The segmental air esophagogram (SAE) is an incidental finding in normal and abnormal frontal chest radiographs. It recognition is important to the proper radiologic analysis of the mediastinum, and examples are presented to illustrate its variable appearance in healthy and diseased patients. The authors observe that the SAE may occur less frequently in patients with carcinoma of the thoracic esophagus.
节段性充气食管造影（SAE）是在正常和异常胸部正位X线片上的偶然发现。其识别对于纵隔的正确放射学分析很重要，并给出了实例以说明其在健康和患病患者中的不同表现。作者观察到SAE在胸段食管癌患者中可能较少出现。
