Mechanism of action

The drug consists of fluorodeoxyglucose (FDG), a glucose molecule with a fluorine-18 radioisotope attached. Cancer cells and inflamed tissues consume glucose at higher rates than normal tissue, causing FDG to preferentially accumulate in these areas. The fluorine-18 emits positrons that are detected by PET scanners, producing detailed metabolic images to identify and localize disease.
