Radiologic studies can be helpful when evaluating patients who are suspected of having esophageal motility disorders. Performing studies of the highest technical quality yields the most definitive results. The esophagus should be assessed for anatomic and functional abnormalities that may account for presenting symptoms. Motility disorders such as achalasia and scleroderma have specific radiographic findings that are described in this article; however, some motility disorders of the esophagus have nonspecific radiographic findings. In those cases, it is imperative that clinical and manometric information be combined with radiographic findings to provide accurate diagnoses. The radiographic examinations that are most commonly used include barium esophagography and nuclear medicine examinations. This article emphasizes the use of barium examinations to assess esophageal motility.
在评估疑似患有食管动力障碍的患者时，放射学检查可能会有所帮助。进行技术质量最高的检查可得出最明确的结果。应评估食管是否存在可能导致出现症状的解剖和功能异常。诸如贲门失弛缓症和硬皮病等动力障碍具有本文所述的特定放射学表现；然而，一些食管动力障碍具有非特异性放射学表现。在这些情况下，必须将临床和测压信息与放射学表现相结合以提供准确的诊断。最常用的放射学检查包括食管钡餐造影和核医学检查。本文重点介绍使用钡剂检查来评估食管动力。
