目的:研究肺下缘的Ｘ线影像解剖学表现。方法:临床钡餐检查者中,随机选５４０例(有心肺疾患者除外),对其膈区的动态透视、摄片和电视录像资料进行观察分析,观测肺下缘的位置、形态、动度等。结果:肺下缘显示在双膈区呈一条下突的弧形线,称肺下缘线,是含气的肺下缘组织与周围结构的密度不同而显示的一条分界线。该线随呼吸活动,左右同步,平静呼吸时在肩胛肿线处平１１肋,双侧等高。活体肺下缘的位置比解剖学肺下缘的投影要低得多,两者相差约一个肋间。结论:肺下缘线是肺下缘的Ｘ线影像标志,观测肺下缘的影像对膈区疾病的诊断有重要意义。
Objective: To study the X-ray anatomy of the lower edge of the lung. Methods: In clinical barium meal examination, 540 cases were randomly selected (except those with cardiopulmonary diseases). The dynamic fluoroscopy, radiography and video recording of the diaphragmatic area were observed and analyzed. The position, shape and movement of the lower edge of the lung . Results: The lower edge of the lung showed a downward convex curve in the diaphragm area. The lower edge of the lung was the boundary line between the lower lung tissue with gas and the density of the surrounding structures. The line with respiratory activity, about synchronization, calm breathing in the scapular line at the flat 11 ribs, bilateral contour. The location of the lower edge of the living lung is much lower than the projection of the lower edge of the lungs of the anatomy, which differs by about one intercostal space. Conclusion: The lower edge of the lung is the X-ray image sign of the lower edge of the lung. The observation of the image of the lower edge of the lung is of great significance for the diagnosis of the disease in the diaphragm.
