目的探讨多层螺旋CT(MSCT)在支气管内膜结核诊断及治疗评价中的应用价值。方法回顾性分析32例经纤维支气管镜证实的支气管内膜结核的CT轴位图像表现,并对在工作站获取的薄层图像分别进行多平面重建(MPR),CT仿真内窥镜(CTVE),表面遮盖(SSD)3种方法后重建。结果共有49处气管受累,主支气管2例,右主支气管4例,左主支气管3例,右肺上叶支气管15例,左肺上叶支气管12例,右中叶支气管4例,右肺下叶支气管5例,左肺下叶支气管4例。CT表现为支气管阻塞12例,支气管腔狭窄18例,支气管壁增厚13例,支气管壁钙化6例,伴肺门及纵隔淋巴结钙化27例。结论多层螺旋CT多种重建方法的结合应用,可以明确显示病变的发生部位及支气管腔狭窄或阻塞,有利于支气管内膜结核的诊断及治疗评价。
Objective To investigate the value of multi-slice spiral CT (MSCT) in the diagnosis and treatment of bronchial tuberculosis. Methods The CT axial images of bronchial endocardial tuberculosis confirmed by fiberoptic bronchoscopy were retrospectively analyzed. The images of multi - planar reconstruction (MPR), CT virtual endoscopy (CTVE) Surface Covering (SSD) 3 ways to reconstruct. Results A total of 49 tracheoespheres were involved. There were 2 cases of main bronchus, 4 cases of right main bronchus, 3 cases of left main bronchus, 15 cases of upper right bronchus, 12 cases of left upper lobe bronchi, 4 cases of right middle lobe, Bronchial in 5 cases, left bronchus in 4 cases. CT showed bronchiectasis in 12 cases, 18 cases of bronchial stenosis, bronchial wall thickening in 13 cases, bronchial wall calcification in 6 cases, with hilar and mediastinal lymph node calcification in 27 cases. Conclusion The combined application of multiple reconstruction of multi-slice spiral CT can clearly show the site of lesion and stenosis or obstruction of the bronchial lumen, which is good for the diagnosis and treatment evaluation of endobronchial tuberculosis.
