You should know that FDG (fludeoxyglucose F-18) is an injection used to enhance visualization in the three-dimensional medical imaging technology called PET (positron emission tomography). FDG contains a small amount of radiation that reportedly does not threaten your health. The PET scan helps in the diagnosis, staging and monitoring Hodgkin's disease, non-Hodgkin's lymphoma and several cancers and other disorders of the brain, heart and lungs.

Before receiving FDG, ask your doctor if you need to fast for a number of hours because blood sugar needs to be within certain limits. The following conditions may interfere with FDG's ability to help diagnose certain medical problems: urinary tract blockage, menstruation, diabetes and anxiety. If you are pregnant or nursing, be sure to discuss with your doctor the possible risks and benefits of receiving FDG. Before receiving FDG (or any other drug) make sure your doctor has your complete medical history. It should include: all prescription and over-the-counter drugs you take, as well as herbal supplements. Also, tell your doctor about any food, drug or other allergies.
