Colonic Malakoplakia With an Adenomatous Appearance on Magnification Endoscopy: A Case Report

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Malakoplakia is a rare chronic granulomatous disease associated with impaired macrophage phagocytosis of bacteria. Because colonic malakoplakia presents with varied endoscopic appearances, its characteristic features have not been clearly defined, and differentiation from colorectal neoplasms during endoscopy may be difficult. We report a case

Immunoglobulin G4‐Related Disease‐Like Gastric Lesion Presenting as Submucosal Tumor‐Like Lesions

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Immunoglobulin G4 (IgG4)‐related disease (RD) is a systemic fibroinflammatory condition characterized by infiltration of IgG4‐positive plasma cells (PCs). Gastrointestinal involvement may present as submucosal tumor–like lesions and poses diagnostic challenges.

Evaluation of Visibility With an Eye‐tracking System: Effectiveness of Narrow‐Band Imaging for Detecting Colorectal Adenoma and Serrated Lesions

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Image‐enhanced endoscopy may reduce colorectal cancer mortality by improving lesion detection. Narrow‐band imaging and texture and color enhancement imaging are widely used, but their diagnostic efficacy compared with white light imaging remains unclear.

A Genome‐Wide Association Study of Colorectal Cancer Mortality Outcomes Among Individuals of African and Admixture Ancestry

Molecular Carcinogenesis, Volume 65, Issue 4, Page 422-433, April 2026.
ABSTRACT African Americans have the highest colorectal cancer (CRC) mortality rates in the United States. We performed the first genome‐wide association study (GWAS) of overall and CRC‐specific mortality among African Americans with incident CRC to identify genetic contributors to CRC outcomes.

ASL 4D MRA Intracranial Vessel Segmentation With Deep Learning U‐Nets

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2384-2396, April 2026.
ABSTRACT Purpose To propose a spatio‐temporal U‐Net based network (4DST) that exploits both spatial and dynamic information while avoiding memory‐intensive 4D convolutional layers for ASL‐based non‐contrast enhanced 4‐dimensional MR angiography (4D MRA) vessel segmentation.

First In Vivo 23Na Human Imaging at 10.5 T Using a Combined Sodium‐Proton Transceiver Body Array

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2429-2441, April 2026.
ABSTRACT Purpose To demonstrate the first in vivo human 23Na MRI at 10.5 T using a novel dual‐tuned transceiver body array and to evaluate a self‐gating approach for respiratory motion compensation, focusing on renal imaging. Methods A custom‐built eight‐channel 23Na‐loop 1H‐dipole transceiver array was designed, constructed, and characterized.

Phenotype, Management, and Outcomes in Paediatric Acute Pancreatitis: A Real‐Life Cross‐Sectional Study

Acta Paediatrica, Volume 115, Issue 4, Page 951-958, April 2026.
ABSTRACT Aim Limited Canadian data on paediatric acute pancreatitis exist. A meta‐analysis of 48 studies reported equal prevalence of acute pancreatitis among various aetiologies, with rates of severe acute pancreatitis at 13.7% in North America.
