Renal perfusion imaging using contrast media injection
is potentially nephrotoxic. Arterial spin labeling
(ASL), employing endogenous contrast, was shown using
pulsed and pseudo-continuous labeling strategies. We
investigated the feasibility of velocity selective ASL
(VS-ASL), which eliminates label planning and possibly
improves perfusion SNR by labeling closer to the target
tissue. We show that renal VS-ASL is feasible, clearly
showing the expected corticomedullary perfusion
distribution in healthy volunteers. However, VS-ASL is
sensitive to motion, especially during labeling. It
could benefit from outlier rejection techniques or
prospective and retrospective motion correction.
