胸部CT平扫及气道三维重建对小儿闭塞性细支气管炎的诊断价值

Diagnostic value of chest CT scan and three dimensional reconstruction of airway in children with bronchiolitis

目的:研究胸部CT平扫及气道三维重建对小儿闭塞性细支气管炎的诊断价值。方法:选取31例小儿闭塞性细支气管炎患儿作为研究对象分别对其进行胸部CT的平扫和气道三维重建进行诊断,观察两种诊断方法的诊断价值情况。结果:以MRI诊断作为金标准,CT平扫诊断小儿闭塞性细支气管炎的灵敏度为64.5%(20/31),特异度为67.7%(21/31),准确度为66.1%(41/62),显著低于气道三维重建诊断的灵敏度90.3%(28/31),特异度87.1%(27/31),准确度88.7%(55/62),差异有统计学意义(P<0.05)。结论:气道三维重建对于小儿闭塞性细支气管炎患者具有较高的诊断价值,能够为该病的治疗提供数据支持。

Objective To study the diagnostic value of chest CT scan and airway three-dimensional reconstruction in children with bronchiolitis.Method 31 children with bronchiolitis obliterans were selected as the object of study,chest CT plain scan and three-dimensional airway reconstruction for diagnosis,respectively,observation of the diagnostic value of two diagnostic methods.Results MRI diagnosis was used as gold standard,the sensitivity was 64.5%（ 20/31） and specificity was 67.7%（21/31）,and the accuracy was 66.1%（41/62）,which was significantly lower than that in the diagnosis of airway three-dimensional reconstruction of sensitivity 90.3%（28/31）,specificity 87.1%（27/31）,accuracy 88.7%（55/62）,and the difference was statistically significant（ P〈0.05）.Conclusion Airway three-dimensional reconstruction has high diagnostic value for pediatric patients with bronchiolitis,and can provide data support for the treatment of patients with the disease.
