Abstract

Abstract A method for imaging the Gl tract and the intestinal wall is described. The method comprises administering to a mammal a low density contrast medium comprising an oil in water emulsion containing from about 2 to about 50 percent by volume oil, and obtaining images of the GI tract and the intestinal wall. Also described is a low density contrast medium comprising an oil.in water emulsion containing from about 2 to about 50 volume percent oil and a predetermined amount of soluble salts or sugars to maintain homeostasis in the intestine.
