Abstract
Substantially homogeneous aqueous suspensions of low density microspheres are presented as contrast media for imaging the gastrointestinal tract and other body cavities using computed tomography. In one embodiment, the low density microspheres are gas-filled. With computed tomography, the contrast media serve to change the relative density of certain areas within the gastrointestinal tract and other body cavities, and improve the overall diagnostic efficacy of this imaging method.
Claims10
A kit for computed tomography imaging of the gastrointestinal region or other body cavities comprising low density biocompatible synthetic polymeric or copolymeric microspheres having an internal void volume of at least about 75% of the total volume of the microsphere, and a thickening or suspending agent.
