Researchers chide FDA: Pacemaker patients need not fear a CT scan

All of the Big Three devicemakers have worked to get their pacemakers certified compatible with MRI scans, but it doesn't look like they'll need to undertake similar efforts to ensure their patients will be safe in a CT scan. A team of researchers from the University of Maryland published results Wednesday of a clinical investigation into the FDA's 2008 advisory that CT imaging might interfere with pacemakers and implantable cardioverter-defibrillators. According to the researchers' findings, published in the Journal of the American College of Cardiology, that just doesn't happen. The original 2008 advisory--and a 2013 update--called for a physician to be present during CT scans of patients with cardiac devices. "The presence of cardiac devices should not delay or result in cancellation of clinically indicated CT imaging procedures," senior author Dr. Timm-Michael Dickfeld said in a statement.
