  • Title: [Improved radiological diagnosis in the stomach by means of an improved contrast material (author's transl)].
    Author: Lotz W, Liebenow S.
    Journal: Rofo; 1979 Aug; 131(2):157-65. PubMed ID: 157949.
    Abstract:
    Our experience with a cheap contrast medium, which we prepare ourselves, is described, stretching over a period of 18 months. It is based on the bubbly barium first described by Op den Orth and is made by means of carbon dioxide in a soda water syphon. It is better for detailed contrast examination of the stomach than the commercially available contrast media. It is thought that this is due to optimal viscosity for wetting of the mucosa, optimal size of the barium sulphate particles, which are larger than one micron, and greater distension of the stomach due to greater quantities of CO2. The use of bubbly barium for routine examination of the stomach, using double contrast and hypotonia with graded compression, almost always results in demonstration of the areae gastricae in large parts of the stomach. We regard this as a sign of a good examination, since we are then able to demonstrate small lesions such as complete or incomplete erosions, ulcer scars or flat ulcers.
