Hydrophilic Nanocluster Contrast Agents for High Sensitivity Magnetic Resonance Imaging


Researchers from the University of Illinois have developed a new contrast agent for use with MRIs. The agent is made of super-paramagnetic iron oxide nanoparticles (SPIONs) with a special coating. This agent is an improvement over existing contrast agents and helps to increase the sensitivity of MRI scans. This is important, because it can define areas of damaged tissues which could go un-detected using currently available SPION-based contrast agents.
