| rMTT | 1.41 (1.34, 1.55) | 1.03 (0.91, 1.17) | −6.974 | < 0.01 |
| rTTP | 1.38 ± 0.12 | 1.05 ± 0.12 | 16.321 | < 0.01 |
| rTmax | 3.7 ± 1.1 | 1.4 ± 0.9 | 14.694 | < 0.01 |
AIS, acute ischemic stroke; rCBF, relative cerebral blood flow; rCBV, relative cerebral blood volume; rMTT, relative mean transit time; rTTP, relative time to peak; rTmax, relative time to maximum of the residual function.
