: In sarcoidosis progressive pulmonary disease affects prognosis. Pulmonary disease activity estimated by classic means poorly predicts severity and progressiveness. F-fluoro-2-deoxyglucose-positron-emission-tomography computed-tomography (F-FDG-PET/CT) estimates pulmonary activity by inflammatory-cells metabolism. We...
