Abstract:
Objective To evaluate the applied value of MSCT lung volumes measurement in diagnosing chronic obstructive pulmonary disease(COPD).Methods 40 patients clinically diagnosed with COPD and 26 healthy volunteers as control group underwent MSCT chest CT scanning . The relevant indicators of lung volumes were measured and calculated in comparison with the indicators of clinical lung function . The accuracy and sensitivity of every indicator of lung volumes in forecasting and screening COPD by using ROC curve method were evaluated.Results There were significant differences between the control group and the COPD group in the full expiration volume(Vex),the full inspiration volume(Vin),Vex/Vin and the ratio of the change of lung volume(P
