Abstract:
Objective To explore the feasibility of evaluating the lung function by MSCT in emphysema.Methods The MSCT scan and pulmonary function tests(PFF)were respectively performed in 147 receptors within one week.They were randomly divided into 2 groups:group A(120 receptors), including normal,mild,moderate and severe abnormal pulmonary function based on the PFT,for comparing the correlation between pulmonary quantitative indexes of MSCT pulmonary function and PFT and settingup the primary grade criteria of abnormal pulmonary function in emphysema,group B(27 receptors)for evaluating the diagnostic accuracy in group A.The total lung was respectively scanned at the full inspiration and full expiration with MSCT.The pulmonary quantitative indexes of MSCT were measured with Siemens Pulmo pulmonary quantitative software.Results There was correlation between pulmonary quantitative indexes of MSCT and PFF.The Piex/in_(-910)showed best correlation with FEV_1%(r=-0.905,P
