摘　　要：目的：为左肺下叶支气管的ＣＴ显示提供应用解剖学基础。方法：用３０具成人标本的支气管树及其中的１３例ＣＴ影像进行观测。结果：叶支气管内径５．０±０．６ｍｍ。段支气管内径２．４～３．１ｍｍ。Ｂ６、Ｂ７、Ｂ８、Ｂ９和Ｂ１０的夹角分别为８６．４°±５．４°、１８．１°±１．３°、１９．０°±２．２°、１７．０°±３．１°和２１．５°±３．１°。结论：本研究可为左肺下叶支气管的ＣＴ诊断增加一个以数据为依据确定管腔狭窄或管壁增厚的方法。Objective:To provide the applied anatomic basis for CT demonstration in left lower lobar bronchus.Methods:Thirty bronchial trees of adult cadaver specimens were studied,and 13 CT images of them were observed.Results:The internal diameters of lobar bronchus and segmental bronchi were 5.0±0.6 mm and 2.4±3.1 mm separately.The angles of B 6,B 7,B 8,B 9 and B 10 were 86.4°±5.4°,18.1°±1.3°,19.0°±2.2°,17.0°±3.1° and 21.5°±3.1° respectively.Conclusions:Left lower lobar bronchus stenosis or bronchus wall thickness could be diagnosed by CT image based on these data.
