From: Clinical value of whole-body PET/CT in patients with active rheumatic diseases
Typical18 F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) findings in a patient with rheumatoid arthritis (RA). (A) Maximum intensity projection and (B, C) axial FDG-PET/CT findings of RA in an 86-year-old woman presenting with polyarthritis. She was diagnosed with RA based on the presence of symmetrical polyarthritis that continued for more than 19 weeks with a severe inflammatory reaction (C-reactive protein, 12.72 mg/dL) and magnetic resonance imaging findings that showed synovitis and tendinitis. FDG-PET/CT showed (A) symmetrical arthritis and remarkable circular FDG uptake due to synovitis around the (B) shoulders and (C) hips.
