Note. The values are mean (standard deviation) values of voxels inside the white matter, not a mean (standard deviation) of a group sample. Abbreviations: MDI, mean dispersion index, MFA of MEAN, mean fractional anisotropy of the mean averaging method, MFA of MED, mean fractional anisotropy of the median averaging method. All means are evaluated within white matters. LIN + TC, linear normalization using six tensor components. Except for LIN + TC, nonlinear normalization was used for all evaluations.
