Are MRIs safe for patients with pacemakers?
The 2 million Americans with implanted pacemakers or defibrillators are warned to avoid strong magnetic currents, especially MRIs. Cardiologist Dr. Robert Russo believes, though, that carefully-controlled MRIs can be done and he's launched a study to test his theory. If he's correct, his study could have widespread impact since more than half of people with the devices are likely to need an MRI someday. Ref. Source 7
