摘要
目的探讨CT肺容积扫描诊断慢阻肺(chronic obstructive pulmonary disease,COPD)的临床意义。方法选取60例COPD患者为观察组,同期60例肺功能正常志愿者为对照组。两组均行螺旋CT肺容积扫描与常规肺功能检查,收集两种方法检测出的各项指标并且分析其相关性。结果观察组第1 s用力肺活量(FEV1%)和FEV1/FVC(%)均显著低于对照组(P<0.05),残气量(RV%)、肺总量(TLC%)、RV/TLC(%)以及3个肺气肿容积比例(E/L)指标均显著高于对照组(P<0.05)。FEV1%和FEV1/FVC(%)与3个E/L指标为显著负相关(P<0.01),而RV%、TLC%、RV/TLC(%)与3个E/L指标为显著正相关(P<0.01)。结论 CT容积扫描得到的肺容积指标与肺功能指标密切相关,其对COPD的诊断意义重大,值得临床进一步推广应用。
Objective To investigate the clinical significance of CT lung volume scanning in the diagnosis of COPD. Methods Sixty patients with COPD were selected as observation subjects. At the same time,60 healthy volunteers were selected as controls. Spiral CT pulmonary volume scanning and routine pulmonary function tests were performed in the two groups. The indicators detected by the two methods were collected, and the correlations were analyzed. Results The FEV1% and FEV1/FVC ( % ) in the observation group were significantly lower than those in the control group ( P 〈 0.01 ). The RV%, TLC%, RV/TLC ( % ) and E/L of the 3 indexes in the observation group were significantly higher than those in the control group ( P 〈 0. 01 ). FEV1% and FEV1/FVC ( % ) were negatively correlated with E/L index (P 〈 0. 01 )while RV% ,TLC% and RV/TLC (%)were positively correlation with E/L index (P 〈 0. 01 ). Conclusion The lung volume indicators observed by CT volume scanning is closely correlated with lung function indexes. Therefore ,'the scanning has an important diagnostic value for COPD. It is worthy of further clinical application.
