Intra‐Abdominal Hemorrhage Following Endoscopic Retrograde Cholangiopancreatography in a Patient with a Cascade Stomach: A Case Report

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Intra‐abdominal hemorrhage is an extremely rare complication of endoscopic retrograde cholangiopancreatography (ERCP). We report a case of intra‐abdominal bleeding that occurred after ERCP for choledocholithiasis with cholangitis in a patient with a cascade stomach.

A Voxel‐Wise T2 Distribution Framework for Lesion Severity Stratification and Treatment‐Response Assessment in Stroke: Insights Into Suberoylanilide Hydroxamic Acid‐Induced Neuroprotection

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2870-2884, December 2026.
ABSTRACT Purpose To evaluate lesion severity distribution in ischaemic brain lesions in spontaneously hypertensive rats (SHR) subjected to 90‐min transient middle cerebral artery occlusion (tMCAO), and to determine whether epigenetically based neuroprotection modifies lesion severity profiles using a voxel‐wise T2 distribution framework.

ArteryX: A Reliable End‐To‐End Toolbox for Standardized Intracranial Artery Feature Extraction From 3D TOF‐MRA

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2914-2924, December 2026.
ABSTRACT Cerebrovascular research heavily relies on quantitative analysis of intracranial arteries from time‐of‐flight magnetic resonance angiography (TOF‐MRA), yet existing processing pipelines remain limited by inconsistent artery labeling and a high manual correction burden.

Whole‐Brain 4D MRA With Improved Vessel Delineation Using Undersampled Multiple Overlapping Thin‐Slab Radial Acquisition

NMR in Biomedicine, Volume 39, Issue 12, December 2026.
A noncontrast‐enhanced 4D MRA technique by integrating pulsed ASL with undersampled multiple overlapping thin‐slab stack‐of‐stars golden‐angle radial acquisition is developed for the evaluation of whole‐brain arterial flow dynamics with improved vessel delineation. The proposed method substantially reduced RF saturation effects and preserved signals in

Technical development and implementation of 3D‐QALAS on a 1.5T MR‐Linac for the brain: A prospective R‐IDEAL stage 0/1 technology development report

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Quantitative relaxometry of the brain on the integrated MRI / linear accelerator (MR‐Linac) at high isotropic reconstructed resolution is currently limited due to prohibitively long scan times and limited field‐of‐views. Purpose The purpose of this study was to assess the technical feasibility of the 3D‐QALAS technique on the 1.5T ...

Severe ADEM‐Like Neuroinflammatory Disease and Cerebrovascular Fragility With Recurrent Pseudoaneurysms and Moyamoya in a Familial Germline CBL Mutation: Expanding the Clinical Phenotype

American Journal of Medical Genetics Part A, Volume 200, Issue 11, Page 2568-2574, November 2026.
ABSTRACT Heterozygous germline variants in CBL disrupt its function as a negative regulator of the Ras/MAPK pathway, classically predisposing to Juvenile myelomonocytic leukemia (JMML) and moyamoya. We describe two affected siblings carrying a paternally inherited CBL variant (c.1210 T> C, p.

Development and Validation of an Early Postoperative Risk Stratification Model for Hydrocephalus Following Aneurysmal Subarachnoid Hemorrhage

Brain and Behavior, Volume 16, Issue 11, November 2026.
This study developed and validated a machine learning‐based prediction model for postoperative hydrocephalus following aneurysmal subarachnoid hemorrhage (aSAH). Using retrospective data from 331 patients, we identified four key predictors: admission GCS score, admission Hunt‐Hess grade, intraoperative external ventricular drainage (EVD), and ...

Adipsic Hypernatremia Complicated by Hyperosmolar Hyperglycemic State and Extensive Venous Thromboembolism After Traumatic Brain Injury: A Case Report

Clinical Case Reports, Volume 14, Issue 11, November 2026.
ABSTRACTAdipsic hypernatremia is a rare disorder characterized by impaired thirst perception despite severe hyperosmolality, most commonly resulting from hypothalamic dysfunction. Hyperosmolar hyperglycemic state (HHS) may further aggravate dehydration and electrolyte imbalance, increasing the risk of neurologic injury, acute kidney injury (AKI), and ...
