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 the imaging features and diagnostic accuracy of X-ray and chest CT in patients with central lung cancer complicated with obstructive pulmonary disease (COPD) to guide clinical selection of appropriate imaging modalities. Methods Sixty-one patients with central lung cancer complicated with obstructive pneumonia diagnosed by fiberoptic bronchoscopy, surgical puncture or sputum exfoliative cell pathology were selected from June 2008 to June 2013 and were examined by X-ray and chest CT imaging The imaging characteristics and diagnostic coincidence rates of the two imaging methods were observed and compared. Results The diagnostic accuracy rate of chest X-ray was 72.1%, and the coincidence rate of chest CT was 93.4%. The diagnostic accuracy of chest CT was higher than that of X-ray, The difference was statistically significant (P <0.05). Conclusion The imaging characteristics of patients with central lung cancer complicated with obstructive pneumonia are complicated. The coincidence rate of chest CT examination is high, and should be selected reasonably in clinic.
