摘要
目的探讨电子计算机断层扫描(CT)结合核磁共振(MRI)诊断中心型肺癌的价值观察。方法选取2017年9月~2019年4月确诊的56例中心型肺癌住院患者与同期就诊的50例肺部良性肿瘤患者为研究对象,采用回顾性分析法,以纤支活检或手术后进行病理组织学诊断为金标准,将中心型肺癌患者术前CT、MRI检测结果与病理诊断结果进行对比,判定CT、MRI单项检测与联合检测的阳性检出率、阴性检出率、准确率、灵敏度及特异度。结果 CT与MRI联合检测的阳性检出率、阴性检出率与CT、MRI单项检测无显著差异(P>0.05);CT与MRI联合检测的漏诊率为0.94%,低于CT与MRI单项检测的6.61%、1.89%(P<0.05);CT与MRI联合检测的误诊率为1.89%,低于CT与MRI单项检测的14.15%、8.49%(P<0.05);CT与MRI联合检测的准确诊断率为96.23%,高于CT与MRI单项检测的80.19%、89.62%(P<0.05);CT与MRI联合检测的敏感度为94.74%,高于CT与MRI单项检测的78.95%、87.72%(P<0.05);CT与MRI联合检测的特异度为97.96%,高于CT与MRI单项检测81.63%、91.84%(P<0.05)。结论 CT结合MRI能对中心型肺癌的浸润程度、淋巴结转移程度及管腔狭窄阻塞程度有较精准的诊断,可作为中心型肺癌早期诊断的有效方法,为临床治疗及干预方案提供参考,具有应用价值。
Objective To investigate the value of computed tomography(CT) combined with magnetic resonance imaging(MRI) in the diagnosis of central type lung cancer. Methods A total of 56 patients with central type lung cancer diagnosed during the period from April 2017 to December 2018 and 50 patients with benign lung tumors who were diagnosed during the same time period were selected as the research objects. Retrospective analysis was performed, and histopathological diagnosis after bronchoscopy biopsy or surgery was taken as the golden standard. The diagnostic results of CT and MRI were compared with pathological diagnosis results. The positive detection rates, negative detection rates, accuracy rates, sensitivities and specificities of CT and MRI alone and combined detection were determined. Results There was no significant difference in the positive detection rate or negative detection rate between combined detection and alone detection of CT and MRI(P>0.05). The missed diagnosis rate of CT combined with MRI(0.94%) was lower than that of CT or MRI alone(6.61%, 1.89%)(P<0.05). The misdiagnosis rate of CT combined with MRI combined detection(1.89%) was also lower than that of CT or MRI alone(14.15%, 8.49%)(P<0.05). The accuracy of CT combined with MRI(96.23%) was lower than that of CT or MRI alone(80.19%, 89.62%)(P<0.05). The sensitivity of CT combined with MRI(94.74%) was lower than that of CT or MRI alone(78.95%, 87.72%)(P<0.05). The specificity of CT combined with MRI(97.96%) was lower than that of CT or MRI alone(81.63%, 91.84%)(P<0.05). Conclusion CT combined with MRI can accurately diagnose the degree of invasion, lymph node metastasis and luminal stenosis of central type lung cancer. It can be used as an effective method for early diagnosis of central type lung cancer, providing references for clinical treatment and intervention.
