Reproducibility and Inter-Observer Variability of Systolic Blood Flow Velocity and 3D Wall Shear Stress Derived From 4D flow MRI in the Healthy Aorta

摘要

PurposeTo investigate the reproducibility and inter-observer variability of 3D aortic velocity vector fields and wall shear stress (WSS) averaged over five systolic timeframes derived from non-contrast 4D-flow-MRI.
