Improved Polymeric Contrast Agents for Roentgenologic Examination of the Gastrointestinal Tract

II. Preliminary Report on Animal Investigations

Abstract

A new improved water-soluble polymeric contrast agent has been studied in animal experiments. On oral and intraperitoneal administrations in mice, this polymer was found to have a very low toxicity. The contrast agent was used in connection with the roentgenologic examination of the gastrointestinal tract of dogs with good results. Further improvements are possible.
