摘要：
This invention relates to imageable polymers, particularly those comprising poly vinylalcohol and to methods for making them as well as to embolic microspheres comprising the polymers. The microspheres are imageable during embolization procedures and can be loaded with drugs or other therapeutic agents to provide an imageable drug delivery system.
