From: Clinical value of whole-body PET/CT in patients with active rheumatic diseases
18 F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) images at diagnosis and after steroid and tocilizumab treatment in a patient with adult-onset Still's disease (AOSD). (A1, B1, and C1) Marked FDG accumulation was observed in the bone marrow, spleen, and multiple lymph nodes at diagnosis. (A2, B2, and C2) After treatment, FDG uptake decreased in these sites - bone marrow, from SUVmax = 4.02 (A1) to 2.50 (A2); spleen, from SUVmax = 6.05 (A1 and C1) to 4.38 (A2 and C2) - as well as in multiple lymph nodes, including in the axilla, mediastinum, hilar region of the lung, hilar region of the liver, and para-aortic region (B1/C1 → B2/C2). SUV, standardized uptake value.
