New contrast agents may be on horizon for better medical imaging
"Research by Kenneth Watkin, a professor in the department of speech and hearing science and the Beckman Institute for Advanced Science and Technology, may lead to the development of a new breed of “multimodal” contrast agents that could work within a host of medical imaging platforms – from ultrasound and computed tomography (CT) to magnetic resonance imaging and molecular imaging. In their work with gadolinium oxide nanoparticles, Watkin and McDonald started by breaking nanoparticles down into even smaller particles. Next, they successfully coated the particles with dextran, a naturally occurring carbohydrate."
