Various types of intravascular and other types of coils, stents, and filters have been evaluated for safety with MR systems. Several of these demonstrated magnetic field interactions in association with scanners. Fortunately, the devices that exhibit positive magnetic field interactions typically become incorporated securely into the vessel wall primarily due to tissue ingrowth within approximately six to eight weeks after implantation. Therefore, it is unlikely that any of these implants would become moved or dislodged as a result of exposure to static magnetic fields of MR systems operating at 1.5Tesla or less.
