A comparison of two high-density barium sulphate preparations for double-contrast barium meals

The mucosal coating properties, liability to bubble formation and palatability of a new barium sulphate suspension (Micropaque HD) were compared with those of the barium suspension shown by previous trials to produce the best results (E-Z-HD). The results show that E-Z-HD gave significantly better mucosal coating and was less liable to bubble formation. There was no significant difference in the palatability of the two preparations.
