Multi-level analytic strategies and metrics for diffusion images. The strategies of this study include whole-brain analysis and tract-wise analysis, and each analysis strategy uses fixel-wise and voxel-wise metrics. AD = axial diffusivity; AF = arcuate fasciculus; CX = complexity; CSD = constrained spherical deconvolution; FA = fractional anisotropy; FC = fiber cross-section; FD = fiber density; FDC = fiber density and cross-section; FWE = family-wise error; IFOF = inferior fronto-occipital fasciculus; ILF = inferior longitudinal fasciculus; MD = mean diffusivity; MdLF = middle longitudinal fasciculus; RD = radial diffusivity; SLF = superior longitudinal fasciculus; TOI = tract of interest; UF = uncinate fasciculus.
