When we used thalamic volume (the most discriminating GM measure) together with the white matter lesion volume, the accuracy of the classification of MS vs NMO was 80%. The classifications of MS vs HCs and NMO vs HCs achieved higher accuracies (92% and 88%).Conclusions: GM imaging biomarkers, automatically obtained from clinical scans, can be used to distinguish NMO from MS, even in a 2-center setting, and may facilitate the differential diagnosis in clinical practice.Classification of evidence: This study provides Class II evidence that GM imaging biomarkers can distinguish patients with NMO from those with MS.AQP4-Ab=aquaporin-4 autoantibody; EDSS=Expanded Disability Status Scale; FLAIR=fluid-attenuated inversion recovery; GM=gray matter; HC=healthy control; LPBA=LONI Probabilistic Brain Atlas; MS=multiple sclerosis; NMO=neuromyelitis optica; NMOSD=neuromyelitis optica spectrum disorder ER -
