Velocity selective arterial spin labeling (VSASL) is a spatially non-selective method that labels spins based on their flow velocity, thereby labeling closer to the target tissue, reducing the influence of arterial transit time (ATT) and requiring no planning. In the abdomen, motion and complex vascular anatomy might, however, require dedicated VS-labeling parameters. We assessed the feasibility of VSASL for renal perfusion measurement by investigating its dependency on essential labeling parameters, and by comparing it with pseudo-continuous ASL (pCASL) as a spatially-selective reference ASL-technique. Our results show, that with carefully chosen sequence parameters, VSASL is feasible for renal perfusion measurement.
