Summary of mean diffusivity values (in mm2/s) measured in vCJD patients, sCJD patients, and controls for each ROI at b = 1000 s/mm2 with P values from post hoc comparisons
| Group | SP | C | P | DM | Pu | FWM |
|---|---|---|---|---|---|---|
| (A) vCJD | 741.6 (104.0) | 687.9 (70.6) | 670.9 (56.2) | 834.1 (51.3) | 837.6 (33.0) | 820.7 (44.6) |
| (B) sCJD | 753.8 (44.3) | 587.3 (84.6) | 603.3 (98.7) | 691.8 (85.7) | — | 830.9 (89.1) |
| (C) Control | 754.8 (64.9) | 722.7 (16.6) | 727.8 (24.4) | 763.7 (17.1) | 748.0 (17.4) | 773.7 (43.7) |
| A versus C | P = .949 | P = .655 | P = .382 | P = .159 | P < .001 | P = .450 |
| A versus B | P = .941 | P = .021 | P = .167 | P = .001 | — | P = .947 |
| B versus C | P = 1.000 | P = .007 | P = .018 | P = .137 | — | P = .299 |
Note:—b = 1000 s/mm2 (group averages for 8 vCJD and 9 sCJD patients). All data are expressed as mean values with SD in parentheses. Significant P values are in bold.
