“…18 F-FDG is a glucose analog radiolabeled with fluorine-18 (18F), reflecting the glucose consumption and therefore, whole-body 18F-FDG PET/CT studies can produce a whole-body metabolic map of the patient [5]. An increased glucose uptake is one of the major metabolic features found in cancer cells, making 18F-FDG the most used PET-tracer for oncologic purposes [5,14,24].…”
