18F-FDG uptakes around left hip with osteoarthritis. a Coronal CT image of the left hip demonstrates joint space narrowing along the superior aspect of the left hip joint, compatible with mild-to-moderate OA. b Fused coronal 18F-FDG PET-CT image of the left hip shows hypermetabolic activity along the periphery of the left hip joint in the expected location of the synovium and joint capsule, compatible with synovitis associated with OA
