Axial CBF pulsed arterial spin-labeling maps (A and B) show multiple regions of diminished perfusion involving anterior cerebral artery/MCA watershed territories (black arrows), with T2* DSC perfusion time-to-peak maps (C) demonstrating delayed time-to-peak in these same regions (white arrows). These areas of perfusion abnormality correspond, in part, to regions of restriction diffusion/ischemic infarct on DWI (D). T.R. Miller et al.
