[Detection of residue of nasopharyngeal carcinoma with FDG PET].

Background And Objective: The use of F-18-fluoro-2-deoxy-d-glucose positron emission tomography (FDG PET) in detection of suspected residue of malignant tumor after treatment has become one of the most important targets of study in radiotherapy. This study was designed to evaluate FDG PET in detection of suspected residue of nasopharyngeal carcinoma (NPC) after treatment, in comparison with CT imaging.

Methods: Twenty-five patients with clinically suspected residue of NPC did FDG PET Scanning, 23 of them also examine with CT imaging.
