Dear reader, since you choose to block our ads, please click here to help support Medgadget. In recent years, the use of both magnetic resonance imaging (MRI) 1 and the use of pacemakers (PMs) for treatment of cardiac arrhythmias, have been increasing. We may therefore limit the time we spend scanning a patient and limit the kinds of images we acquire. Cardiac Loop Recorders typically contain no lead wires or large loops of electrically conductive material. DeBus B. If you placed a wire within that alternating magnetic field, it could generate current and heat up. If you have any device implanted in your chest or body, it’s safe for you to have a CT scan. While not a safety hazard, patients should be made aware of this before scanning. “We worry about the heart muscle being burned, which could potentially turn into scar tissue,”Dr. Vogl H.
