[摘要]目的探讨比较CT与MRI诊断鼻咽癌(NPC)患者局部侵犯情况的临床疗效。方法随机选取该院自2013年1月—2015年3月收治的80例鼻咽癌患者，所有患者均行CT与MRI检查并对结果进行分析，统计两种方法的检出率和淋巴结转移情况的判断结果。结果鼻咽部检查结果中，CT与MRI的检出率分别为35.0%和72.5%；颅底部检查结果中，CT与MRI的检出率分别为22.5%和57.5%，两组数据差异有统计学意义（P＜0.05）。在淋巴结的转移情况判断中，CT的准确性、敏感度和特异度均高于MRI，差异有统计学意义（P＜0.05）。结论CT与MRI诊断鼻咽癌(NPC)患者局部侵犯情况均有诊断效果，MRI的检出率相对较高，CT可查看淋巴结的转移情况，临床上应视患者的具体情况来做出最合适的治疗方案。

Abstract[]Objective To compare the clinical efficacy of CT vs MRI in the diagnosis of local invasion of nasopharyngeal carcino鄄ma (NPC).Methods 80 NPC patients admitted to our hospital between January 2013 and March 2015 were randomly selected.All patients underwent CT and MRI.The detection rate and lymph node metastasis were recorded and compared between the two ex鄄aminations.Results In terms of nasopharyngeal site, the detection rate of CT and MRI was 35.0% and 72.5% respectively; in terms of skull base, the detection rate of CT and MRI was 22.5% and 57.5% respectively, and the differences were statistically signifi鄄cant（P＜0.05）.In diagnosis of the lymph node metastasis, the accuracy, sensitivity and specificity of CT were higher than that of MRI, and the differences were statistically significant（P＜0.05）.Conclusion CT and MRI are both effect in the diagnosis of local invasion of NPC, and the detection rate of the latter is higher while the former is better in determining the lymph node metastasis.Therefore treatment plan should be made based on patients' detailed information.

鼻咽癌(NPC)是一种临床上常见的恶性肿瘤，主要采用放射治疗为主，因此，准确判断出肿瘤侵犯情况即具体大小位置等就显得尤为重要[1]，从而对病灶区有一个大致的把握。传统的载线检查或者造影技术无法对复杂的病灶进行准确的判断，从而临床上常用CT或者MRI来对患者进行检查，以便准确的显示病变部位的肿瘤侵犯情况[2]。该院随机选取2013年1月—2015年3月收治的80例鼻咽癌患者进行CT与MRI的检查效果对比，探讨比较CT与MRI诊断鼻咽癌(NPC)患者局部侵犯情况的临床疗效。……
