Bisphosphonate-Associated Jaw Osteonecrosis and PET Imaging

Is to review medical records of approximately 1000 patients with bisphosphonate-associated ONJ who have had PET imaging at the time of diagnosis. Also to review medical records of patients who have been diagnosed with jaw osteomyelitis, osteoradionecrosis, and cancerous lytic lesions who received PET imaging at the time of diagnosis.
