We explore the sensitivity of a morphometry tool to detect anorexia-related brain atrophy in MP2RAGE images. We compare volumetry resulting from two previously reported morphometry strategies on 16 patients with clinical suspicion of anorexia and identify both similarities and differences in brain atrophy evaluation.
