Conventional vessel-encoded arterial spin labeling (VEASL) is a territorial perfusion imaging technique to identify the perfusion territories of cerebral arteries simultaneously with prior knowledge of their positions. Recently, random vessel encoded arterial spin labeling (R-VEASL) was proposed to automate the scan prescription process. Our study compared the output of R-VEASL with the perfusion maps acquired with conventional VEASL. Quantitative comparison of perfusion territories between R-VEASL and conventional VEASL has shown that perfusion territories of both methods agree reasonably well. However, it seems that R-VEASL performs better than conventional VEASL when detecting perfusion region with mixed perfusion.
