Staging of head and neck tumors: [18F]fluorodeoxyglucose positron emission tomography compared with physical examination and conventional imaging modalities.

Purpose: The aims of this study were to evaluate the use of [(18)F]fluorodeoxyglucose positron emission tomography (FDG-PET) in the staging of primary and recurrent tumors of the head and neck in comparison to routine clinical methods (physical examination, ultrasonography, computed tomography) and to investigate the effect of FDG-PET scanning on therapeutic strategy.

Materials And Methods: Retrospective analysis of the results of FDG-PET and conventional diagnostic modalities were compared with biopsy results or patient outcome or both. In a period of 6 years, 78 FDG-PET studies were performed on 56 patients; 24 of them before therapy and 54 on suspicion of residual or recurrent tumor.
