Spearman rank correlation coefficients (rho) and corresponding P values of vAI versus asymmetry indices from hemodynamic parameters FMT, rCBF, Tmax, 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.
