CT诊断中心型肺癌的准确性及磁共振成像补充诊断的意义评价

Evaluation of the accuracy of CT diagnosis of central lung cancer and the clinical significance of magnetic resonance imaging supplementary diagnosis

目的探讨CT诊断中心型肺癌的准确性及磁共振成像（MRI）补充诊断的意义，为临床诊断提供参考。方法选择陵川县医疗集团总院2015年1月至2017年10月诊治的疑似中心型肺癌患者30例为观察对象，患者均采用CT检查、MRI检查，以术后病理检查结果为标准，观察CT检查结果和MRI检查结果，分析对CT诊断患者使用MRI补充检查的价值。结果经术后病理诊断显示，30例疑似中心型肺癌患者中，25例患者被确诊为中心型肺癌，5例为良性肿瘤。cT对中心型肺癌的诊断敏感性、特异性、准确率分别为68．0％、20．0％、60．0％。MRI补充诊断后，对中心型肺癌的诊断敏感性、特异性、准确率分别为92．0％、80．O％、90．0％。结论CT诊断中心型肺癌的准确率偏低，为保证诊断的准确率，有必要对患者实施MRI补充诊断。

Objective To investigate the accuracy of CT in the diagnosis of central lung cancer and the clinical significance of magnetic resonance imaging（MRI） supplementary diagnosis, in order to provide reference for clinical diagnosis. Methods From January 2015 to October 2017,30 patients with suspected central lung cancer treated in General Hospital of Lingchuan County Medical Group were selected in the research. All patients were examined by CT and MRI, and the results of pathological examination were taken as the standard. The results of CT and MRI were observed and the value of MRI supplementary examination in CT diagnosis was analyzed. Results The sensitivity,specificity and accuracy of CT in the diagnosis of central lung cancer were ＇68.0% ,20.0% and 60.0%, respectively. After MRI imaging supplementary diagnosis, the diagnostic sensitivity, specificity and accuracy of diagnosis of central lung cancer were 92.0%, 80.0% and 90. 0%, respectively. Conclusion The accuracy of diagnosis of central lung cancer by CT is low. In order to ensure the accuracy of diagnosis,it is necessary to carry out MRI supplementary diagnosis to the patients.
