Schematic illustration of the three neurite orientation dispersion and density imaging (NODDI) metrics. Example maps of these metrics alongside those of the standard diffusion tensor imaging (DTI) metrics are provided for comparison. FA, fractional anisotropy; FW, free water; FWF, free water fraction; MD, mean diffusivity; NDI, neurite density index; ODI, orientation dispersion index.
