摘要
目的:为左、右肺上叶、段支气管及右肺中叶、段支气管的CT显示提供解剖学基础。方法:用30具成人标本的左、右肺支气管树及其中左、右肺各13例CT影像进行观测。结果:左、右肺上叶支气管及右肺中叶支气管的内径分别为5.2±0.6mm、5.1±0.9mm和4.0±0.6mm。段支气管内径为2.3~2.6mm。左肺B1+2、B3的夹角分别为182.8°±3.6°和92.0°±5.0°;右肺B1、B2、B3、B4和B5的夹角分别为173.8°±14.3°、92.2°±2.0°、81.5°±4.5°、40.5°±10.1°和45.5°±11.0°。结论:可为CT诊断提供一个以数据为依据确定支气管异常的方法,通过调整段支气管与CT扫描层面间的夹角,可提高斜位CT扫描显示率。
Objective:To provide anatomic basis for CT demonstrations of the superior and middle lobar bronchi.Methods: Bronchial trees of 30 adult cadavers and 13 CT images were observed and measured.Results:The internal diameters of the left and right superior and right middle lobar bronchi are 5.2±0.6 mm,5.1±0.9 mm and 4.0±0.6 mm respectively.The angles of LB 1+2 and LB 3 is 182.8°±3.6° and 92.0°±5.0°. The angles of RB 1,RB 2,RB 3,RB 4 and RB 5 is 173.8°±14.3°, 92.2° ±2.0°,81.5°±4.5°,40.5°±10.1° and 45.5°±11.0° respectively.Conclusions:These data may provide datums for CT by the way to adjust angles between segmental bronchi and CT sices.
