I've found the article "Within-subject template estimation for unbiased longitudinal image analysis" by Reuter et al. It only examines a limited number of structures for the reproducibility of longitudinal Freesurfer. Are there any other paper that examines the cerebellum as well? Any suggestion from the authors of Freesurfer about accuracy of longitudinal Freesurfer for the cerebellum in healthy subjects?
