摘　　要：目的分析纵隔型肺癌CT及MRI的临床表现及诊断准确率。方法随机选取2014年5月-2016年5月收治的纵隔型肺癌患者84例,对所有患者进行DR拍片、CT及MRI检查,然后对其手术与病理学检查结果、临床表现及诊断准确率进行分析。结果 84例患者中,在肺癌类型方面,中央型肺癌50例,周围型肺癌34例,分别占总数的59.5%、40.5%;在发病部位方面,右肺上叶30例,右肺下叶26例,左肺上叶22例,左肺下叶6例,分别占总数的35.7%、31.0%、26.2%、7.1%;在病理类型方面,鳞癌42例,小细胞癌22例,腺癌20例,分别占总数的50.0%、26.2%、23.8%。CT、MRI检查的诊断准确率100.0%(84/84)、100.0%(84/84)均显著高于DR拍片检查81.0%(68/84)(P<0.05),但CT、MRI检查的诊断准确率之间的差异不显著(P>0.05)。结论纵隔型肺癌CT及MRI的临床表现不同,诊断准确率均显著高于DR拍片,临床可以将二者有机结合起来进行诊断。Objective To analyze the clinical manifestations and diagnostic accuracy of CT and MRI of mediastinum lung cancer. Methods 84 cases of patients with mediastinal lung cancer who were treated in our hospital from May2014 to May 2016 were randomly selected,all patients were given DR film,CT and MRI checks,and their surgical and pathological findings,clinical manifestations and diagnostic accuracy were analyzed. Results Among the 84 cases of patients,in terms of types of lung cancer,50 cases were central lung cancer,34 cases were peripheral lung cancer,accounting for 59. 5%,40. 5% of the total,respectively; in terms of disease sites,30 cases were in right upper lobe,26 cases were in right lower lobe,22 cases were in left upper lobe,6 cases were in left lower lobe,accounting for 35. 7%,31. 0%,26. 2%,7. 1% of the total,respectively; in terms of histological types,42 cases were squamous cell carcinoma,22 cases were small cell carcinoma,20 cases were adenocarcinoma,accounting for 50. 0%,26. 2%,23. 8% of the total,respectively. The diagnostic accuracy rate of CT,MRI,100. 0%（84/84）,100%（84/84） were significantly higher than the DR film 81. 0%（68/84）（P〈0. 05）,but the difference of diagnostic accuracy rates between CT,MRI was not significant（P〉0. 05）. Conclusions The clinical manifestations of CT and MRI of mediastinal lung cancer CT and MRI are different,the diagnostic accuracy are both significantly higher than DR film,the clinical can combine them for diagnosis.
