Conjugates for medical imaging comprising carrier, targeting moiety and a contrast agent

摘要

This invention relates to the delivery of agents to the body. One particular class of such agents are contrast agents useful in medical imaging techniques. The agents may be metals useful as contrast agents in magnetic resonance imaging (MRI), or in nuclear imaging, including positron emission tomography (PET), or as therapeutic agents in radiotherapy. The agents may alternatively be contrast agents useful in X-ray imaging. The invention also relates to methods by which agents for delivery to the body can be coupled to carriers and to targeting moieties effective to direct the agent to a specific locus within the body.
