Microstructural modelling results. Maps of metrics estimated using various microstructural models of a representative participant. For diffusion tensor imaging (DTI) (column i), maps of axial diffusivity (AD), radial diffusivity (RD), mean diffusivity (MD) and fractional anisotropy (FA) are displayed. For diffusion kurtosis imaging (DKI), maps of axial kurtosis (AK), radial kurtosis (RK), mean kurtosis (MK), and FA from the tensor component are displayed. For white matter tract integrity (WMTI) imaging (column iii), maps of axonal water fraction (AWF), intra-axonal diffusivity (Da), axial extra-axonal diffusivity (De, para), and radial extra-axonal diffusivity (De, perp) are displayed. For neurite orientation dispersion and density imaging (NODDI) (column iv), maps of intra-neurite volume fraction (Fin), extra-neurite volume fraction (Fen), cerebrospinal fluid volume fraction (Fcsf), and orientation dispersion index (ODI) are displayed. For microscopic diffusion tensor imaging (MicroDTI) (column v), maps of microscopic longitudinal diffusivity (mLD), microscopic transverse diffusivity (mTD), microscopic mean diffusivity (mMD), and microscopic FA (mFA) are displayed. For multi-compartment microscopic diffusion (MCMicro) imaging (column vi), maps of intra-neurite volume fraction (Fin), intrinsic diffusivity (Di), microscopic extra-neurite transverse diffusivity (mTDen), microscopic extra-neurite mean diffusivity (mMDen) are displayed. The maps are windowed individually for improved visualization, between 0 and a higher intensity listed at the bottom left of each sub-figure.
