Benign incidental CT findings and corresponding metabolic changes in FDG PET/CT: A pictorial essay

1014 Learning Objectives 1. To emphasize the importance of systematically review the CT portion of the PET/CT scan. 2. To understand the FDG metabolic changes corresponding to benign CT detected abnormalities. 3. To avoid false positive interpretation of such abnormalities. 4. To implement an innovative way to display radiographic images using a digital media frame. PET/CT provides invaluable metabolic and anatomical information about known or suspected malignancy which will lead to treatment planning and patient outcome. Our PET/CT protocol includes a low dose non contrast CT. However, a full diagnostic contrast CT is used in some institutions which provide more detailed images and help in the assessment of the anatomical structures. The review of the CT can lead to the detection of incidental anatomical alterations, which can present with or without metabolic abnormalities and should be properly characterized by the reading physician to avoid a false positive interpretation. We are presenting a large series of benign incidental CT findings with metabolic changes and MRI and diagnostic CT correlation involving the head and neck (e.g. Brain infarct, carotid aneurysm ± thrombus pituitary adenoma, thyroid cyst), thorax (e.g. hiatal hernia, breast lipoma, esophagitis, thoracic aneurysm, granuloma), abdomen (e.g. AAA ± thrombus, pancreatic/liver/renal cysts , exofitic renal tumors, gastritis, pancreatitis), pelvis (e.g. uterine fibroids, ovarian cysts, menstrual changes in the uterus), and musculoskeletal (e.g. bone island, bone infarction, active osteoarthropathy, septic joint effusion, postsurgical changes). These radiographic images will be presented in an innovative high quality dynamic digital media frame which will be included in the body of the poster and will provide us with the advantage of presenting a higher quality and higher number of images, rotating MIPs, correlated coronal and saggital MRI and diagnostic CT images
