Diffusion tensor imaging data were acquired from eight patients with symptoms of large middle cerebral arterial territory stroke and eight healthy age matched controls at different time points. Region-of-interest analysis was performed on seven segments of the corpus callosum for determining the fractional anisotropy (FA), mean diffusivity, and the corresponding callosal cross-sectional areas. A significant temporal decline in FA values was observed suggesting cortico-callosal wallerian degeneration in these patients.
