The effects of diffusion time on ADC and MD were controversial in previous studies. Moreover, the effect of the diffusion gradient strength has received little attention. In this study, a new experimental protocol is designed to evaluate the effect of the two parameters. The results show that the varying diffusion time or diffusion gradient strength produces a significant effect on MD, which could not be explained by previous theory.
