Spearman rank correlation coefficients (rho) and corresponding P values of vAI versus asymmetry indices from hemodynamic parameters FMT, rCBF, T_max, MTT, and rCBV for 36 subjects.

	FMT	rCBF	Tmax	MTT	rCBV
Minimum	0.76 (P < 1 × 10−7)	−0.09 (P = .59)	0.74 (P < 1 × 10−6)	0.24 (P = .15)	0.00 (P = .98)
Maximum	0.41 (P = .013)	−0.14 (P = .42)	0.58 (P < 1 × 10−3)	0.13 (P = .45)	0.09 (P = .60)
Total	0.47 (P = .004)	−0.02 (P = .90)	0.61 (P < 1 × 10−4)	0.16 (P = .35)	0.10 (P = .55)

Note:—Correlation coefficients are computed from ROIs placed in the minimum PCA territories, maximum PCA territories, and ROIs combined from both the minimum and maximum PCA territories. P values shown are not Bonferroni corrected.
