[Application of 18F-FDG PET/CT scan in following-up of nasopharyngeal carcinoma after radiotherapy].

Background & Objective: Local relapse,tumor residue, and whole body metastases of nasopharyngeal carcinoma (NPC) after radiotherapy were mainly confirmed by CT, MRI, SPE/CT, and PET examinations. This study was to discuss the value of F-18-fluoro-2-deoxy-d-glucose positron emission tomography/computed tomography (PET/CT) in detecting suspected recurrence or tumor residue, and whole body metastases of NPC after radiotherapy.

Methods: PET/CT were performed on 38 NPC patients 3-36 months after radiotherapy.
