At present, the detection of retropharyngeal lymph node (RLN) metastasis in nasopharyngeal carcinoma (NPC) mainly depends on imaging, but the diagnosis criteria are controversial. Recently, the 18F-fluoro-2-deoxy-D-glucose positron emission tomography ((18)FDG-PET-CT) has been widely applied in diagnosing cancer. This study was to evaluate CT, MRI, and (18)FDG-PET-CT in detecting RLN metastasis of NPC, and explore the imaging diagnosis criteria.
