We investigate the effect of the inversion time on the spherical mean technique (SMT) and neurite orientation dispersion and density imaging (NODDI) metrics based on the multi-parametric diffusion MR data. Our findings indicate the orientation dispersion index and mean orientation of Watson distribution remains unchanged for a wide range of TI, while volume fractions and diffusivities show significant changes leading to characteristic "up-and-down" behavior concerning the TI used to fit the model.
