Patient (case # 16) with a history of right total hip arthroplasty performed 16 years before imaging. The results of 18F-FDG PET/CT (upper row) and 68Ga-citrate PET/CT (lower row) are presented. ad Green arrows indicate an intense 18F-FDG uptake surrounding the cup and the proximal part of the hip prosthesis stem components. On CT images, osteolytic changes and the presence of residual cement in the right acetabulum were evident. Cup loosening with synovial hypertrophy and clear joint fluid were detected during surgery. 18F-FDG PET/CT findings were therefore classified as false positve. df Findings on 68Ga-citrate PET/CT were true negative, without any obvious radiotracer accumulation at the corresponding sites. h Plain film
