鼻咽癌(NPC)患者局部侵犯情况的CT诊断与MRI诊断效果比较

摘要

Objective To compare the clinical efficacy of CT vs MRI in the diagnosis of local invasion of nasopharyngeal carcino-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-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-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.%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.
