Positron emission tomography (PET) with fluorodeoxyglucose (FDG) allows the
visualization of metabolic tissue activity. Use of FDG in in-vivo cancer i
maging is based on enhanced glycolysis in tumor cells. In vivo experiments
have demonstrated the potential use of FDG PET in squamous-cell head and ne
ck tumors and the detection of tumor involvement in lymph nodes. Since its
introduction in this area, several papers have appeared on the use of this
imaging modality. Indications for the use of FDG PET in patients with head
and neck cancer are discussed. (C) 1998 Elsevier Science Ltd. All rights re
