FIG 5. Comparison of total volumes of fibers tracked on conventional DTI versus FLAIR DTI. For all subjects, FLAIR DTI depicted significantly more tracts than conventional DTI, with individual P values of .001–.02 (Student t test; n = 5 for each individual). On average, about 17% additional fiber tracts were detected on FLAIR DTI. The group difference was also significant (P < .0005, paired Student t test; n = 7).
