Abstract

The strengths and potential pitfalls of fluorodeoxyglucose positron emission tomographic (FDG-PET) imaging in patients with head and neck cancer, especially those who have undergone surgery and/or chemotherapy and irradiation, is reviewed. PET is performed using the radiopharmaceutical [18F]-FDG, a D-glucose analog. The increased vascularity of tumors and glucose metabolism by malignant cells result in preferential uptake of FDG by tumor cells. The inability to process metabolites of the modified glucose molecule causes intracellular accumulation of 18F-containing radioisotopes. This metabolism has been invaluable in the evaluation of many cancer patients, and PET plays a pivotal role in the diagnosis, staging, and restaging of head and neck oncology patients. The ability to assess the functional status of tissue with FDG-PET has been remarkable and addresses this well-known limitation of conventional cross-sectional computed tomographic (CT) and magnetic resonance (MR) imaging.
