Abstract
Polymers are increasingly employed in implant materials. To reduce the incidence of complications, which in the case of vascular grafts include incorrect placement and restenosis, materials are needed which allow for image-guided implantation, as well as for accurate and efficient postoperative implant imaging. We here describe amorphous fluorinated polymers based on thermoplastic polyurethane ((19)F-TPU), and show that are useful starting materials for developing tissue-engineered vascular grafts which can be detected using (19)F MRI.
