Four barium sulphate suspensions were investigated with respect to their adhesion and contrast following standard means of spreading the contrast over a model stomach, which corresponds in its detailed structure with the surface of the gastric mucosa. By this means various factors, which make a true comparison in vivo impossible, could be eliminated and a comparison of the suspensions became possible. Using similar mechanical and chemical situations, the radiographs of the artificial mucosa showed very different results from the use of the different preparations. These corresponded well with the findings in vivo.
按照将造影剂均匀涂抹在模拟胃上的标准方法，对四种硫酸钡混悬液的粘附性和造影效果进行了研究。该模拟胃的详细结构与胃黏膜表面一致。通过这种方式，可以消除各种在体内无法进行真实比较的因素，从而实现混悬液之间的比较。在相似的机械和化学条件下，使用不同制剂时人造黏膜的X光片显示出截然不同的结果。这些结果与体内研究结果高度吻合。
