Abstract
A dynamic MRA study of a subject is performed using a 3D fast gradient-recalled echo pulse sequence after the subject is injected with a contrast agent. The sampling of k-space is synchronized with the peak of the contrast enhancement profile by sampling in an inward spiral pattern during the rise in enhancement and by sampling in an outward spiral pattern after peak enhancement occurs.
