Stochastic diffusion coefficient models. a Assumed probability distribution of the homogeneous effective diffusion coefficient \(D^{*}\) modelled as a random variable and used in Model D1. The expected value \(E[D^{*}]\) is \(1.2 \times 10^{-10}\,\hbox {m}^2\)/s. b Sample of the heterogeneous effective diffusion coefficient (sagittal, axial and coronal slices ordered from left to right) modelled as a random field and used in Model D2
