Intra-class correlation coefficients (two-way mixed, absolute agreement) for test-retest repeatability of microstructure measures measured 5 times in 6 participants. ICC = intra-class correlation, CST = cortico-spinal tract, FA = fractional anisotropy, MD = mean diffusivity, RD = radial diffusivity, RSF = restricted diffusion signal fraction, MMPF = macromolecular proton fraction, MWF = myelin water fraction, R1 = longitudinal relaxation rate, MTR = magnetisation transfer ratio.
