The Role of 18F-FDG-PET and PET/CT in Patients with Sarcoidosis

FDG-PET and PET/CT seem to be useful in staging, evaluating disease activity, and monitoring treatment response in patients with sarcoidosis. PET appears to have higher diagnostic accuracy compared to Gallium-67-citrate scintigraphy. Conversely, there is not enough evidence about the use of other PET tracers in patients with sarcoidosis. FDG-PET and PET/CT seem to have a role as predictive tools and may influence the clinical management in patients with sarcoidosis, but more studies are needed in this regard.
