Answer

Some studies have suggested that whole body F(18)-fluorodeoxyglucose positron emission tomography (FDG-PET) scanning appears to be of additional value to assess inflammatory activity in patients with persistent symptoms in the absence of signs of serological inflammatory activity and to detect extrathoracic lesions. [48] Whole-body FDG-PET scanning is of value in identifying occult and reversible granulomas in patients with sarcoidosis. [49, 50]
