Figure 1.

Results of voxel-based analysis of FA and L3 maps in patient group by using TBSS. Upper panel: Red shows regions where FA correlates significantly with ALSFRS score: in highlighted areas, FA is significantly lower (p < 0.05, TFCE) when ALFSRS is lower. Lower panel: Blue shows regions where L3 correlates significantly with ALSFRS score: in highlighted areas, L3 is significantly higher (p < 0.05, TFCE) when ALSFRS is lower. For each brain section Montreal Neurological Institute (MNI) coordinates are displayed. FA: fractional anisotropy; TBSS: tract-based spatial statistics; ALSFRS: Amyotrophic Lateral Sclerosis Functional Rating Scale; L3: radial diffusivity; TFCE: threshold-free cluster enhancement.
