Multidimensional diffusion MRI reveals heterogeneous microstructural remodeling associated with amyloid pathology

Pak Or, Maxime Yon, Omar Narvaez, Valeriia Sitnikova, Tarja Malm, Mustapha Bouhrara, Alejandra Sierra, Daniel Topgaard, Dan Benjamini

This study uses multidimensional diffusion MRI to show increased microstructural heterogeneity in 5xFAD mouse brains compared to wild-type, associated with amyloid pathology but not widespread degeneration.
