Simultaneous 18F-FDG PET/MR metabolic and structural changes in visual snow syndrome and diagnostic use

ConclusionPatients with VSS have highly significant structural and metabolic abnormalities in the visual and limbic system. VOI-based discriminant analysis of18F-FDG PET allows reliable individual classification versus controls, whereas visual analysis of experienced observers was highly variable. Further investigation in larger series, also in comparison to VSS mimicking disorders such as migraine, is warranted.Trail registration: Retrospectively registered at clinicaltrials.gov under NCT05569733 on Oct 5, 2022.
