This prospective study described diffusion change in perihematomal edema during acute stage (within 7 days) after primary intracerebral hemorrhage by using functional diffusion map (fDM). fDM allows a spatial, voxel by voxel tracking of changes in ADC values over time that more precisely reflect the pathophysiological heterogeneity within the edema. Using fDM to evaluate the perihematomal edema appears promising in this study. fDM is feasible in predicting clinical outcome of ICH patient during acute stage.
