Currently, there are minimal data regarding the magnetically induced displacement force of coronary artery stents, in 7.0 T MR. We tested a range of commonly implanted coronary artery stents for maximal displacement force at 7T. CoCr stents appear to have safe deflection properties at 7T. However 316L-SS and PtCr stents exhibit increased magnetically induced displacement forces, and may be not be considered conditionally safe at 7.0T
