摘要
目的:通过对经临床证实的24例阴性支气管异物的螺旋CT图像的分析,旨在提高螺旋CT对阴性支气管异物的临床应用价值。方法:回顾性分析资料完整的均进行透视、平片、螺旋CT扫描,最后经支气管镜取出得以证实为阴性支气管异物的24例资料。结果:本组资料包括右主支气管12例,右中间支气管4例,右下叶支气管1例,左主支气管4例,左上叶支气管2例,左下叶支气管1例。其中20例阴性异物显示支气管腔内的软组织密度影,肺窗示支气管腔狭窄及连续性中断。单纯横断面扫描异物检出率为88%,结合MPR后可达95%。结论:螺旋CT扫描在阴性支气管异物的诊断中具有独特优势。
Objective To analyze spiral CT imaging of clinically proved negative bronchial foreign body and aim at improving the value of spiral CT in the diagnosis. Methods Twenty four cases with negative bronchial foreign body were confirmed by bronchoscopy. All patients were examined with fluoroscopy radiography and spiral CT the materials were analyzed retrospectively. Results The data included right main bronchial foreign body 12 cases right middle bronchial foreign body 4 cases right inferior lobar bronchial foreign body 1 case left main bronchial foreign body 4 cases left superior lobar bronchial foreign body 2 cases left inferior lobar bronchial foreign body 1 case 20 cases with negative bronchial foreign body manifested as soft tissue masses in bronchus and the lung windows showed bronchial stenosis and loss of continuity of the bronchus. The incidence of negative bronchial foreign body in cross sectional scan was 88% and was 95% after combined with MPR. Conclusion Spiral CT has unique advantage in the diagnosis of negative bronchial foreign body.
