Acquiring high spatial resolution cine phase contrast MRI to quantify the blood flow (arteries or veins) and the cerebrospinal fluid flow (aqueduct or cervical) is challenging. The need for large number of voxels in such small section area is required to accurately quantify the flows measurements. Reduced FOV with fold-over suppression instead of spatial pre-saturation slab is an alternative to such application. The purpose of this study is to investigate the effect of oversampling option in the VNR and both the blood and CSF flow velocities measurements ex-vivo and in-vivo.
