WebFeb 1, 2024 · Fludeoxyglucose F 18 injection is used to help diagnose cancer, heart disease, and epilepsy. It is used in a procedure called a positron emission tomography (PET) scan to help your doctor see parts of the body, such as the heart or brain. Fludeoxyglucose F 18 belongs to the group of medicines called radiopharmaceuticals (radioactive agents). Fluorine-18 is one of the early tracers used in positron emission tomography (PET), having been in use since the 1960s. Its significance is due to both its short half-life and the emission of positrons when decaying. A major medical use of fluorine-18 is: in positron emission tomography (PET) to image the brain and heart; to image the thyroid gland; as a radiotracer to image bones, looking for cancers that have metastasized from other locations in the body and in radiation therapy treatin…
