MR-SIGNAL EMITTING COATINGS

摘要

The present invention provides a coating that emits magnetic resonance signa ls and a method for coating medical devices therewith. The coating includes a paramagnetic metal ion-containing polymer complex that facilitates diagnosti c and therapeutic techniques by readily visualizing medical devices coated wit h the complex. The present invention also provides methods by which pre-existi ng polymers and medical devices may be made MR-imageable. The invention also provides methods of improving MR-imageability of polymers and medical device s by encapsulating the polymers and medical devices with hydrogels.
