通过对59例临床及X线表现疑为气管支气管结核患者行CT检查，采用常规CT机扫描，层厚5mm，层距5mm，诊断气管支气管结核32例。对照先导支气管纤维键及临床，误诊3例，CT诊断准确率89．8％。其中CT表现为：（1）气管支气管狭窄或营垒增厚;（2）管腔闭塞；（3）合并肺内结核灶；（4）有肺门及纵隔淋巴结核证据。常规CT诊断气管支气管结构简便易行，诊断准确率高，是一种较为优良的诊断方法。
59 cases of clinical and X-ray findings of suspected tracheobronchial tuberculosis patients underwent CT examination, the use of conventional CT scanning, layer thickness 5mm, layer spacing 5mm, the diagnosis of tracheobronchial tuberculosis in 32 cases. Control pilot bronchial fiber key and clinical misdiagnosis in 3 cases, CT diagnostic accuracy rate of 89.8%. Which CT showed: (1) tracheobronchial stenosis or camp thickening; (2) lumen occlusion; (3) combined with pulmonary tuberculosis; (4) hilar and mediastinal lymph node evidence. Conventional CT diagnosis of tracheobronchial structure is simple and convenient, high diagnostic accuracy, is a relatively good diagnostic method.
