Abstract： 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3 mm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27处(19.8%);支气管不均匀狭窄96处(70.6%).病变发生在主支气管31处(22.8%);叶支气管81处(59.6%);段支气管24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,与纤维支气管镜有很强的互补性.
