Motivation: Structural MRI data enables cerebellar nuclei delineation, but small errors in registration to diffusion MRI data can hinder cerebellar brain connectivity analysis.
Goal(s): Our goal is to provide an accurate deep cerebellar nuclei segmentation method employing diffusion MRI data.
Approach: We employ several MRI contrasts to train a deep neural network to segment the deep cerebellar nuclei and assess their performance.
Results: Diffusion MRI spherical mean data enable to segment the deep cerebellar nuclei with improved precision.
Impact: Diffusion MRI spherical mean should be considered as a relevant image contrast for cerebellar structure segmentation using deep neural networks towards an increasingly accurate connectivity analysis.
