Regions yielding successful group classification. Figures showing the significant regions of interest which predicted group classification using all MR modalities to differentiate neurodegenerative disorders from healthy aging (top row); differentiate neurodegenerative disorders from healthy aging (middle row) using ASL (red/yellow; left), DTI (FA = green; MD = yellow; AD = purple; RD = pink; middle) and volumetrics (blue; right); differentiate the three group neurodegenerative subtypes from healthy aging (bottom row) using ASL (left), DTI (middle) and volumetrics (right). ASL, arterial spin labeling; DTI, diffusion tensor imaging; FA, fractional anisotropy; MD, mean diffusivity; AD, axial diffusivity; RD, radial diffusivity.
