POLYMER IODINATION FOR IMPROVED IN VITRO TRACKING OF BIODEGRADABLE STENT DEGRADATION: SERIAL MICROCT IMAGING FOR BIOREACTOR TESTING

Evaluating the in vitro degradation of a biodegradable magnesium (Mg) alloy stent by X-ray micro-computed tomography (CT) is made difficult by low attenuation of Mg and polymer coating. Addition of iodine (I) to polymer coating of Mg stents was investigated to improve segmentation of microCT images
