Summary of mean diffusivity values (in mm2/s) measured in vCJD patients, sCJD patients, and controls for each ROI at b = 3000 s/mm2 with P values from post hoc comparisons
| Group | SP | C | P | DM | Pu | FWM |
|---|---|---|---|---|---|---|
| (A) vCJD | 524.5 (87.7) | 554.8 (69.4) | 530.3 (49.7) | 584.7 (48.1) | 603.2 (59.0) | 556.6 (23.7) |
| (B) sCJD | 493.9 (87.9) | 478.4 (27.5) | 477.1 (77.8) | 485.8 (87.4) | — | 539.5 (39.9) |
| (C) Control | 484.1 (19.9) | 628.3 (15.4) | 594.8 (8.8) | 627.3 (13.1) | 625.4 (10.6) | 528.3 (41.4) |
| A versus C | P = .652 | P = .063 | P = .156 | P = .460 | P = .432 | P = .444 |
| A versus B | P = .800 | P = .068 | P = .302 | P = .050 | — | P = .759 |
| B versus C | P = .977 | P = .001 | P = .014 | P = .007 | — | P = .885 |
Note:—b = 3000 s/mm2 (group averages for 4 vCJD and 5 sCJD patients). All data are expressed as mean values with SD in parentheses. Significant P values are in bold.
