The Spatially-Constrained Incoherent Motion (SCIM) model
aims to improve the quality of the fast and slow
diffusion parameter estimates by utilizing a spatial
homogeneity of the signal decay parameters as an
informative prior to guide the estimation, and
effectively estimates parametric maps representing the
signal decay model using the Fusion Bootstrap Moves
(FBM) solver. Here, we aim at evaluation of the SCIM
model on improving the robustness of fast and slow
diffusion parameter estimates in the ileum against
acquisition protocols that utilize different choices of
b-values.
