Automatic detection and multi-component segmentation of brain metastases in longitudinal MRI.
Sci Rep
December 2024
Institute of Informatics, HES-SO Valais-Wallis University of Applied Sciences and Arts Western Switzerland, Sierre, Switzerland.
Manual segmentation of lesions, required for radiotherapy planning and follow-up, is time-consuming and error-prone. Automatic detection and segmentation can assist radiologists in these tasks. This work explores the automated detection and segmentation of brain metastases (BMs) in longitudinal MRIs.

Background: Diabetic striatopathy (DS) is a rare disorder characterized by clinical manifestations of hemichorea, non-ketotic hyperglycemia, and high signal on T1-weighted MRI or high density on CT scan in basal ganglia, typically associated with poor glycemic control.
Objective: This study aimed to analyze clinical characteristics of patients with diabetic striatopathy to raise awareness amongst physicians, especially endocrinologists, about this rare neurological manifestation in patients with diabetes.
Methods: We retrospectively analyzed the data on clinical presentations, laboratory workups, and cranial CT and MRI of six patients with DS who were admitted to our hospital from October 2013 to June 2022.
The Utility of Apparent Water Diffusion Coefficient Maps for Evaluating the Presence of Myometrial Invasion in Patients with Endometrial Cancer.

September 2024
Department of Diagnostic and Interventional Radiology, Institute of Medicine, University of Tsukuba, Tsukuba, Ibaraki, Japan.
Purpose: To assess the utility of apparent diffusion coefficient maps (ADC) for diagnosing myometrial invasion (MI) in endometrial cancer (EC).
Methods: This retrospective study included 164 patients (mean age, 56 years; range, 25-89 years) who underwent preoperative MRI for EC with <1/2 MI or no MI between April 2016 and July 2023. Five sequences were evaluated: T2-weighted imaging (T2WI), diffusion-weighted imaging (DWI), ADC, dynamic contrast-enhanced T1-weighted imaging (DCE-T1WI), and contrast-enhanced T1WI (CE-T1WI).
New Subependymal Enhancement After Radiation Therapy in High-Grade Glioma: Utilizing Morphological Features and DSC Perfusion MRI in Differentiate Progression and Post-Radiation Changes.

Department of Radiology, Seoul National University Hospital, Seoul, Republic of Korea.
Article Synopsis
- The study focuses on understanding subependymal enhancement (SE) in high-grade glioma patients post-radiotherapy, aiming to differentiate between radiation-induced changes and actual tumor progression through MRI analysis.
- Researchers analyzed data from 94 patients, utilizing advanced imaging techniques and statistical methods like logistic and Cox regression to evaluate the characteristics and outcomes of SE.
- Findings indicated that specific SE features, such as IDH mutations and certain morphological traits, could predict regression versus progression of the tumors, with 38.3% of patients experiencing SE that often regressed within a few months after initial appearance.
