This study aims to determine the effects of residual contrast agent on radially encoded flow sensitive MR scan quality for cardiac and renal MRI. Examination of vessel signal and diagnostic quality of the vasculature suggests significant improvement in vessel visualization following contrast administration in most vessels. This improvement in vessel conspicuity was not seen in the renal arteries, where segmental vessel visualization was reduced, which we hypothesize is due to decreased contrast from accumulation of the agent in the renal parenchyma.
