Volume based morphometry is a well-established tool to investigate changes of brain structures in neurodegenerative diseases, and a variety of implementations is available. With MRI investigations as an indispensable instrument for diagnosis and disease progress monitoring, the question about reliability and robustness of these tools arises. This work examines the accuracy of CAT 12 and FreeSurfer by comparing a selection of their calculated subcortical volumes to a ground truth.
