Vessel-encoded pseudo-continuous arterial spin labeling (VEPCASL) can be
used to obtain vessel-selective time-resolved angiograms. Here we compare accelerated
Cartesian and radial readouts to demonstrate the feasibility of speeding up their
acquisition, enabling better prospects for use of the method in a clinical setting.
It was possible to acquire 2D vessel-selective angiograms in less than one
minute. Accelerated (undersampled) radial acquisition consistently led to
angiograms with higher signal-to-noise ratio and better quality peripheral
artery imaging versus accelerated Cartesian imaging.
