Non-clinical testing at field strengths greater than 3 Tesla has not been performed to evaluate stent migration or heating. Although the authors blamed the MRI for the displacement, subsequent letters to the editor cast doubt on this assertion, providing evidence that the original stent was poorly chosen and placed and that spontaneous displacement of similarly placed stents had been reported in the absence of MRI. Non-covered stents may be bare (metal only) or impregnated with a medication (so-called drug . Keywords.
