摘要: A nonionic contrast enhancing agent for magnetic resonance. In a preferred embodiment chelating agent, example, EDTA or DTPA, binds metal, preferrably Gd, having at least one unpaired electron. Any carboxoyl groups not involved in chelation are bound to reduced lower carbohydrate between 3 and 5 carbon atoms. Such compositions useful the of Magnetic Resonance images.
