From: Clinical value of whole-body PET/CT in patients with active rheumatic diseases
18F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) images at diagnosis and after steroid treatment in a patient with large-vessel vasculitis. (A) FDG-PET/CT at diagnosis identifies aortitis in the thoracic and abdominal aorta and arteritis bilaterally in the subclavian and axillary vessels as strong uptake in the walls of the aorta and arteries. (B) Update decreased markedly during steroid treatment.
