Pulmonary 18F-FDG positron emission tomography and high resolution computed tomography in patients with early severe diffuse cutaneous systemic sclerosis. (A) No visual uptake of 18F-FDG was observed in a patient with systemic sclerosis without interstitial lung disease. (B) Increased uptake of 18F-FDG in the lungs of a patient with systemic sclerosis associated interstitial lung disease is indicated by the arrows. (C) Repeated 18F-FDG positron emission tomography in the same patient, who had severe progression of interstitial lung disease after 3 months of cyclophosphamide pulse treatment. Higher uptake of 18F-FDG was seen at the follow-up scan when compared to baseline.
