Note:—CBV indicates normalized cerebral blood volume; CBF, normalized cerebral blood flow; MTT, normalized mean transit time; PC, percent change; BG, basal ganglia; ACA, anterior cerebral artery; MCA, middle cerebral artery; EBZ, anterior external border zone; BMV, basal Moyamoya vessel.
* Values are statistically significant (P < .05) by using analysis of variance and the multiple comparison test.
