Regions of interest in the blood supply region of two patients’ brains. (a) MRA indicated occlusion of M1 segment of the right MCA; (b) DWI showed negative; (c) ASL suggested that the CC was well established (PLD 2525 ms); (d) MRA showed that the M1 segment of the right MCA was occluded; (e) DWI showed negative; (f) ASL indicated insufficient collateral circulation (PLD 2525 ms).
