目的:探讨多层螺旋CT在支气管、肺外伤诊断中的诊断价值,并与X线胸片比较来选择最佳检查方法。方法:回顾性分析19例胸部外伤患者的CT表现,主要分析支气管和肺组织损伤的表现。结果:根据CT表现将肺损伤分为轻中重三度,其中轻度5例,2例X线胸片漏诊;中度6例,X线胸片显示病变较CT显示的范围小,程度轻;重度8例,其中3例X线胸片漏诊部分病变。支气管损伤2例,X线胸片均不能清晰显示,经螺旋CT薄层扫描,并行三维重建后处理可清晰显示病变。结论:胸部创伤的急诊检查,不能满足于X线胸片的粗略显示,还应重视多层螺旋CT检查。
Objective: To investigate the diagnostic value of multislice spiral CT in the diagnosis of bronchial and pulmonary trauma, and to compare with X-ray to choose the best method. Methods: CT findings of 19 cases of chest trauma were retrospectively analyzed. The main manifestations of bronchial and lung injury were analyzed. Results: According to the CT findings, the lung injury was divided into mild, moderate and severe third degree, of which 5 were mild and 2 were missed by X-ray; 6 were moderate and X-ray showed lesser extent than CT, ; Severe in 8 cases, of which 3 cases of missed diagnosis of chest X-ray lesions. Bronchial injury in 2 cases, X-ray can not be clearly displayed by thin-layer spiral CT scan, parallel three-dimensional reconstruction of post-processing can be clearly displayed lesions. Conclusion: The emergency examination of chest trauma can not be satisfied with the rough display of X-ray and should pay attention to multi-slice spiral CT.
