Getting Better Visualization Of Joint Cartilage Through Cationic CT Contrast Agents

A new computer tomography (CT) contrast agent for visualizing the spatial distribution of glycosaminoglycans -- the anionic sugars that account for the strength of joint cartilage -- was found by a team of chemists, engineers and clinicians recently. Assessing local variations in GAGs are of significant interest for the study of cartilage biology and the diagnosis of cartilage diseases like osteoarthritis, which afflicts more than 27 million people in the US.
