Table 2: 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.
