We computed the radial diffusivity map on the corpus callosum of 35 healthy subjects ranging 20-80 years. A mid-sagittal template of corpus callosum was obtained by co-registeri all mid-sagittal slices in a semi automated non linear fashion. Statistical analysis was performed on the data to asses for correlation between radial diffusivity values and the normal aging process in a voxel based approach.
