Arterial spin labeling (ASL) can provide cerebral
perfusion images noninvasively but only obtain the
cerebral blood flow (CBF), which is sensitive to the
transit time effect, compared to the dynamic
susceptibility contrast imaging (DSC-MRI). The
combination of two ASL sequences with different post
label delay time is an efficient way to evaluate both
blood flow and transit time. In this work, the CBF
difference between 2 PLDs was compared to DSC-MRI
parameters. The CBF difference has high correlation with
TTP in DSC-MRI.
