Although many models have been proposed to interpret
non-Gaussian diffusion MRI data in biological tissues,
it is often difficult to see the correlation between the
MRI data and the histological changes in the tissue. In
this work, a statistical model based on the gamma
distribution is proposed. Using this model, the
diffusion MR data is well fitted, and histological
interpretation of the data is possible.
