Potential of 18 F-FDG-PET as a valuable adjunct to clinical and response assessment in rheumatoid arthritis and seronegative spondyloarthropathies

Figure 4 Assessment of treatment response in a patient of psoriatic arthritis. A: Pre treatment; B: Post treatment. The fluorodeoxyglucose-positron emission tomography lower-limb scan of a patient with psoriatic arthritis. Rest of the whole body survey was unremarkable. Same patient was followed and a response evaluation scan was performed 6 wk after specific treatment for psoriatic arthropathy. There was significant fall in maximum standardized uptake value values correlating to the clinical improvement in the patient.
