Dual Venc 5D flow MRI with Increased Velocity Dynamic Range: An in-vitro and in-vivo Validation and Feasibility Study

We illustrate a pilot study of the first implementation of dual-venc 5D flow MRI. We found excellent voxel-wise agreement with single-venc 5D flow in a pulsatile phantom. In two healthy controls, we find good agreement, but identify unexpected aliasing in the dual venc 5D flow which requires further investigation.
