Arterial spin labeling with variable echo time (VTE-ASL) is a perfusion imaging technique capable of noninvasive estimating of GFR. But the application of VTE-ASL in renal disease is still lagging behind. The goal of this study was to investigate the feasibility of GFR and RBF using VTE-ASL in evaluation of unilateral renal embolism in rabbits. Compared with normal kidney, embolism area has large decrease in GFR and RBF, and was confirmed by histological findings.
