Perforating artery flow at 3 and 7 tesla MRI using all detected perforating arteries.
| 3 tesla (n = 28) | 7 tesla (n = 29) | |
| Ndensity (#/cm2) | 0.21 ± 0.11 | 0.95 ± 0.21 |
| Vmean (cm/s) | 6.04 ± 1.27 | 3.89 ± 0.56 |
| PI | 0.49 ± 0.19 | 0.28 ± 0.08 |
Results are presented as mean ± standard deviation. Ndensity, number of detected perforating arteries/cm2; Vmean, mean blood-flow velocity; PI, pulsatility index.
