Tractometry is a hot topic in population analysis that combines diffusion MRI metrics along white matter bundles. Using a dataset of 11 healthy subjects with 3 different acquisitions collected within the same week, and a state of the art processing pipeline that removes outliers and splits bundles in separate parts by computing their centroid, we perform a test-retest study which validates that tractometry results are reproducible in terms of shape, volume, average metric value, and tract profiles.
