a Typical FDG–PET/CT findings in a patient with PMR. High FDG uptake seen in PMR-specific sites, including cervical and lumbar interspinous bursae, shoulders, sternoclavicular, and hip joints, greater trochanters, and ischial tuberosities. b FDG–PET/CT in a 50-year-old woman with ovarian cancer. Strong FDG uptake in the ovary (arrowhead). Weak FDG uptake in the shoulders but not in any other PMR-specific sites
