摘要：
Described herein are X-ray imageable polymers such as polymeric particles comprising bismuth as a radiopacifying agent, methods of making the polymers, and methods of using the polymers. The imageable particles may comprise a covalently bound compound which chelates the bismuth, for example, through a combination of nitrogen and oxygen atoms.
