed using the METAVIR scoring system. Stiffness values at 60-Hz (G60-Hz ) and 80-Hz (G80-Hz ) were obtained with an MR elastogram. The difference value between G80-Hz and G60-Hz (ΔG) was calculated. Four values (G60-Hz , G80-Hz , G60-Hz - ΔG, and G80-Hz + ΔG) were generated to estimate necroinflammation and fibrosis. STATISTICAL TESTS: The ΔG were correlated with necroinflammation activity grade and fibrosis stage using Spearman's rank correlation. Diagnostic performance of the four values for necroinflammation activity grade and fibrous stage was assessed by using area under the receiver operating characteristic curve (AUC). RESULTS: The mean value of G80-Hz (6.23 ± 3.67 kPa) was significantly higher than that of G60-Hz (5.27 ± 3.14 kPa) (P < 0.0001). The ΔG demonstrated a strong correlation with necroinflammation grade (ρ = 0.625, P < 0.001) and no correlation with fibrosis stage (ρ = 0.306, P = 0.113). The AUC of the G80-Hz and G80-Hz + ΔG showed higher accuracy for necroinflammation, and optimal cutoff values yielded better discrimination of ≥A1, ≥A2, and = A3. The AUC demonstrated that all the generated values had high diagnostic performance (≥0.87 for all) for fibrosis. DATA CONCLUSION: Dual-frequency MR elastography shows potential in estimating necroinflammation of the liver and may improve diagnostic performance for staging liver fibrosis.

- BACKGROUND: The present study aimed to assess the clinical features of patients who received lenvatinib treatment for unresectable hepatocellular carcinoma (HCC). METHODS: The clinical characteristics, adverse events, and radiological responses were evaluated for 51 consecutive patients. RESULTS: Of the study subjects, 37 patients had Child-Pugh class A (CPA) liver function, and 14 patients had Child-Pugh class B (CPB) liver function. The overall response rates in the CPA and CPB groups were 42.9% and 25.0%, respectively, and disease control rates were 82.9% and 83.3%, respectively, without significant difference (p = 0.2621 and 0.9697). There was no significant difference between CPA and CPB groups regarding the incidence of adverse events, except for hepatic coma. No significant difference was observed in the relative dose intensity between the CPA and CPB groups, for the first month, 1-2 months, or 2-3 months (p = 0.2368, 0.9368, and 0.9293). CONCLUSION: The comparable outcomes between the CPA and CPB groups suggest the acceptability of lenvatinib treatment in patients with impaired liver function, at least in the acute phase. With careful follow-up, the dose can be relatively intensified, even in patients with impaired liver function and this may contribute to offering comparable treatment.Mar. 2020, HPB : the official journal of the International Hepato Pancreato Biliary Association[Epub ahead of print], 22(10) (10), 1450 - 1456, English, International magazineScientific journal

- OBJECTIVES: The 8th International Forum for Liver Magnetic Resonance Imaging (MRI), held in Basel, Switzerland, in October 2017, brought together clinical and academic radiologists from around the world to discuss developments in and reach consensus on key issues in the field of gadoxetic acid-enhanced liver MRI since the previous Forum held in 2013. METHODS: Two main themes in liver MRI were considered in detail at the Forum: the use of gadoxetic acid for contrast-enhanced MRI in patients with liver cirrhosis and the technical performance of gadoxetic acid-enhanced liver MRI, both opportunities and challenges. This article summarises the expert presentations and the delegate voting on consensus statements discussed at the Forum. RESULTS AND CONCLUSIONS: It was concluded that gadoxetic acid-enhanced MRI has higher sensitivity for the diagnosis of hepatocellular carcinoma (HCC), when compared with multidetector CT, by utilising features of hyperenhancement in the arterial phase and hypointensity in the hepatobiliary phase (HBP). Recent HCC management guidelines recognise an increasing role for gadoxetic acid-enhanced MRI in early diagnosis and monitoring post-resection. Additional research is needed to define the role of HBP in predicting microvascular invasion, to better define washout during the transitional phase in gadoxetic acid-enhanced MRI for HCC diagnosis, and to reduce the artefacts encountered in the arterial phase. Technical developments are being directed to shortening the MRI protocol for reducing time and patient discomfort and toward utilising faster imaging and non-Cartesian free-breathing approaches that have the potential to improve multiphasic dynamic imaging. KEY POINTS: • Gadoxetic acid-enhanced MRI provides higher diagnostic sensitivity than CT for diagnosing HCC. • Gadoxetic acid-enhanced MRI has roles in early-HCC diagnosis and monitoring post-resection response. • Faster imaging and free-breathing approaches have potential to improve multiphasic dynamic imaging.Jan. 2020, European radiology, 30(1) (1), 370 - 382, English, International magazine[Refereed]
- Introduction: The underlying mechanism involved in the recurrence of hepatoma after hepatic arterial embolization (HAE) is not adequately examined. An immunosuppressive cytokine, transforming growth factor β1 (TGF-β1), can lead to tumor progression and is affected by hypoxia in various cancers. The study aimed to assess the effect of HAE on the expression of TGF-β1 in a rat hepatoma model. Methods: Sprague-Dawley rats bearing N1S1 hepatoma cells underwent HAE (HAE group, n = 5) or sham treatment (sham group, n = 4). The animals were euthanized at 48 h, and liver tissues were harvested. Immunohistochemistry (IHC) and quantitative polymerase chain reaction (qPCR) were performed to compare the expression of TGF-β1 and hypoxia-inducible factor 1α (HIF-1α) between the HAE and sham groups. In vitro experiments with the N1S1 cell line were also performed under normoxic (21% O2) or hypoxic (1% O2) conditions for 48 h, and the expression of TGF-β1 and HIF-1α was assessed with western blotting and enzyme-linked immunosorbent assay. Statistical data comparisons were performed by Student t test. Results: IHC showed that both the TGF-β1-positive and HIF-1α-positive tumor peripheral areas were larger in the HAE group (6.59 ± 2.49 and 10.26 ± 4.14%; p < 0.001, respectively) than in the sham group (0.34 ± 0.41 and 0.40 ± 0.84% respectively). Similarly, qPCR showed that the mRNA expression levels of TGF-β1 and HIF-1α were higher (1.95 ± 0.38-fold and 1.62 ± 0.37-fold; p < 0.001 and p = 0.002, respectively) in the HAE group than those in the sham group. TGF-β1 expression was suppressed when HIF-1α inhibitors were added (p = 0.001), and HIF-1α expression was upregulated when exogenous TGF-β1 was added (p = 0.033) in N1S1 cells. Conclusion: HAE enhanced local TGF-β1 expression in a rat hepatoma model. In vitro experiments suggest that HAE-induced hypoxic stress may trigger the interdependent expression of TGF-β1 and HIF-1α.Jan. 2020, Liver cancer, 9(1) (1), 63 - 72, English, International magazine[Refereed]Scientific journal

- In the 20th Nationwide Follow-up Survey of Primary Liver Cancer in Japan, data from 21 075 new patients and 40 769 previously followed patients were compiled from 544 institutions over a 2-year period from 1 January 2008 to 31 December 2009. Compared with the previous 19th survey, the population of patients with hepatocellular carcinoma (HCC) was older at the time of clinical diagnosis, included more female patients, included more patients with non-B non-C HCC, had smaller tumor diameters and more frequently received radiofrequency ablation as local ablation therapy. Cumulative survival rates were calculated for HCC, intrahepatic cholangiocarcinoma, and combined hepatocellular cholangiocarcinoma (combined HCC and intrahepatic cholangiocarcinoma) by treatment type and by background characteristics for patients newly registered between 1998 and 2009 whose final outcome was survival or death. Cumulative survival rates for HCC were calculated by dividing patients by combinations of background factors (number of tumors, tumor diameter, and Child-Pugh grade) and by treatment types (hepatectomy, local ablation therapy, and transcatheter arterial chemoembolization). Cumulative survival rates and median overall survival in patients treated by resection, transcatheter arterial chemoembolization, and local ablation therapy were calculated. The same values were also calculated by the registration date by dividing patients newly registered between 1978 and 2009 into four time period groups . The results of the analysis show that the prognosis of HCC is improving dramatically. It is expected that the data obtained from this nationwide follow-up survey will contribute to advancing clinical research, including the design of clinical trials, as well as the treatment strategy of primary liver cancer in the clinical practice setting.Jan. 2020, Hepatology research : the official journal of the Japan Society of Hepatology, 50(1) (1), 15 - 46, English, International magazine[Refereed]Scientific journal
- BACKGROUND: The impact of a wide surgical margin on the outcome of patients with hepatocellular carcinoma (HCC) has not been evaluated in relation to the type of liver resection performed, anatomical or non-anatomical. The aim of this study was to evaluate the impact of surgical margin status on outcomes in patients undergoing anatomical or non-anatomical resection for solitary HCC. METHODS: Data from patients with solitary HCC who had undergone non-anatomical partial resection (Hr0 group) or anatomical resection of one Couinaud segment (HrS group) between 2000 and 2007 were extracted from a nationwide survey database in Japan. Overall and recurrence-free survival associated with the surgical margin status and width were evaluated in the two groups. RESULTS: A total of 4457 patients were included in the Hr0 group and 3507 in the HrS group. A microscopically positive surgical margin was associated with poor overall survival in both groups. A negative but 0-mm surgical margin was associated with poorer overall and recurrence-free survival than a wider margin only in the Hr0 group. In the HrS group, the width of the surgical margin was not associated with patient outcome. CONCLUSION: Anatomical resection with a negative 0-mm surgical margin may be acceptable. Non-anatomical resection with a negative 0-mm margin was associated with a less favourable survival outcome.Jan. 2020, The British journal of surgery, 107(1) (1), 113 - 120, English, International magazine[Refereed]

- Response Evaluation Criteria in Solid Tumors (RECIST) is inappropriate to assess the direct effects of treatment on hepatocellular carcinoma (HCC) by locoregional therapies, such as radiofrequency ablation and transarterial chemoembolization. Therefore, establishment of response evaluation criteria solely devoted to HCC is needed in clinical practice, as well as in clinical trials of HCC treatment, such as systemic therapies, which cause necrosis of the tumor. Response Evaluation Criteria in Cancer of the Liver (RECICL) was revised in 2019 by the Liver Cancer Study Group of Japan based on the 2015 version of RECICL, which was commonly used in Japan. The major revised points of the RECICL 2019 are as follows: (i) CEA and CA19-9 have been newly added as tumor markers that should be recorded for use as criteria in the response evaluation for intrahepatic cholangiocarcinoma; (ii) the criteria now state that the details of molecular targeted therapy should be specified; and (iii) specific methods for overall evaluation are now described. Also, as an assessment of overall TE4 requires that TE4 is achieved in all nodules (even non-target lesions), the same calculation methods described above are used. We hope this new treatment response criteria, RECICL, proposed by the Liver Cancer Study Group of Japan will benefit the HCC treatment response evaluation in the setting of daily clinical practice and clinical trials as well, not only in Japan, but also internationally.Sep. 2019, Hepatology research : the official journal of the Japan Society of Hepatology, 49(9) (9), 981 - 989, English, International magazine[Refereed]Scientific journal

- A Vesical Imaging-Reporting and Data System (VI-RADS) based on multiparametric magnetic resonance imaging (mp-MRI) was developed to provide accurate information for the diagnosis of muscle-invasive bladder cancers (MIBCs). In this study we evaluated the interobserver agreement and diagnostic performance of VI-RADS. We retrospectively evaluated data for 74 consecutive patients with bladder cancer who had undergone mp-MRI before transurethral resection in a single institution from January 2010 to August 2018. Five readers assessed the probability of the presence of MIBC using VI-RADS scores. The interobserver agreement was assessed by measuring intraclass correlation coefficients (ICCs). Receiver operating characteristic (ROC) analysis was used to evaluate the MIBC diagnostic performance. The area under the ROC curve (AUC) was estimated for ordinal score assessments. Our study demonstrated that interobserver agreement was excellent among five readers (ICC 0.85, 95% confidence interval 0.80-0.89) and the diagnostic performance of VI-RADS was represented as a pooled AUC of 0.90 (95% confidence interval 0.87-0.93). PATIENT SUMMARY: We evaluated the interobserver agreement and diagnostic performance of a new scoring system based on magnetic resonance imaging called a Vesical Imaging-Reporting and Data System (VI-RADS) for muscle-invasive bladder cancer. Our results indicate that VI-RADS is suitable as a comprehensive tool for appropriate treatment planning for patients with bladder cancer.Jul. 2019, European urology, 76(1) (1), 54 - 56, English, International magazine[Refereed]Scientific journal
- PURPOSE: To evaluate the advantages of intraprocedural CT during adrenal venous sampling (AVS) to confirm accurate catheterization of the right adrenal vein (RAV). MATERIALS AND METHODS: This single-institution study included 106 patients (mean age 52.4 years; range 28-74 years) with primary aldosteronism who performed contrast-enhanced CT (CECT) before AVS following AVS between January 2011 and March 2018. After catheterization of the RAV under fluoroscopic guidance, unenhanced CT images were obtained to confirm catheter position on unified CT angiography system. Catheter repositioning was performed when the catheter was inaccurately positioned. Venography findings were classified into two groups: (1) presumably cannulated in the RAV (presumed RAV group) and (2) obscured visualization of the RAV because of collateral vessels (obscured RAV group). Success rates of AVS were compared using Fisher's exact test. RESULTS: The overall success of AVS was achieved in 104 patients (98.1%). Catheter was deviated into the IVC during intraprocedural CT in four patients. Fourteen patients (14.0%) required catheter repositioning by intraprocedural CT images, and accurate catheterization in the RAV was eventually accomplished. The success rate of AVS was significantly higher in the presumed RAV group (90.1% [73/81]) than that in the obscured RAV group (68.4% [13/19]) (p = 0.024). If intraprocedural CT was not acquired during AVS, the success rate of AVS would have been significantly lower (84.9% [90/106]) compared with that use of intraprocedural CT (98.1% [104/106]) (p < 0.001). CONCLUSIONS: Intraprocedural unenhanced CT by referring to the preprocedural CECT before AVS enables the confirmation of accurate catheterization of the RAV.

- PURPOSE: To assess the safety and efficacy of transarterial embolization (TAE) and to evaluate the utility of contrast-enhanced computed tomography (CE-CT) for life-threatening spontaneous retroperitoneal hemorrhage (SRH). METHODS: Nineteen patients underwent TAE following CE-CT for life-threatening SRH. CE-CT and angiographic findings, technical successes, and clinical successes were evaluated. The diagnostic performance of CE-CT for the detection of active bleeding arteries was also assessed by two independent readers. RESULTS: Active extravasation of contrast material was accurately observed in 78.9‒84.2% of the patients on CE-CT. Angiograms revealed active extravasation in 37 arteries of 15 patients (78.9%), and 4 patients showed no sign of active bleeding. Sensitivity, positive predictive value, and accuracy rate of CE-CT for the detection of active bleeding vessels was 59.5%, 62.9‒71.0% and 55.6‒60.0% respectively. The successful embolization of 48 intended arteries was achieved in all the patients, including empirical TAE in four patients. Hemodynamic stabilization was achieved in 17 patients (89.5%) with a significant decrease in transfusion (p < 0.001). CONCLUSION: TAE is a technically safe and clinically effective treatment method for life-threatening SRH. CE-CT has moderate capability for accurate identification of active bleeding arteries. TAE including arteries that potentially distribute anatomic territory of the hematoma is essential.Apr. 2019, Japanese journal of radiology, 37(4) (4), 328 - 335, English, Domestic magazine[Refereed]Scientific journal
- PURPOSE: To evaluate the incidence of type II endoleak (EL-II) and aneurysm enlargement after endovascular aneurysm repair (EVAR) using the Endurant stent graft in patients with abdominal aortic aneurysm (AAA) with occluded inferior mesenteric artery (IMA). MATERIALS AND METHODS: Between 2012 and 2017, 103 patients who underwent EVAR using the Endurant stent graft for AAA with occluded IMA (50 patients with prophylactic embolized IMA and 53 with spontaneous occluded IMA) were retrospectively reviewed. The incidence of EL-II and aneurysm enlargement was evaluated. Predictive factors for persistent EL-II were evaluated based on patient characteristics, preprocedural anatomical characteristics, intraprocedural details, and postprocedural complications. RESULTS: Incidence rates of early EL-II and persistent EL-II were 6.8% (7/103 patients) and 4.9% (5/103 patients), respectively. Aneurysm enlargement was found in 10 patients (9.7%), including all 5 patients with persistent EL-II, 3 with de novo EL-II, and 2 with no EL-II. The rates of freedom from aneurysm enlargement at 1, 2, and 3 years were 98.7%, 97.0%, and 93.1% for the group without persistent EL-II, and 80.0%, 60.0%, and 20.0% for the group with persistent EL-II (p < 0.001), respectively. The maximum aneurysm diameter (odds ratio (OR), 1.16; 95% confidence interval (CI), 1.01-1.34; p = 0.0362) and the number of patent lumbar arteries (OR, 2.72; 95% CI, 1.07-6.90; p = 0.0357) were predictive of persistent EL-II. CONCLUSIONS: The incidence of EL-II after EVAR using the Endurant stent graft for AAA with occluded IMA was low, but most early EL-II persisted and resulted in aneurysm enlargement.

- AIM: To investigate whether iodine density measurements from contrast-enhanced dual-energy computed tomography (CT) data can non-invasively stage liver fibrosis. METHODS: This single-center, prospective study was approved by our IRB with written informed consent. Forty-seven consecutive patients (26 men and 21 women; mean age, 63.1 years) with chronic liver disease underwent contrast-enhanced dual-energy CT of the liver (non-contrast, arterial, portal venous, and equilibrium phase images), followed by liver biopsy. Iodine density of liver and aorta were obtained by two independent observers. Iodine uptake of the liver (Δ Liver), representing the difference in iodine density between equilibrium phase and non-contrast images, was calculated and normalized by aorta (Δ Liver/Aorta). We accounted for contrast agent distribution volume by using hematocrit level. Accuracy of iodine density measurements for staging liver fibrosis was assessed by using receiver operating characteristic (ROC) curves. Multivariate linear regression analysis was used to assess the impact of independent variables (liver fibrosis stage and patient-related confounders) on iodine uptake. RESULTS: The Δ Liver/Aorta significantly increased and moderately correlated with METAVIR liver fibrosis stage (ρ = 0.645, P < 0.001). Areas under the ROC curve ranged from 0.795 to 0.855 for discriminating each liver fibrosis score (≥F1-F4). METAVIR fibrosis stage was the most significant independent factor associated with Δ Liver (P = 0.005) and Δ Liver/Aorta (P < 0.001). CONCLUSION: Hepatic extracellular volume fraction with contrast-enhanced dual-energy CT can non-invasively stage liver fibrosis in chronic liver diseases. This technique could prove useful for monitoring disease progression and treatment response, potentially reducing the need for liver biopsy.Nov. 2018, Hepatol Res, 48(12) (12), 1008 - 1019, English, International magazine[Refereed]Scientific journal

- Introduction: To assess the correlation among 18F-FDG uptake, Glut1, pStat1 and pStat3, and to investigate the relationship between the prognosis and 18F-FDG uptake and these molecular markers in surgically resected non-small cell lung cancer (NSCLC) patients. Results: Knockdown of Glut1 led to a significant increase in pStat1 expression. Glut1 expression positively correlated with the SUVmax, SUVmean, and TLG significantly (P<0.001). pStat3 expression negatively correlated with all PET parameters significantly (P<0.001). pStat1 had positive weak correlations with the SUVmax and SUVmean. All PET parameters and Glut1 were significantly associated with DFS (P<0.05). TLG, MTV, Glut1 and pStat1 were significantly associated with OS (P<0.05). Conclusion: pStat3 and Glut1 may be associated with 18F-FDG uptake mechanism. TLG, MTV, and Glut1 may be independent prognostic factors. Methods: The SUVmax, SUVmean, MTV and TLG of primary lesions were calculated in 140 patients. The expressions of Glut1 and Stat pathway proteins in NSCLC cell lines were examined by immune blots. Excised tumor tissue was analyzed by immunohistochemistry. OS and DFS were evaluated by the Kaplan-Meier method. The difference in survival between subgroups was analyzed by log-rank test. The prognostic significance of clinicopathological, molecular and PET parameters was assessed by Cox proportional hazard regression analysis.Aug. 2018, Oncotarget, 9(62) (62), 31971 - 31984, English, International magazine[Refereed]Scientific journal
- PURPOSE: We developed a new analytical method to quantify the dopamine transporter (DAT) radiation dose in the striatum on [123I] FP-CIT single-photon emission computed tomography (SPECT). This method is based on the dopamine transporter standardized uptake value (DaTSUV). The purpose of this study was to compare DaTSUV with the classical specific binding ratio (SBR) in the discrimination of dopaminergic neurodegenerative diseases (dNDD) from non-dNDD. METHOD: Seventy-seven consecutive patients who underwent DaTscan were included. Patients were divided into a dNDD group (n = 44; 24 men, 20 women; median age 73 years) and a non-dNDD group (n = 33; 14 men, 19 women; median age 75 years) based on their clinical diagnoses. The relationship between each method was evaluated by Pearson's correlation coefficient. Differences in SBR and DaTSUV in each group were evaluated by t test. Pairwise comparison of receiver operating characteristic (ROC) curve analysis was performed to compare the discriminating abilities of each method according to the standard error of the area under the curve (AUC). A value of p < 0.05 was considered statistically significant. RESULT: There was a significant strong correlation between DaTSUV and SBR (r = 0.910 [95% CI = 0.862-0.942], p < 0.001). The dNDD group showed significantly lower SBR (3.48 [1.25-7.91] vs 6.58 [3.81-11.1], p < 0.001) and DaTSUV (4.91 [1.59-13.6] vs 8.61 [2.29-15.6], p < 0.001) than the non-dNDD group. The discriminating ability of SBR (AUC = 0.918) was significantly higher than that of DaTSUV (AUC = 0.838, p = 0.0176). CONCLUSION: DaTSUV has a good correlation with SBR, but it could not exceed SBR for discriminating dNDD from non-dNDD.Aug. 2018, Neurological sciences : official journal of the Italian Neurological Society and of the Italian Society of Clinical Neurophysiology, 39(8) (8), 1401 - 1407, English, International magazine[Refereed]Scientific journal
- OBJECTIVES: To report MR imaging features of mammary analogue secretory carcinoma (MASC) and acinic cell carcinoma (AciCC) of the salivary gland based on the latest version of the World Health Organization (WHO) 2017 classification of head and neck tumours. METHODS: MR images in 4 patients with MASC and 4 with AciCC were reviewed for margin characteristics, the presence of pathological cervical nodes, the presence of a cystic component and interface between cystic and solid component, signal intensity of the cystic components on T1 weighted images, and signal intensity of the solid component on T1 and T2 weighted images. RESULTS: All the MASCs and AciCCs had well-defined boundaries, and 1 AciCC had pathological nodes. All 4 MASCs presented as predominantly cystic tumours with papillary projection of the solid component. All 4 AciCCs presented as solid tumours. The signal intensity of the cystic components on T1 weighted images was entirely hyperintense in 2, and partly hyperintense demonstrating fluid-fluid level in 2. In all the MASCs, the signal intensity of the solid components on T1 weighted images was intermediate. In the AciCCs, the signal intensity of the solid components on T1 weighted images was high in 2 tumours and intermediate in 2. The signal intensity of the solid components on T2 weighted images varied from low to high in both MSACs and AciCCs. CONCLUSIONS: All 4 MASCs had a large cystic component, including areas of high signal intensity on T1 weighted images. The solid component appeared as a papillary projection into the cystic component. All 4 AciCCs presented as solid tumours, 2 of which showed high signal intensity on T1 weighted images.Jul. 2018, Dento maxillo facial radiology, 47(5) (5), 20170218 - 20170218, English, International magazine[Refereed]Scientific journal
- PURPOSE: In subjects with amyloid deposition, striatal accumulation of 11C-Pittsburgh compound B (PiB) demonstrated by positron emission tomography (PET) is related to the stage of Alzheimer's disease (AD). In this study, we investigated the correlation between striatal and cortical non-displaceable binding potential (BPND). METHODS: Seventy-three subjects who complained of cognitive disturbance underwent dynamic PiB-PET studies and showed positive PiB accumulation were retrospectively selected. These subjects included 34 AD, 26 mild cognitive impairment, 2 frontotemporal lobar degeneration, 2 Parkinson's disease, 5 dementia with Lewy bodies, and 4 undefined diagnosis patients. Individual BPND images were produced from the dynamic data of the PiB-PET study, and voxel-based analyses were performed to estimate the correlations between striatal and other regional cortical BPND measures. RESULTS: There were highly significant correlations between striatal and prefrontal BPND, with the highest correlation being demonstrated in left Brodmann area 11. We found that almost all of the high cortical BPND values correlated with striatal BPND values, with the exception of the occipital cortex with low correlation. CONCLUSION: Our study demonstrated positive correlations in amyloid deposits between the striatum and other cortical areas with functional and anatomical links. The amyloid distribution in the brain is not random, but spreads following the functional and anatomical connections.Jul. 2018, Annals of nuclear medicine, 32(6) (6), 398 - 403, English, Domestic magazine[Refereed]Scientific journal

- BACKGROUND AND AIMS: The purpose of this prospective study was to demonstrate the ability to measure pancreatic tumor tissue blood flow (TBF) with a noninvasive method using xenon inhalation computed tomography (xenon-CT) and to correlate TBF with histological features, particularly microvascular density (MVD). METHODS: TBFs of pancreatic tumors in 14 consecutive patients were measured by means of xenon-CT at diagnosis and following therapy. Serial abdominal CT scans were obtained before and after inhalation of nonradioactive xenon gas. TBF was calculated using the Fick principle. Furthermore, intratumoral microvessels were stained with anti-CD34 monoclonal antibodies before being quantified by light microscopy (×200). We evaluated MVD based on CD34 expression and correlated it with TBF. RESULTS: The quantitative TBF of pancreatic tumors measured by xenon CT ranged from 22.3 to 111.4 ml/min/100 g (mean ± SD, 59.6 ± 43.9 ml/min/100 g). High correlation (r = 0.885, P < 0.001) was observed between TBF and intratumoral MVD. CONCLUSION: Xenon-CT is feasible in patients with pancreatic tumors and is able to accurately estimate MVD noninvasively.3, Mar. 2012, Digestive diseases and sciences, 57(3) (3), 801 - 5, English, International magazine[Refereed]Scientific journal

- We report the case of a liver abscess associated with microwave coagulation therapy (MCT). A 67-year-old man underwent a pylorus-preserving pancreatoduodenectomy for bile duct cancer in August 1998. In June 1999, abdominal computed tomography (CT) showed three low-density areas in his liver. With a diagnosis of multiple metastatic liver tumors, we applied MCT to each liver tumor. The patient presented with fever after therapy. Abdominal CT showed a hepatic abscess, which was treated by percutaneous transhepatic abscess drainage under ultrasonography. A bacteriological examination of the pus material revealed the presence of Enterococcus faecalis and Candida albicans. Treatment resulted in a rapid resolution of symptoms. Our case indicated that care should be exercised in using MCT for the treatment of liver tumors in patients who have undergone reconstructive surgery of the biliary tract.2002, Surgery today, 32(5) (5), 454 - 7, English, Domestic magazine

The purpose of this study was to evaluate the effect of a hybrid-type iterative reconstruction method on Z-score mapping of hyperacute stroke in unenhanced computed tomography (CT) images. We used a hybrid-type iterative reconstruction [adaptive statistical iterative reconstruction (ASiR)] implemented in a CT system (Optima CT660 Pro advance, GE Healthcare). With 15 normal brain cases, we reconstructed CT images with a filtered back projection (FBP) and ASiR with a blending factor of 100% (ASiR100%). Two standardized normal brain data were created from normal databases of FBP images (FBP-NDB) and ASiR100% images (ASiR-NDB), and standard deviation (SD) values in basal ganglia were measured. The Z-score mapping was performed for 12 hyperacute stroke cases by using FBP-NDB and ASiR-NDB, and compared Z-score value on hyperacute stroke area and normal area between FBP-NDB and ASiR-NDB. By using ASiR-NDB, the SD value of standardized brain was decreased by 16%. The Z-score value of ASiR-NDB on hyperacute stroke area was significantly higher than FBP-NDB (p<0.05). Therefore, the use of images reconstructed with ASiR100% for Z-score mapping had potential to improve the accuracy of Z-score mapping.

(対象と方法) 対象は肝細胞癌(HCC)が既知又は疑われ,64列MDCTでダイナミックMDCTを施行した128例である.このうち36名が合計56結節の多血性HCCを罹患していた. 63名の患者に525mgヨード/kg(mgI/kg)の造影剤が用いられ(プロトコールA),62名の患者に630mgI/kgの造影剤が用いられた(プロトコールB). 造影剤の注入時間は30秒とした. 動脈相,門脈相,平衡相,各相における腹部大動脈,門脈,肝静脈,肝実質とHCCのCT値を計測した.HCCの計測値から肝実質の計測値を引いた値を腫瘍-肝実質コントラスト(TLC)と定義し,プロトコールA,Bの間で比較した. 統計的分析はMann-Whitney U testを用いた. なお,この研究は,臨床試験審査委員会の承認と患者の同意が得られている. (結果) 大動脈の動脈相,門脈相,平衡相,各相におけるCT値は,プロトコールAでそれぞれ313,153,120HU,プロトコールBでそれぞれ351,166,132HUであり,すべての相において,大動脈の造影効果はプロトコールBの方がAより有意に高かった(P<0.01). 門脈の各相におけるCT値は,プロトコールAでそれぞれ146,167,122HU,プロトコールBで163,190,136HUであり,すべての相において,門脈のCT値はプロトコールBの方がAより高かった(P=0.023,P<0.001,P<0.001).肝静脈の各相におけるCT値は,プロトコールAでそれぞれ124,112,111HU,プロトコールBで126,139,124HUであり,門脈相,平衡相ともに,肝静脈のCT値は有意にプロトコールBの方が高かった(P<0.001). 肝実質の各相におけるCT値は,プロトコールAで77,112,100HU,プロトコールBで82,121,108HUであり,肝実質の造影値は門脈相,平衡相で有意にプロトコールBの方が高かった(P<0.001). TLCの各相における値はプロトコールAで28.0,-9.8,-12.1HU,プロトコールBで37.4,-11.8,-13.6HUであり,TLCは動脈相でプロトコールBの方が有意に高かった(P=0.042). (結論)630mgI/kg量の造影剤投与の方が,525mgI/kgよりも動脈相における多血性HCCの肝臓とのコントラストをより向上させた. また,平衡相において50HU以上の十分な肝実質造影を呈した.近畿大学医学会, Sep. 2012, 近畿大学医学雑誌, 37(3) (3), 155 - 162, Japanese

- 〈原著〉64列多列化CTを用いた新しい定量的心筋灌流イメージング法[抄録] 目的:コンピューター断層撮影(CT)と逆積分解析法を用いた定量的な組織灌流定量的評価法が心筋灌流分析に適用できるかは不明である.今回,我々は64列多列化CTと逆積分法を用いて算出した定量的心筋灌流イメージング法の評価を行った. 方法:正常例10例と急性心筋梗塞(AMI)患者19例で組織血流量(TBF),組織血液量(TBV),平均通過時間(MTT)の3つの灌流指標を逆積分解析によって算出し,single photon emission computed tomography(SPECT)像を含む臨床指標との比較を行った. 結果:正常例における左心室心筋のTBFは,128.44±20.79ml/100g/minであり,従来の報告と近似していた.AMI患者では,梗塞領域のTBFとTBVは非梗塞領域より有意に低値であった(p<0.01).梗塞領域のMTTは,非梗塞領域より延長していた(p<0.01).TBVカラーマップにおける血流低下領域の面積は,血清クレアチンキナーゼピーク値,QRSスコア,SPECT欠損スコアと有意な正の相関を示した(p<0.05).TBFの心外膜側/心内膜側比は,側副血行路が発達した群で乏しい群に比較して有意に高値であった(p<0.01). 結論:AMI患者における心筋灌流異常を,当方法を用いて初めて定量的に検出できた.当方法はAMIの臨床評価に有用であることが示唆された.近畿大学医学会, Dec. 2010, 近畿大学医学雑誌, 35(3) (3), 167 - 175, Japanese
- 〈原著〉三次元CT画像を用いた冠動脈の起始異常および開口部起始位置の解剖学的調査[抄録]近年,冠動脈病変の評価において,マルチスライスCT(MDCT)による心電図同期再構成法を用いた冠動脈の血管撮影の有用性が確立されてきている.冠動脈の走行状態や起始分岐異常分類に関する研究は多いが,起始位置の幾何学的な形態調査研究は少ない.本研究はMDCTによって得られた三次元画像を用い,邦人の冠動脈起始異常の発現率およびその分岐形態の幾何学的情報についての解剖学的調査研究である.分岐異常を有した症例は1,053例中,高位起始症例が0例,左前下行枝と左回旋枝が分離して起始する症例が8例(0.755%),右冠動脈が左冠尖から分岐する症例が6例(0.570%)の合計14例(1.330%)認められた.正常分岐症例の評価における冠動脈の分岐角度は,左冠動脈に比べ右冠動脈が有意に鈍角で,左右冠動脈間の分離角度は139.9°±17.3離れて分岐しており,男女間では有意差は無かった.Valsalva洞底部から冠動脈起始部までの距離は,左冠動脈(10.84±2.80mm)に比べ右冠動脈(11.94±3.05mm)の方が有意に高い位置で分岐し,男女間では左右冠動脈とも男性の方が高い位置で分岐していた.三次元画像による冠動脈の起始位置の形態評価で,冠動脈の起始の形態は個人差が大きいことが判明し,本邦におけるデータベースを構築できた.これは今後,冠動脈形成術施行時の術前評価や解剖教育などに貢献できる.近畿大学医学会, Dec. 2010, 近畿大学医学雑誌, 35(3) (3), 177 - 184, Japanese

- The aim of the work described here was to develop a magnetic resonance (MR) technique for guiding a Focused Ultrasound Surgery (FUS) focal point to a specific target in the liver, which is mobile and deforms with respiration. In the present approach, vessels were used as landmarks for liver tissue tracking. The translational distances and amount of expansion and contraction of the tissue were analyzed by locating the center of gravity of veins by filtering the sagittal, cine MR images of the liver during free breathing. Target locations at which the FUS foci were to be located were identified using information provided by the positions of the veins at each time point. In healthy volunteer experiments (N=2), the lower limit of the spatial matrix dimension for delineating the contour of the veins was 128×128. The average displacement of the liver was 19.6±3.6 mm in the superior-inferior (SI) direction and 3.1±1.4 mm in the anterior-posterior (AP) direction. The deformation was 3.7±1.1 mm in the SI direction and 3.0±1.2 mm in the AP direction. The gaps between the actual and the estimated target points were 0.7±0.5 mm SI, 0.6±0.4 mm AP, and 1.0±0.5 mm linearly with the vessel combinations used in this work. Temperature elevations simulated by using a bio-heat transfer equation revealed that the temperature elevation loss around the center of the focus in the liver under target tracking was about 20% of that occurring with breath holding. These results suggest that the proposed technique is sufficiently accurate for targeting the FUS focus on a specific tissue location and for tracking the slice slab for thermometry to observe regional heating.Japanese Society for Thermal Medicine, 20 Dec. 2007, Thermal Medicine(Japanese Journal of Hyperthermic Oncology), 23(4) (4), 181 - 193, English

- Automated Determination of the Liver Boundary in CT Data Based on Anatomical Knowledge and Level Set MethodAutomatic determination of the liver boundary in CT images is difficult due to similar intensity of liver with respect to its surrounding tissues, poor in-plane and inter-plane resolutions, and partial volume effect. Assumptions made in previous liver segmentation algorithms cannot be used to all cases since liver shape and location varies much in abdomen. In this article, we first estimate an initial mask to find intensity of liver accurately. We then convert gray-scale CT images to colored images so that separate liver tissues in lower slices can be seen well. The borders of these estimated tissues are used as the initial border of liver and tuned by active contour method. We extract the required parameters of each dataset from itself. Results are in agreement with the proposed method.The Institute of Electronics, Information and Communication Engineers, 20 Jan. 2007, IEICE technical report, 106(510) (510), 83 - 86, English

- Tracking 3D Branching Vascular Structures from Liver CT Images Based on Branch Point Analysis Using Local Intensity DistributionsUnderstanding the structure and morphology of the hepatic vessels is important for liver surgical planning. In this paper, we present a new centerline tracking method for extraction of 3D branching vascular structures with minimum user operations and acceptable processing time. The requirement for user operations in our method is to set initial tracking position and orientation. Once they have been set, the method automatically tracks centerlines and determines branch and terminal points as well as new positions and orientations at the detected branch points for restarting the tracking. The method uses two different algorithms for detecting the vessel directions and branching points; one is based on region growing using automatically determined threshold, and the other is based on local intensity distribution analysis, which is more robust against subtle structures and used when the threshold determination is unreliable. In experiments using 14 liver CT data sets, the method could extract 80% of hepatic arteries observable in the cross-sectional images by a radiologist.The Institute of Electronics, Information and Communication Engineers, 20 Jan. 2006, IEICE technical report, 105(579) (579), 57 - 60, Japanese

- Identification of the liver segmental anatomy based on global location peripheral portal venous branches using 3D CT dataUnderstanding the structure and morphology of the hepatic vessels and approximation of liver segments is important for liver surgical planning. In this paper, we present a method to determine the anatomical labels of the portal vein subtrees for the purpose of the liver segment approximation. We especially address the problems inherent in labeling the portal vein, which are that the patient often has variant intrahepatic portal vein anatomy and multiple portal subtrees are able to have the same label. The user of our system can interactively perform the labeling by repeating the division of the portal vein structures described as a graph into two parts. In each division, the user defines the position and orientation of a dividing plane with a margin space of a certain width. In the margin space, labeling is disambiguated based on the global position information of subtrees of the graph. In experiments, we evaluated the method using twelve CT data sets, from eleven of which the radiologist could successfully obtain appropriate labeling results within acceptable time. Further, we confirmed that the margin space was useful to stabilize the labeling results.The Institute of Electronics, Information and Communication Engineers, 15 Jan. 2005, IEICE technical report., 104(580) (580), 169 - 174, Japanese

- Focused ultrasound surgery (FUS) is a completely noninvasive, focal thermal ablation method. Various clinical applications of ultrasound-guided FUS have been investigated over the last five decades. However, three inherent challenges limited the clinical efficacy of FUS until recently : imprecise localization, inability to monitor temperature elevation at the focal point, and difficulty evaluating the procedure's success during or immediately after treatment. Recent advances in magnetic resonance (MR) imaging have resolved these problems. Pretreatment MR images enable precise target definition and treatment planning. Temperature-sensitive phase-difference MR imaging can monitor the focal point and measure tissue temperature elevation in real time, ensuring delivery of a therapeutic dose. Posttreatment gadolinium-enhanced MR images provide immediate assessment of the treatment's success. In this article we review the principles, therapeutic methods, and clinical applications of MR image-guided FUS.Japanese Society for Thermal Medicine, 2005, Jpn J Hyperthermic Oncol, 21(3) (3), 129 - 137, English

- 大腸癌診療の画像診断においては,原発巣の描出,進達度診断と共に,転移巣の発見および鑑別診断が重要になってくる.原発巣の描出には一般的にはバリウム注腸造影や大腸ファイバーが行われており,その精度と有用性は疑うべくもない.しかしこれらの検査は,腫瘍の形態や壁の硬さなどの様子を内腔より観察するものであり,壁内外や他臓器への進展度(T分類),リンパ節転移(N分類),遠隔転移(M分類)を評価することはできない.日本大腸肛門病学会, 01 Sep. 2004, 日本大腸肛門病学会雑誌, 57(9) (9), 487 - 487, Japanese
近年,CTやMRIでは高速撮像法が飛躍的に進歩し,時間,空間分解能の高い画像が撮れるようになった.特に,近年臨床応用可能となったマルチスライスCTでは,従来のヘリカルCTに比して10倍以上の高速撮像が可能であり,広い範囲を薄いスライス厚で撮像できるようになった.この画像から,描出に関しては腸管内腔からの3次元画像である仮想内視鏡像を作成することができる.また,腫瘍と接する壁に垂直な画像を再構成することもできるため,腫瘍の壁浸潤も評価できる.更に,広い範囲のリンパ節,遠隔転移の評価も可能である.このように,腫瘍のみならず転移巣も詳細に評価することができる.一方,MRIはマルチスライス CT程の空間分解能はないが,そのコントラスト分解能の高さから腫瘍の壁内浸潤を評価しやすい.広い範囲の代謝の更新した部分を描出できるPETは,原発巣の描出にも有用とされているが,現在は主に局所再発の有無やリンパ節転移,遠隔転移の有無の評価に用いられている.前述のMDCTとの融合像(CT-PET像)を用いれば,更に描出能の向上が期待できる.
大腸がんの転移しやすい臓器としては,門脈血流の帰る肝臓が第一に挙げられる.肝転移は,手術や動注化学療法など比較的治療できる可能性が高い部位であり,またその有無は原発巣の手術の適応にもかかわってくるため,その評価は非常に重要である.従来は,動脈性門脈造影下CT(CTAP)がもっとも描出能が高く有用とされていたが,その侵襲性の高さや高額な検査費用が問題であった.最近は肝臓の網内系に選択的に取り込まれる超常磁性体酸化鉄粒子(Superparamagnetic iron oxide,SPIO)を用いた造影MRIがCTAPに劣らない診断能があるとされている.
MDCT,MRI,PETをうまく組み合わせることにより,腫瘍のみならず転移巣も詳細に,低侵襲に評価することができる. - 25 Jul. 2004, 日本医学放射線学会雑誌, 64(5) (5), 344, Japaneseすい腫よう血流の定量的評価:Xe‐CTとperfusion‐CTにおける比較検討

Five re aders retrospectively assessed the probability of the presence of MIBCs with Likert and VI-RADS scores. The inter-observer agreement was assessed by mea suring intraclass correlation coefficients (ICC). Receiver operating charact eristic (ROC) analysis was used to evaluate the diagnostic performance for M IBCs. Areas under the ROC curves (AUC) were estimated for ordinal score asse ssments.[Results] Out of 111 patients, 57 had MIBCs. Inter-observer agreemen t was excellent for Likert and VI-RADS scores (ICC; 0.81 vs 0.81). AUCs show ed no significant difference between the Likert and VI-RADS scores for all r eaders (P>0.05). [Conclusion] The VI-RADS score showed an excellent inter -observer agreement and high diagnostic performance for MIBCs equivalent to the Likert scale.

- New Energy and Industrial Technology Development Organization, NEDO, Tokyo Institute of Technology, Apr. 2020 - Mar. 2022, Coinvestigator説明できるAIの基盤技術開発/モジュール型モデルによる深層学習のホワイトボックス化本研究の目的は、Dual-Energy CTで撮像したダイナミック造影CTから得られるヨードマップを用いて膵癌内部の線維性間質の多寡を定量測定することにより、非侵襲的に膵癌の悪性度ならびに治療抵抗性の予測を行うことである. 前の先行研究として、膵癌線維化マーカーであるCollagen fiberならびに活性化膵星細胞と予後との関連を後方視的に評価した。手術加療が行われた通常型膵管癌162症例に対してCollagen量を評価するEVG染色、活性化膵星細胞を評価するα-SMA染色を行い評価したところ、Collagen fiberおよびα-SMA陽性細胞が高度の膵癌は生存率が延長する傾向にあった。また線維化高度な膵癌では腫瘍内のCD8陽性T細胞が多いことも判明した。この結果から、膵癌においては線維化が高度な症例で予後が良く、腫瘍内免疫状態とも関連している可能性が示唆された。続いて造影CT平衡相画像から線維化を予測可能かを評価した。線維化予測指標としてECV fractionを利用して38例において評価を行った所、ECV fractionとCollagen fiberの程度に中等度の相関が見られたが(ρ=0.602、P=0.028)、α-SMA陽性細胞との程度には相関は認められなかった(ρ=0.317、P=0.346)。造影CT平衡相における評価は検討症例数を増やすとともに、ヒストグラム解析の追加を検討している。 また膵実質の線維化の有無を造影CT平衡相画像から評価できるかどうかの検討を行った。造影CTから算出されたECV fractionと組織的な膵線維化には相関関係があり(ρ=0.439、P<0.001)、臨床的な術後膵液瘻の予測因子として病変が浸潤癌かどうか、ECV fraction低値であることが多変量解析で判明した。 なお、Dual-Energy CTを用いた膵癌線維性間質の評価を行うための研究に対しては臨床症例の集積を行っており、106例の症例集積が得られたため今後評価を行う。Competitive research funding

In the phantom experiment, R1 values and R2* value showed excellent correlation with the concentrations of Gd-EOB-DTPA and excellent correlation was achieved between R1 and R2* values. In the clinical study, changes in R2* value and MELD score or ICG-R15 suggests that R2* map is useful for the quantitative estimation of liver function with whole liver coverage. Whereas in the limitation, R2* maps are sensitive to motion and susceptibility artifact especially in the left lobe of the liver, and cannot quantify liver function when extensive iron accumulation exist within the liver.

This prospective study assessed the feasibility of quantitative evaluation of Lp retention using iodine density images from dual-energy CT for predicting local recurrence of HCC after Lp-TACE. We performed a phantom experiment which proved that CT attenuation values saturated at 3071 HU, while measured iodine density showed excellent linearity. In a clinical study, morphological parameters derived from iodine density images showed higher hazard ratios for local recurrence of HCC than visual grades.
