慢性阻塞性肺疾病患者CT表现类型与肺功能检查指标的相关性研究

摘要

目的:对慢性阻塞性肺疾病者CT表现类型和肺功能检查指标相关性进行研究.方法:分析2014年10月至2016年10月慢性阻塞性肺疾病120例患者资料,据CT特点分M、E及A型,用CT图像检测像素指数,分析各分型像素指数及CT表现类型和肺功能检查指标相关性.结果:A型像素指数比M、E型低,E、A型像素指数和残气量/肺总量呈正相关(P<0.05).结论:临床分析CT表现类型和肺功能检查指标相关性可为慢性阻塞性肺疾病防治工作开展提供依据.%Objective:To study the correlation between CT manifestations and lung function in patients with chronic obstructive pulmonary disease. Methods:All the data of 120 patients with chronic obstructive pulmonary disease admitted in our hospital from October 2014 to October 2016 were analyzed. According to the CT characteristics of M, E and A model, with CT image pixel index, the analysis of each type pixel index and types of CT manifestations and lung function index correlation. Results:The pixel index of type A was lower than M, E. The pixel index and residual volume/total lung of type E, A were positively correlated ( P < 0. 05) . Conclusion:The clinical analysis of the correlation between CT expression and pulmonary function test can provide the basis for the prevention and treatment of chronic obstructive pulmonary disease.
