Abstract
The invention relates to certain substituted derivatives of aminopolycarboxylic acids and metal chelates thereof. The compounds are particularly suitable for use as diagnostic agent. For example, the compounds can be used as radiodiagnostic agents, detoxification agents and contrast agents for diagnostic imaging processes. In particular, the high relaxivity paramagnetic metal chelates of substituted aminopolycarboxylic acids are especially suited for use as magnetic resonance imaging contrast agents.
