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.
