Fig 4.

The spatial distribution of the differences between FAIR and PICORE ASL. Higher signal for FAIR (red-yellow) was present notably in both convexities, which largely but not completely respected the anterior circulation, for example posterior division of the cingulate gyrus (posterior cerebral artery, posterior circulation). In contrast, PICORE had higher signal in the bilateral thalami and occipital and infratentorial regions, largely but not completely respecting the posterior circulation and additionally in the bilateral head of caudate nucleus (lenticulostriate arteries, anterior circulation) and posterior insula (middle cerebral artery, anterior circulation).
