Abstract
Novel contrast media for use in magnetic resonance imaging are described. Such contrast media are comprised of biocompatible polymers either alone or in admixture with one or more contrast agents such as paramagnetic, superparamagnetic or proton density contrast agents. Additionally, the polymers or polymer and contrast agent admixtures may be mixed with one or more biocompatible gases to increase the relaxivity of the resultant preparation, and/or with other components. In a preferable embodiment, the contrast medium is hypoosmotic.
