摘要
目的：为给ＣＴ对右肺下叶作斜位扫描提供倾斜角度及对诊断提供参考数据。方法：以３０例标本制成支气管树和１３例ＣＴ影像观测叶、段支气管内径、段支气管与叶支气管的夹角。结果：叶支气管内径５．０±０．２ｍｍ。相邻底段支气管内径无显著差别。ＢⅥ、ＢⅦ、ＢⅧ、ＢⅨ和ＢⅩ的夹角分别为８８．１°±１．７°、１８．２°±３．５°、２０．２°±２．８°、１５．８°±２．６°和１６．７°±３．６°。结论：叶段支气管内径、管壁厚度可为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以提高中心型肺癌的正确诊断率，依段支气管的倾斜角度将ＣＴ机架和体位作相应的倾斜和偏移使扫描层面与段支气管垂直可提高其ＣＴ显示率。
Objective:To provide the anatomy data for obilque CT scan of right inferior lobar bronchus. Methods:The angles between segmental bronchi and lobar bronchi and the interior diameter of them were observed on 30 bronchial trees and 13 CT images.Results:The interior diameter of lobar bronchus was 5.0±0.2 mm.The angles between lobar bronchus and BⅥ,BⅦ,BⅧ,BⅨ,BⅩ were 88.1°±1.7°,8.2°±3.5°,20.2°±2.8°,15.8°±2.6°and 16.7°±3.6° separately.Conclusions: The normal data of interior diameters and angles of the bronchus is helpful for the diagnosis of pulmonary cancer and for adjusting the scanning posture to make a clear CT image.
