The FDA issued a warning today that the strong magnetic fields used in an MRI exam can affect implantable infusion pumps. The federal watchdog has received reports of serious adverse events, including patient death, associated with using an infusion pump in an MR environment. The reports claim that some patients have experienced inaccurate medication dosing and mechanical problems with the pump after having an MRI.
Only implantable infusion pumps that are labelled as “MR Conditional” are safe to use within an MR environment, and only under specific conditions, according to the FDA. To reduce the probability of a serious adverse event, the FDA recommends that patients tell their physicians and MR technician if they have an implantable infusion pump and be able to identify the make and model of the pump. The federal group also recommended that patients have their devices checked before and after the imaging procedure.
