The aim of this study was to compare the differences of perfusion territories determined by vessel-encoded and super-selective pseudo-continuous arterial spin labeling MRI. Cases are presented to illustrate the capability of either technique to determine correct perfusion territories in vascular variations and mixed perfusion areas. The results of this study show that perfusion territories of vessel-encoded and super-selective p-CASL RPI agree reasonably well. Vessel encoded ASL however fails to detect mixed perfusion areas, which leads to erroneous boundaries in these areas.
