肺部慢性炎症与原发性肺癌供血动脉CTA表现的影像比较分析

The Comparison and Analysis of CTA Features of Chronic Inflammation of the Lungs and Primary Lung Cancer

目的对肺部慢性炎症与原发性肺癌供血动脉CTA的影像表现进行对比研究。方法以该院2010年1月—2014年10月收治的60例肺部慢性炎症患者作为慢性肺炎组、以30例原发性肺癌作为原发性肺癌组,所有患者均行64层螺旋CT扫描,以50例健康者作为对照组,对比3组研究对象的支气管动脉内径、慢性肺炎组与肺癌组的体外循环供血率。结果慢性炎症组、肺癌组与对照组的支气管动脉的内径差异均具有统计学意义。慢性炎症组肺体外循环动脉供血率为46.67%,肺癌组肺体外循环动脉供血率为16.67%,慢性炎症组显著高于肺癌组(P<0.05)。结论支气管动脉扩张普遍存在于肺部慢性炎症及原发性肺癌中,尤其肺部慢性炎症的支气管扩张更明显,两者的供血动脉CTA表现能够为临床鉴别诊断提供依据。

Objective Compare and analyze the CTA imaging features of chronic inflammation of the lungs and primary lung can-cer. Methods Select 60 cases with chronic inflammation of the lung from January 2010 to October 2014 as chronic inflammation of the lung group, select 30 cases with primary lung cancer as primary lung cancer group, and select 50 healthy controls as control group, compare the bronchial artery diameter of the three groups, and compare the extracorporeal circulation rate of blood flow of the chronic inflammation of the lung group and primary lung cancer group. Results The bronchial artery diameter of the three groups have statistical significance, P〈0.05. The extracorporeal circulation rate of blood flow of the chronic inflammation of the lung group is 46.67%, that of primary lung cancer group is 16.67%, the extracorporeal circulation rate of blood flow of the chronic inflammation of the lung group is much higher than that of primary lung cancer group （P〈0.05）. Conclusion Both of the chronic inflammation of the lung and primary lung cancer have bronchial artery expansion, and the chronic inflammation of the lung is more apparent. The CTA features of them can supply reference for clinical diagnosis.
