We investigated mean diffusivity (MD) and fractional anisotropy (FA) value changes along with white matter and gray matter volume in patients with hepatitis C compared to healthy controls using voxel based morphometry (VBM). Extensive increased MD values were observed in bilateral frontal gray and white matter, bilateral external capsule, temporal white matter, and right occipital gray matter. FA values decreased in the corpus callosum, right frontal and occipital white matter. Widespread gray matter volume reduction was seen in the frontal, parietal and temporal regions. White matter volume decreases were observed in the right frontal, corpus callosum and mid brain.
