摘要
目的 探索多层螺旋CT的大范围薄层扫描及后处理功能对支气管结核的诊断价值。方法 选择临床诊断支气管结核和痰查结核菌阳性的病人 98例。用多层螺旋CT作 3mm层厚扫描 ,最小密度投影、计算机容积摄影、CT仿真内镜后处理。采用盲法诊断与纤维支气管镜及病理对照。结果 支气管结核的CT表现主要是支气管阻塞或狭窄。支气管阻塞 13处 (9 6% ) ;支气管均匀狭窄2 7处 (19 8% ) ;支气管不均匀狭窄 96处 (70 6% )。病变发生在主支气管 3 1处 (2 2 8% ) ;叶支气管 81处 (59 6% ) ;段支气管 2 4处 (17 7% )。同一病人多处受累者为 56例 (51 7% )。多层螺旋CT对支气管结核诊断的敏感度为 89 8% ;特异度为 63 2 % ;准确度为 84 6%。结论 多层螺旋CT多功能组合应用可以有效地提高对支气管结核的诊断率 。
Objective To explore the diagnostic value of multi-slice spiral CT with big field of view,thin slice thickness,and postprocessing in endobronchial tuberculosis Methods Ninety-eight clinically diagnosed and tuberculosis bacillus positive patients were included The multi-slice spiral CT was performed using 3 mm thickness scan,MiIP,CVR,and CTVE management The CT diagnosis was made by the single-blind method and was compared with fiberoptic bronchoscope and pathology Results Main CT features were as follows: obstruction of bronchia in 13 cases (9 6%),uniform stricture of bronchia in 27 cases (19 8%),and non-uniform stricture of bronchia in 96 cases (70 6%) The lesions located in the main bronchia in 31 (22 8%),pulmonary lobar bronchia in 81 (59 6%),and pulmonary segmental bronchia in 24 (17 7%),respectively Multiple lesions were found in 56 cases (51 7%) The sensitivity,specificity,and accuracy of multi-slice spiral CT in the diagnosis of endobronchial tuberculosis were 89 8%,63 2%,and 84 6%,respectively Conclusion The exertion of multiple functions of multi-slice spiral CT can increase the diagnostic level for endobrochial tuberculosis,and spiral CT is a good supplementary to fiberoptic bronchoscope
