Improved prognostication during the acute phase of intracerebral hemorrhage (ICH) could influence goals of care. We investigated the utility of diffusion tensor imaging (DTI)-derived data obtained during the acute phase of ICH in predicting outcome, compared with the ICH score.


We measured fractional anisotropy (FA) values in 5 slices below the level of the lesion on the affected and unaffected corticospinal tracts (CST) and in the cerebral peduncles (CPs) in 32 patients with supratentorial ICH who had DTI MRI within 4 days after ictus. We calculated the FA ratio (rFA = FAaffected side/FAunaffected side), and examined the value of the ICH score and rFA in predicting functional outcome assessed by modified Ranking Scale (mRS) at follow-up, using ROC analyses.


The rFA values at the CPs level, but not the 5 slices below the lesion, were significantly lower in the group with poor functional outcome (defined as mRS > 2) than in those with good functional outcome (0.96 ± 0.14 vs. 0.99 ± 0.08, p = 0.025). The ICH score had greater areas under ROC curve in predicting functional outcome compared to the mean rFA (AUC 0.74 vs. 0.44; p = 0.01 for mRS > 2; and 0.84 vs. 0.40; p < 0.001 for mRS > 3).


The prognostic value of the ICH score surpassed that of DTI-derived data during the acute phase of ICH in this cohort of patients. Prospective and larger studies are needed to validate our findings and to assess the prognostic role of various DTI-derived measures at different times following ICH.
