Because of uncertainty regarding safety, some manufacturers of coronary artery stents have recommended waiting a period of 8 weeks after stent placement before magnetic resonance imaging (MRI). Of 211 patients imaged by MRI within 2 weeks after either bare metal or drug eluting stent placement, none had serious adverse cardiac events. Fifteen of the 211 patients were imaged within 24 hrs of stent placement. It appears safe and feasible to perform MRI early after coronary stent placement using a wide variety of stents.
