Free‐Running Three‐Dimensional Cardiac Extracellular Volume Mapping in a Single Scan With Mid‐Scan Contrast Injection

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3360-3368, June 2026.
ABSTRACT Purpose To develop a new method for free‐running three‐dimensional (3D) extracellular volume mapping of the heart in a single scan with mid‐scan contrast injection. Methods 3D cardiac MR imaging was performed with a single scan that acquired k‐space data continuously using an inversion recovery (IR) sequence with a spoiled gradient‐echo ...

Colliding Wars: A Systematic Review on HIV Responses in Conflict‐Affected Settings

Public Health Challenges, Volume 5, Issue 2, June 2026.
Armed conflicts heighten HIV vulnerability among adolescent girls, refugees and displaced populations through service disruptions and health system collapse. This systematic review of 17 studies identifies promising adaptive strategies like mobile clinics and emergency stock packs to sustain HIV care.
