Comparison of diagnostic value between ~(18)F-FDG PET/CT and MRI in nasopharyngeal carcinoma / 吉林大学学报(医学版)

ABSTRACT

Objective To determine whether the use of 18F-FDG PET/CT alters staging and management of nasopharyngeal carcinoma (NPC) when compared with MRI staging practice;and to explore the relation of standard uptake value (SUV) of 18F-FDG PET/CT and the pathological classification and T staging of NPC. Methods The study was performed retrospectively on a group of 41 patients with a new diagnosis of NPC. All the patients underwent whole body PET/CT scanning and head & neck MRI scanning within 3 weeks of each other. The AJCC protocol was introduced to stage NPC and the results of the PET/CT were compared with MRI based on pathologic diagnosis. Results ①Primary tumorthe accuracy of T staging of PET/CT was significantly higher than MRI (85.37% vs 60.98%,U=2.49,P
