摘　　要：目的:比较CT和MRI对鼻咽癌临床分期的差异和探讨MRI在鼻咽癌临床分期中的应用价值。方法:2006年8月至2008年2月,广西医科大学病理确诊的鼻咽癌患者102例,放疗前1周内以同一固定体位,完成增强CT和增强MRI。CT和MRI上分别读片判定鼻咽癌临床分期。结果:相对于CT检查,MRI使41.18%(42/102)病例的’92福州分期的T分期发生改变,其中23.53%(24/102)为升级,17.65%(18/102)为降级;使26.47%(27/102)病例的UICC/AJCC分期的T分期发生改变,其中20.59%(21/102)为升级,5.88%(6/102)为降级。N分期CT和MRI一致。结论:对于鼻咽癌局部T分期的准确确定,MRI比CT更有价值;对于N分期,CT和MRI一致。Objective： To compare the diference between the clinical staging of nasopharyngeal carcinoma determined by CT and MRI and to explore the value of MRI in determining the clinical stage of nasopharyngeal carcinoma （NPC）. Methods： Between August 2006 and Feburary 2008, 102 cases of squamous cell carcinoma of NPC treated in the First Affiliated Hospital of Guangxi Medical University were enrolled in the study. Before treatment, CT,MRI and 1SFDG -PET-CT scanning were performed.Film reading of CT and MRI was conducted to determine the clinical stage.Results： Compared with CT, MRI made the T stage change in 41.18% cases （42/ 102） （including 23.53%（24/102） up-staging and 17.65%（18/102） down-staging） for the Chinese ＇92 staging system, while made the T stage change in 26.47% cases（27/102） （including 20.59%（21/102） up-staging and 5.88% （6/102） down-staging） for the 6th edition UICC/AJCC staging system. Conclusion： MRI has obvious advantage in determining the T stage of nasopharyngeal carcinoma. In determining the N stage of nasopharyngeal carcinoma, CT is same as MRI.
