Parametric maps of perfusion are shown for pCASL and PASL acquisitions. (A) Structural image and (B) sample EPI image are shown for reference. Baseline, ischemia, and hyperemia perfusion maps are shown for pCASL (C–E) and PASL (F–H). The voxelwise perfusion map was computed, smoothed, and averaged over 16 seconds of acquisition (two repeats for pCASL, eight repeats for PASL). The three feeding arteries of the leg are located centrally, where aberrant perfusion values are seen.
