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.
