Early 2′-Deoxy-2′-[18F]Fluoro-d-Glucose PET Metabolic Response after Corticosteroid Therapy to Differentiate Cancer from Sarcoidosis and Sarcoid-like Lesions

Purpose We aimed at investigating whether early metabolic response to corticosteroid therapy may be used as a diagnostic tool to discriminate between cancer and sarcoidosis, a well-known cause of false-positive 2-deoxy-2-[F-18]fluoro-d-glucose-positron emission tomography (FDG-PET) findings in oncology.
