Objective To explore the diagnostic value of CT quantitative detection in chronic obstructive pulmonary disease (COPD). Methods A total 113 patients with suspected COPD who were hospitalized an outpatient department a hospital from January 2018 to December 2020 selected as subjects study. All underwent examination, lung function and other related examinations. The results examination used gold standard detect COPD, application diagnosis was analyzed. Results Among 157 C0PD, 112 (71.34%) 20 (12.74%) bronchial asthma; forced expiratory volume (FEV,), vital capacity (FVC) FEV,/FVC value, mean density (MLD) lumen area (LA) first second group lower than those non-COPD group. respiratory biphasic voxel index<- 950HU accounted for percentage [VI-950 (%)] wall (WA%) higher group, difference statistically significant (P<0.05); bivariate Spearson correlation test showed that negatively correlated VI-950 WA% (r<0, P<0.05), positively MLD LA (r>0, P<0.05); ROC curve show AUC VI-950, MLD, LA, by rCT is more 0.7, which has high predictive value. When best threshold obtained, can be obtained. Conclusion efficiency differential provide objective reference clinical early examination.
