what is fdg
FDG (fludeoxyglucose F-18) is an intravenously administered radiopharmaceutical (radioactive drug) used to help diagnose certain medical problems.DG (fludeoxyglucose F-18) is an intravenously administered radiopharmaceutical (radioactive drug) used to help diagnose certain medical problems.
Fludeoxyglucose (18F) (INN), or fludeoxyglucose F 18 (USAN and USP), also commonly called fluorodeoxyglucose and abbreviated [18F]FDG, 18F-FDG or FDG, is a radiopharmaceutical used in the medical imaging modality positron emission tomography (PET).lthough in theory all 18 F-FDG is metabolized as above with a radioactivity elimination half-life of 110 minutes (the same as that of fluorine-18), clinical studies have shown that the radioactivity of 18 F-FDG partitions into two major fractions.
