Cold barium suspensions have been shown to reduce primary esophageal peristalsis and improve distention of the lower esophagus and esophagogastric region. Cold barium is a useful adjunct to the standard radiographic examination when adequate distention of the esophagus has not initially been achieved. It is particularly applicable to evaluation of reflux esophagitis and esophageal strictures and rings.
冷钡剂混悬液已被证明可减少原发性食管蠕动，并改善食管下段及食管胃区域的扩张。当最初未能实现食管充分扩张时，冷钡剂是标准放射学检查的有用辅助手段。它特别适用于反流性食管炎以及食管狭窄和环的评估。
