Results of the SPM voxel-by-voxel group statistic for the MRI-groups Comparison between a) the seven patients with unspecific lesions in conventional MRI versus 19 healthy controls b) the 12 patients with no lesions in conventional MRI versus the same 19 healthy controls. The lines represent corresponding cut planes of the sections (−34 mm,-18 mm,-2 mm; Montreal Neurological Institute space). The color coded t-values represent significant (p < 0.01) FA reductions in the patients compared to the controls (minimum cluster size: 100 voxel).
