In this study, a fast non-contrast enhanced time-resolved 4-D dynamic MRA (dMRA) using 3D stack of stars golden angle acquisition was developed for 7T. Compared to the standard Cartesian-based non-contrast dMRA, the golden angle radial-based dMRA provides the advantages of shorter scan time (less than half of the scan time) and improved delineation of distal arteries. Preliminary data on an arterio-venous malformation shows the potential clinical utility of this radial-based dMRA technique at 7T.
