摘　　要：目的：探讨机架倾斜支气管侧后斜位CT扫描在支气管病变诊断中的价值。材料与方法：根据常规轴位显示的病变部位，取患侧近台的躯体与机架双斜位扫描设计，躯体向背侧、机架向尾侧倾斜25°-30°角包括主支气管、叶段支气竹区域于平静状态下屏气后逐层扫描。结果：共计检查病变55例，包括中央型肺癌27例，剧围型肺癌12例，支气竹内膜结核6例，炎性病变10例。均比常规轴位显示更多的诊断信息。结论：机架倾斜支气管侧后斜位CT扫描有利于补充常规轴位的不足，剥支气管及肺部病变的诊断和鉴别诊断有一定价值。Purpose： To investigate the evaluation of double oblique postural CT scanning in the diagnosis of pathological changes on bronchus. Materials and Methods： By conventional transverse scanning design including the diseased side proximal body and gantry, were tak- en. The oblique angle about body faced back side and the gantry the tail side was used 23°- 30°. The zones and lesions in bronchus and lobe segments were scanned in tranguil. Results： in 55 eases, 27 cases were central bronehogenie carcinoma, 12 eases were, peripheral lung cancer, 6 eases were endobronchial tubereolosis. 10 eases were inflamed affection. A1 showed much diagnostic information than that of eonventional transverse posture. Conclusion： Double oblique postural CT scanning is very helpful in completing shortage of eonventional transverse posture and was of great value in the diagnosis and differentiation of pathological changes on bronchus.
