Mean FA and ADC of groups I and II versus group III (affected hemisphere only)
| FA/ADC | Groups I and II FA | Group III FA | Groups I and II ADC | Group III ADC |
|---|---|---|---|---|
| n | 18 | 7 | 18 | 7 |
| Mean | 0.51 | 0.42 | 0.75 | 0.63 |
| SD | 0.08 | 0.08 | 0.20 | 0.24 |
| P(ttest) | .03 | >.2 | ||
Note:—FA indicates fractional anisotropy; ADC, apparent diffusion coefficient. FA of patients with unfavorable outcome was significantly lower, whereas all of the subjects exhibited reduced ADC without significant differences between groups.
