Dear AuntMinnie Member,
OK, this may sound weird, but we don't envy the U.S. Food and Drug Administration (FDA) right now. The agency is facing intense pressure to act on the issue of gadolinium retention from MRI contrast agents, but so far there are no peer-reviewed studies in the literature indicating that gadolinium retention actually hurts patients.
That's not to say there hasn't been a chorus of concern about the issue. From patient advocates to MRI safety experts, voices have been raised, expressing alarm that traces of gadolinium are being found in patients long after their MRI exams were performed -- in some cases years later. European regulators have even recommended that three gadolinium agents be taken off the market.
But the FDA doesn't want to act until it has stronger evidence of harm. So it's examining the issue in a meeting of its Medical Imaging Drugs Advisory Committee tomorrow in Maryland. The committee will hear from industry members, clinicians, and patient advocates on the gadolinium retention issue, with the goal of answering several key questions that will form the agency's regulatory approach to gadolinium going forward.
