Dynamic <scp>pseudo‐continuous arterial spin labeling</scp> angiography using a <scp>3D</scp> ‐radial multi‐spoke <scp>spoiled gradient‐recalled</scp> sequence
This study demonstrated the clinical feasibility of a novel time-resolved ASL sequence using a multi-spoke 3D-radial readout with a vessel-signal optimized flip angle sweep. Sufficient SNR, superior spatial and temporal resolution to CE-MRA, and a comparable spatial resolution to TOF MRA were achieved in a clinically reasonable acquisition time.
