Flow Saturation Preparation (Flow-Sat-Prep) technique, which saturates flow signals in preparation pulse with velocity encoding and crusher gradients, is a non-contrast (NC) MRA technique for selective visualization of the artery and vein. In 20 patients, NC MRA demonstrated superficial femoral arteries and/or graft vessels without overlaps of the venous or background signals. NC MRA provided identical information to that of contrast enhanced (C) MRA regarding the patency of the femoral arteries and grafts. Without side effects related contrast agents, NC MRA might replace C MRA for the evaluation of the femoral arteries.
