| MSA-P (n = 17) | PD (n = 37) | PSP (n = 11) | HC (n = 16) | |
|---|---|---|---|---|
| T1H (mm) | 44.4 ± 6.1* | 21.6 ± 9.5 | 21.8 ± 10.1 | 26.4 ± 5.3 |
| T2H (mm) | 35.8 ± 8.6* | 21.0 ± 8.4 | 18.7 ± 7.7 | 19.3 ± 7.5 |
| T2 L (mm) | 32.7 ± 11.8† | 26.1 ± 6.8 | 29.2 ± 7.7 | 24.9 ± 6.0 |
| Atrophy (mm) | 38.4 ± 7.7* | 21.4 ± 8.3‡ | 27.5 ± 5.1 | 16.6 ± 7.7 |
Note:—T1H indicates T1 hyperintensity; T2H, T2 hyperintensity; T2 L, T2 hypointensity.
* Significantly different from PD, PSP, and HC (P < .001).
