Evaluation of dual-VENC and triple-VENC unwrapping algorithms. A-C, Representative 50/75/150 cm/s phase-difference images. All phase-difference images are shown for the same slice location and time point. D, The dual-VENC, triple-VENC biconditional (E) and triple-VENC triconditional (F) datasets shows successful unwrapping of most voxels, but some residual ones near the vessel wall (red arrows). Red arrows depict residual aliasing in the dual-VENC and triple-VENC unwrapped datasets
