First, we optimized the preparation time of peripheral gaining on Quiescent Interval Single Shot (QISS) MR Angiography for extremities. Second, we compared QISS MR Angiography using peripheral gating with Delta Flow MRA with QISS using peripheral pulse gating provides good image quality in the pelvis and extremities, which is equal to that with Delta Flow. When gadolinium cannot be used, with peripheral pulse gating, unenhanced MRA with QISS and Delta Flow can be used.
