Introduction: The Liver Imaging Reporting and Data System (LI-RADS) categorization has been proposed as a potential prognostic indicator for primary liver neoplasms in patients with liver cirrhosis or chronic hepatitis B. This multicenter study aimed to determine whether LI-RADS categorization can offer additional post-surgical prognostic value for intrahepatic cholangiocarcinoma (ICCA) when used in conjunction with the American Joint Committee on Cancer (AJCC) guidelines.
Methods: Patients with high risk for hepatocellular carcinoma, surgically confirmed ICCAs, and available preoperative MRI were enrolled.
Objectives: This study aimed to develop nomograms for predicting post-hepatectomy liver failure (PHLF) in patients with hepatocellular carcinoma (HCC), using deep learning analysis of Gadoxetic acid-enhanced hepatobiliary (HBP) MRI.
Methods: This retrospective study analyzed patients who underwent gadoxetic acid-enhanced MRI and hepatectomy for HCC between 2016 and 2020 at two referral centers. Using a deep learning algorithm, volumes and signal intensities of whole non-tumor liver, expected remnant liver, and spleen were measured on HBP images.
Objectives: To assess the prognostic significance of extra-pancreatic organ invasion in patients with resectable pancreatic ductal adenocarcinoma (PDAC) in the pancreas tail.
Materials & Methods: This retrospective study included patients with resectable PDAC in the pancreas tail who received upfront surgery between 2014 and 2020 at a tertiary institution. Preoperative pancreas protocol computed tomography (CT) scans evaluated tumor size, peripancreatic tumor infiltration, suspicious metastatic lymph nodes, and extra-pancreatic organ invasion.
Objective: To develop and validate a preoperative risk score incorporating carbohydrate antigen (CA) 19-9, CT, and fluorine-18-fluorodeoxyglucose (F-FDG) PET/CT variables to predict recurrence-free survival (RFS) after upfront surgery in patients with resectable pancreatic ductal adenocarcinoma (PDAC).
Materials And Methods: Patients with resectable PDAC who underwent upfront surgery between 2014 and 2017 (development set) or between 2018 and 2019 (test set) were retrospectively evaluated. In the development set, a risk-scoring system was developed using the multivariable Cox proportional hazards model, including variables associated with RFS.
Article Synopsis
- - The study aimed to evaluate the effectiveness of abdominal staging CT scans in finding liver metastasis in breast cancer patients initially diagnosed, analyzing a large cohort of 2056 patients over a two-year period.
- - The diagnostic yield (DY) was found to be low overall at 1.1%, but it significantly increased in patients with stage III cancer (3.9%) and in those with HER2-enriched cancers, suggesting certain groups may benefit more from this imaging technique.
- - Although the findings indicate that routine abdominal staging CT scans may not be necessary for all breast cancer patients, they are recommended for those with more advanced disease or specific cancer subtypes.
Introduction: Lymph node metastasis of nonfunctioning pancreatic neuroendocrine neoplasms (pNENs) potentially leads to poor survival. Given the contradictory results in the literature regarding factors associated with lymph node metastasis of nonfunctioning pNENs, we conducted a systematic review and meta-analysis to determine the preoperative predictors of lymph node metastasis.
Methods: Original studies reporting factors associated with lymph node metastasis in patients with nonfunctioning pNENs were identified in PubMed, EMBASE, and Cochrane Library databases, and data from eligible studies were analyzed using random-effects meta-analysis to obtain pooled estimates of odds ratios (ORs) and their 95% confidence intervals (CIs).
Objective: Despite the revision of threshold growth (TG) in the Liver Imaging Reporting and Data System (LI-RADS) version 2018, the appropriate time period between the two examinations for TG has not been determined. We compared the accuracy of LI-RADS with TG based on tumor growth rate for the diagnosis of hepatocellular carcinoma (HCC) with that of LI-RADS v2018 based on the original TG.
Methods: Patients who underwent preoperative MRI for focal solid lesions (≤ 3.
Objective: Chronic enteropathy associated with gene (CEAS) is a recently recognized disease. We aimed to evaluate the enterographic findings of CEAS.
Materials And Methods: Altogether, 14 patients with CEAS were confirmed based on known mutations.
Objective: To develop and validate a model using radiomics features from apparent diffusion coefficient (ADC) map to diagnose local tumor recurrence in head and neck squamous cell carcinoma (HNSCC).
Materials And Methods: This retrospective study included 285 patients (mean age ± standard deviation, 62 ± 12 years; 220 male, 77.2%), including 215 for training (n = 161) and internal validation (n = 54) and 70 others for external validation, with newly developed contrast-enhancing lesions at the primary cancer site on the surveillance MRI following definitive treatment of HNSCC between January 2014 and October 2019.
Triage is essential for the early diagnosis and reporting of neurologic emergencies. Herein, we report the development of an anomaly detection algorithm (ADA) with a deep generative model trained on brain computed tomography (CT) images of healthy individuals that reprioritizes radiology worklists and provides lesion attention maps for brain CT images with critical findings. In the internal and external validation datasets, the ADA achieved area under the curve values (95% confidence interval) of 0.

Method: Patients with surgically resected lung cancer without pathological node metastasis between June 2010 and December 2017 were retrospectively included. Clinical T stages were determined based on the maximal tumor size on axial, multiplanar (axial, coronal, and sagittal) images and 3-dimensional tumor mask.
Background: Transcatheter arterial embolization (TAE) is not common for hemorrhagic complications after gynecologic hysterectomy.
Purpose: To evaluate the effectiveness and safety of TAE for hemorrhage after hysterectomy for gynecologic diseases.
Material And Methods: This is a retrospective, multicenter study, which investigated 11 patients (median age = 45 years) who underwent TAE for hemorrhage after gynecologic hysterectomy between 2004 and 2020.
Objectives: Transcatheter arterial embolisation (TAE) is widely used to treat gastrointestinal bleeding. This paper reports the safety and efficacy of TAE for bleeding following endoscopic resection, including endoscopic mucosal resection and endoscopic submucosal dissection.
Methods: Fifteen consecutive patients (13 males, two females; mean age 62.
Purpose: Patients undergoing long-term hemodialysis may suffer upper extremity central venous access failure and require an alternative route. This study aimed to evaluate the safety and efficacy of transrenal hemodialysis catheter insertion/replacement in patients with upper extremity central venous access failure.
Materials And Methods: A multicenter retrospective cohort study was made of transrenal hemodialysis catheter insertion/replacement performed between 2014 and 2020.
