摘要
目的:总结气管支气管内膜结核的多层螺旋CT表现,评价多层螺旋CT在支气管内膜结核诊断中的价值。方法:对36例经纤支镜证实的气管支气管内膜结核患者行多层螺旋CT扫描,结合多种影像后处理技术,分析其影像学表现,重点观察支气管管腔和管壁的形态学改变。结果:多层螺旋CT轴位及其三维重建图像能明确显示支气管管腔变窄、管腔表面不光滑、腔内结节状突起以及管壁增厚、密度增高、僵直和钙化。轴位图像还可显示肺内伴随表现。结论:多层螺旋CT扫描结合多种后处理技术可以有效地提高支气管结核的诊断率,是临床上一种无创性评价气管支气管病变的有效方法。
Objective：To summarize multi-slice spiral CT （MSCT） manifestations of endotracheal and endobronchial tuberculo- sis,and evaluate the diagnostic value of MSCT in endotracheal and endobronchial tuberculosis. Methods： Volume scanning with MSCT was performed in 36 patients with endotracheal and endobronchial tuberculosis proved by fibrous endoscopy examina- tions. The imaging findings, especially the morphologic changes of the lumen and wall of trachea and bronchi were analyzed. Results： The transverse image with post-process images could show the lumen and wall changes. The lumen changes included narrowing, coarse surface and intraluminal nodule . The wall changes included thickening, increased density, rigidity of the wall and calcified foci. The associated characteristics of lung were revealed in axial images. Conclusion： It is helpful to diagnose endobronchial tuberculosis with multiple functions of multi-slice spiral CT. It is a noninvasive and effective method for evalua- ting endotracheal and endobronchial tuberculosis.
