[In vitro tests of barium sulphate suspensions for double contrast examinations of the stomach (author's transl)].
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.
