Typical and atypical PET/CT findings in non-cancerous conditions. Hell J Nucl Med. 2020 Mar 31;: Authors: Altini C, Lavelli V, Ruta R, Ferrari C, Nappi AG, Pisani A, Sardaro A, Rubini G Abstract Nuclear Medicine multimodality imaging, such as positron emission tomography/computed tomography PET/CT, refers to metabolic tissue characteristics integrated with anatomical details. Fluorine-18-fluorodeoxyglucose (18F-FDG) is the most diffuse radiopharmaceutical and its application is spreading beyond the area of oncology. The causes of high 18F-FDG uptake that were once considered false positives have been identified and the new knowledge about them led to non-cancerous pathologies that can be studied by 18F-FDG PET/CT. This technique, due to the inflammatory cells high avidity of 18F-FDG, can be useful in studying a variety of inflammatory and infectious systemic conditions. Studies performed in patients with fever of unknown origin (FUO) indicate that 18F-FDG PET/CT offer a great advantage of detecting malignancy, inflammation and infection at the same time both in adults and children. Furthermore, the 18F-FDG PET/CT has proved useful in the study of specific organs such as the heart and brain that represent separate topics also for the development of new specific radiopharmaceuticals. In all the non-oncologic conditions 18F-FDG PET/CT imaging may offer an "all-in-one" procedure, thanks also to its panoramic whole-body acquisition, as an...
