What is FDG?
FDG is a type of glucose and is the most commonly used tracer in PET. To begin the PET procedure a small amount of glucose is injected into a patient’s bloodstream. There is no danger to you from this injection. Glucose is a common substance that every cell in your body needs in order to function. Diabetic patients need not worry; it would take 1,000,000 doses of FDG to equal the glucose in 1 teaspoon of sugar. FDG has a half-life of approximately 110 minutes, so it is quickly expelled from your body. FDG must pass multiple quality control measures before it is used for any patient injection.
FDG (Fluoro Deoxyglucose is a type of glucose (sugar) and is the most commonly radiopharmaceutical used in PET. To begin the PET procedure a small amount of glucose is injected into a patient’s bloodstream. There is no danger to you from this injection. Glucose is a common substance that every cell in your body needs in order to function. Diabetic patients need not worry; it would take 1,000,000 doses of FDG to equal the glucose in 1 teaspoon of sugar. FDG has a half-life of approximately 110 minutes and is excreted by way of the kidneys, so it is quickly expelled from your body. FDG must pass multiple quality control measures before it is used for any patient injection.

2-Deoxy-2-[18F]fluoro-D-Glucose, or FDG, is a type glucose (sugar) and is the most common radiopharmaceutical used in PET. To begin the PET procedure, a small amount of glucose is injected into your bloodstream. There is no danger to you from this injection.

FDG is basically a radioactive sugar. FDG refers to Fluorine-18 FluoroDeoxyGlucose, the most common radiotracer used in clinical PET-CT imaging today. An FDG molecule consists of two parts – the radioactive component Fluorine-18, and glucose, the sugar component that is recognized by your body. Fluorine-18 is a radionuclide that emits positrons, and therefore can be detected by a PET-CT scanner. Prior to your PET-CT scan, a small amount of FDG is injected intravenously into your body. Because it is made from a sugar molecule, FDG distributes throughout your body based on the metabolic activity of the various organs and tissues. Fluorine-18 decays quickly, and within a few hours is no longer significantly radioactive. For this same reason, it is very important that you arrive for your scan at your scheduled appointment time.
