Abstract: The present invention provides a silicon-based polymer contrast media for use in CT imaging. In an exemplary embodiment, the invention provides an enteric contrast medium formulation. An exemplary formulation comprises, (a) an enteric contrast medium comprising silicon-based polymer oil emulsified in water. Exemplary silicon-based polymer oil has a viscosity between about 50 cSt and 100,000 cSt. In various embodiments, the silicon-based polymer oil is emulsified with a vehicle or dispersing medium compatible with enteric administration of the formulation to a subject in need of such administration. In an exemplary embodiment, the contrast material is incorporated into a pharmaceutically acceptable vehicle in which the material is emulsified in the presence of a surfactant. In an exemplary embodiment, the silicon-based polymer comprises 30% or more of the weight of the contrast material formulation.
