【摘要】 目的探讨肺癌患者空气贮留与肺功能指数的相关性。方法对57例病理确诊为肺癌患者,使用螺旋CT分别进行了不同呼吸时相的连续容积数据模式扫描,对空气贮留进行评分,全部患者作了肺功能检查。结果肺癌患者空气贮留与小气道功能指标FEF25%(r=-0.51,P<0.05),FEF50%(r=-0.77,P<0.01)、RV(r=0.75,P<0.01)高度相关,与FEV1(r=-0.20,P>0.05)、FVC(r=-0.19,P>0.05)、FEV1/FVC(r=-0.35,P>0.05)不相关。结论肺癌患者的空气贮留与小气道功能指标有密切相关性。更多还原

【Abstract】 Objective To analyze the correlations between air-trapping and pulmonary functional indexes in patients with lung cancer. Methods 57 patients were diagnosed as lung cancer by pathology and scanned by spiral CT at the end inspiration and expiration with continuous volume scan mode. Expiration scans were scored at a lobar level for the areas of air-trapping. All the patients were performed pulmonary function tests ( PFT) . Results The small airways’functional indexes were negatively correlated with total air-trapping scores in FEF25% ( P < 0. 05) ,FEF50% ( P < 0. 01) and were positively correlated with RV ( P < 0. 01) . But there was no correlation in FEV1( P > 0. 05) ,FVC( P > 0. 05) ,FEV1 /FVC( P > 0. 05) . Conclusion There is a close correlation between air trapping and small airways’functional indexes in patients with lung cancer.更多还原
