Fully Automated Valve Segmentation for Blood Flow Assessment From 4D Flow MRI Including Automated Cardiac Valve Tracking and Transvalvular Velocity Mapping

Background Automated 4D flow MRI valvular flow quantification without time‐consuming manual segmentation might improve workflow. Purpose Compare automated valve segmentation (AS) to manual (MS), and manually corrected automated segmentation (AMS), in corrected atrioventricular septum defect (c‐AVSD)...
