What is a radiopharmaceutical?
A radiopharmaceutical is a radioactive drug. The most commonly used PET radiopharmaceutical is FDG, which is a radioactive form of glucose (sugar). Radiopharmaceuticals are produced by physicists and chemists. WHAT IS FDG? FDG is a type of glucose (sugar) and is the most common radiopharmaceutical used in PET imaging. To begin the PET procedure, a small amount of glucose is injected into your 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 do not need to 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. HOW DO I PREPARE FOR A PET/CT SCAN? Nothing to eat or drink for at least 4 hours prior to appointment time. (Be sure to drink plenty of fluids up to that point. This will make insertion of your IV easier.) Notify x-ray scheduling at 724-543-81
