Difficulties in evaluating the gastric cardia are well known and may often be resolved with the double-contrast technique. Special views to show the cardia en face were obtained in 200 double-contrast examinations. Four basic patterns were recognized. Similar appearances could be reproduced by protruding or retracting the lower end of the esophagus during the radiography of intact stomachs obtained at autopsy. Influenced by muscle relaxants, swallowing, or deep breathing, cardia patterns were found to be interchangeable in the same patient and same examination. The disappearance of the protrusion pattern at the cardia in the course of swallowing is an important means of distinguishing normality from a tumor in this area. Any significant deviation from the normal geometry of the cardia as displayed by double contrast indicates an abnormality. Examples of abnormalities are illustrated.
评估贲门存在困难是众所周知的，而双对比技术常常可以解决这些困难。在200例双对比检查中获得了显示贲门正面的特殊视图。识别出了四种基本模式。在尸检获得的完整胃的放射摄影过程中，通过突出或缩回食管下端可以重现相似的表现。受肌肉松弛剂、吞咽或深呼吸的影响，发现在同一患者的同一检查中贲门模式是可以互换的。吞咽过程中贲门突出模式的消失是区分该区域正常与肿瘤的重要手段。双对比显示的贲门正常形态的任何显著偏差都表明存在异常。文中给出了异常情况的示例。
