OUTLINE: Patients are required to fast for a minimum of 6 hours prior to positron emission tomography (PET) imaging. Fludeoxyglucose F 18 (FDG) is administered IV over 15 minutes followed 50-60 minutes later by whole body PET imaging. Iodinated contrast dye is administered by IV injection and by mouth followed by CT imaging of the chest, abdomen, and pelvis within 2 weeks of PET imaging. Whole body FDG PET imaging and CT imaging of the chest, abdomen, and pelvis are repeated at 6 months. Initial positive PET or CT imaging results are verified based on surgical and/or biopsy findings or clinical follow-up.
