中心型肺癌并发阻塞性肺炎的影像学监测对比

Monitoring contrast of imaging of central lung cancer complicated with obstructive pneumonia

目的监测对比中心型肺癌并发阻塞性肺炎患者的X线胸片和胸部CT检查的影像学特征及诊断符合率,以指导临床选择合适的影像学检查方式。方法选取2008年6月至2013年6月间经纤维电子支气管镜、手术穿刺或痰脱落细胞病理检查确诊的中心型肺癌并发阻塞性肺炎患者61例,进行X线胸片和胸部CT影像学检查,观察并比较分析两种影像学检查方法的影像学特征和诊断符合率。结果在中心型肺癌并发阻塞性肺炎诊断不同病理分型和部位上,X线胸片诊断符合率为72.1%,胸部CT诊断符合率为93.4%,胸部CT诊断符合率高于X线胸片,差异有统计学意义(P<0.05)。结论中心型肺癌并发阻塞性肺炎患者的影像学特点复杂,胸部CT检查诊断符合率较高,在临床中应合理选用。

Objective To monitor and compare the imaging features of X-ray,chest CT and diagnostic accuracy in patients with central lung cancer complicated with obstructive pneumonia,to guide to select appropriate imaging methods in clinical practice. Methods From June 2008 to June 2013,61 cases of central lung cancer complicated with obstructive pneumonia diagnosed by electronic bronchoscope through the fibers,surgical biopsy or sputum cytology test methods and confirmed by pathology were enrolled into this study. All the patients were examined by chest X-ray and CT imaging,the imaging features and diagnostic accuracy were analyzed and compared. Results In the diagnosis of pathological type and location of center lung cancer complicated with obstructive pneumonia,the diagnostic accordance rate of X-ray and CT was 72. 1% and 93. 4%,respectively,the difference was significant（ P〈0. 05）. Conclusion The imaging features of central lung cancer complicated with obstructive pneumonia were complicated,the diagnostic accordance rate of chest CT is higher,in is worthy to be used in clinical practice.
