【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。更多还原

【Abstract】 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.更多还原
