Note: P values were calculated by comparison of variables (using Mann-Whitney U-test) between low-perfusion (group 1) and high-perfusion (group 2) subgroups, based on CBF asymmetries comparing sides ipsi- vs. contralateral to the angioma.

Abbreviations: BA-AI: brain atrophy asymmetry index; CBF: cerebral blood flow; CBV: cerebral blood volume; MTT: mean transit time; Ipsi: ipsilateral, Cont: contralateral (to angioma); AI = asymmetry index
