Fluorodeoxyglucose, known as FDG, is a key component in most PET scans, enabling detailed insights. This article will explain the composition of FDG, its function during a PET scan, the diagnostic information it yields, and what a patient can expect during the procedure.
F]FDG is now the standard radiotracer used for PET neuroimaging and cancer patient management. [4] The images can be assessed by a nuclear medicine physician or radiologist to provide diagnoses of various medical conditions.
FDG stands for Fluorodeoxyglucose, a radioactive glucose compound used extensively in PET scanning. FDG is a glucose analog that is tagged with a radioactive tracer. This combination allows it to highlight areas of metabolic activity in the body when viewed under a PET scan.
What Is an FDG PET Scan? A fludeoxyglucose-18 (FDG) positron emission tomography (PET) scan is an imaging test that is commonly used to look for cancer in the body. These PET scans use a substance, called a radiotracer, to highlight areas of activity within the body that are suggestive of cancer.
FDG, or Fluorodeoxyglucose F 18, is a radioactive tracer. It is a molecule that closely resembles regular glucose, the body’s primary sugar source. Cells readily take up glucose for energy, and FDG mimics this natural process, allowing its absorption by cells with high metabolic activity.

FDG is a glucose analog, meaning it closely resembles glucose, the sugar molecule that cells use for energy. When FDG is injected into the bloodstream, it accumulates in areas of high metabolic activity, such as rapidly growing cancer cells or inflamed tissues.
