The motion artifacts in the pelvic area using 3D-cine phase contrast (4D PC) MRI may be provide the severity results. The purpose of this study was to demonstrate the usefulness of fat suppression for the common iliac artery (CIA). The study protocol compared 4D PC MRI date without fat suppression to with principle of selective excitation technique (ProSet). We evaluated the streamline visualization, SNR of magnitude images and blood flow volume. ProSet can reduce respiration artifacts. Extending of TR by using ProSet increases SNR. Thus ProSet1-1 is the optimal fat suppression technique to improve vascular visualization.
