A stable colloidal suspension of barium sulfate has been developed and tested in roentgen examination of the gastrointestinal tract. The new material is rather distinctive in radiographic appearance and can usually be differentiated from simple barium-water mixtures by inspection of roentgenograms of the opacified stomach and small intestine. It usually affords a satisfactory demonstration of the mucosal folds of the stomach and duodenal bulb and is considerably more resistant to flocculation and precipitation by retained gastric secretions. In the small intestine, it has little tendency to undergo flocculation and fragmentation, and permits visualization of fine mucosal configurations with unusual clarity. Its motility is about the same as that of conventional suspensions. Air contrast colon examinations with the colloidal preparation exhibit a very uniform, opaque, and stable coating of the bowel wall and are more consistently satisfactory than when simple barium-water mixtures are used.
一种硫酸钡稳定胶体悬浮液已被研制出来并在胃肠道X线检查中进行了测试。这种新材料在X线影像上相当独特，通常通过观察胃和小肠显影的X线片就能与简单的钡水混合物区分开来。它通常能令人满意地显示胃和十二指肠球部的黏膜皱襞，并且对胃内潴留分泌物引起的絮凝和沉淀具有更强的抵抗力。在小肠中，它几乎没有絮凝和破碎的倾向，能够异常清晰地显示精细的黏膜形态。它的流动性与传统悬浮液大致相同。使用这种胶体制剂进行气钡双重对比结肠检查时，肠壁会呈现出非常均匀、不透光且稳定的涂层，比使用简单钡水混合物时更令人满意。
