Abstract:
Objective To explore the application value of lung volumes from 64 multi-slice CT (MSCT) images in patients with chronic obstructive pulmonary disease (COPD) and study the correlation between lung volumes measured by MSCT and pulmonary function test (PFT) results. Methods 24 patients clinically diagnosed with COPD (COPD group) and 22 healthy people (control group) were selected and underwent both chest MSCT scans and PFT within one week. The total lung was scanned at full inspiration and full expiration with MSCT,respectively. The total lung volumes were measured by CT Pulmo software (Siemens,Forchheim,Germany). The quantitative total lung volumes from MSCT images were compared with PFT and SPSS13.0 was applied to assess the correlation. Results Compared with control group,the full inspiration volume (Vin) (P
