  Compared with CINE phase contrast MRI (CINE-PC), echo-planar imaging phase
contrast (EPI-PC) can achieve realtime quantification of blood flow, with lower
SNR. In this study, the pulsating real model of the simulated cerebral
vasculature was used to verify the accuracy of EPI-PC. The imaging time of
EPI-PC was 62ms/image at 100*60 spatial resolution. The reconstructed EPI-PC
flow curve was extracted by homemade post-processing software. After comparison
with the CINE-PC flow curve, it was concluded that EPI-PC can provide an
average flow with less than 3% error, and its flow curve will be similar to the
CINE-PC flow curve in shape.
