摘要

Objective: This study was designed to explore the diagnostic value of multi-slice spiral CT (MSCT) scanning in lung compression ratio of patients with pulmonary contusion complicated by pneumothorax or hydropneumothorax. Methods: Seventy-eight patients with pulmonary contusions complicated by pneumothorax or hydropneumothorax treated in the Department of Emergency Surgery of our hospital were examined by CT and X-ray, and the diagnostic value of these two methods was observed. The correlation of lung compression ratio measured by multiplanar reconstruction (MPR) and volume rendering (VR) with W/D ratio was studied, and the formula between VR-measured lung compression ratio and W/D ratio was constructed using a one-variable linear regression equation. Results: The diagnostic rate of pulmonary contusions complicated by pneumothorax or hydropneumothorax measured by CT was higher than that by X-ray (P0.05). Among the patients with pulmonary contusion diagnosed by CT, 45 were localized and 33 were extensive, and there were statistically significant differences in the incidence of comorbid rib fractures (P0.05). The correlation of lung compression ratio measured by VR with W/D ratio measured by CT was analyzed, and the regression equation of the two was obtained by one-variable linear regression equation analysis: lung compression ratio =1.159* W/D -1.034. VR-measured lung compression ratio measured was positively correlated with W/D ratio (r=0.936, P0.001). Conclusion: CT is superior to X-ray in the diagnosis of pulmonary contusions complicated by pneumothorax or hydropneumothorax. The calculation of lung compression ratio using the formula of lung compression ratio =1.159* W/D -1.034 has certain clinical value and can improve clinical work efficiency.
