safety of MRI following bypass surgery
Is it safe to have an MRI procedure following bypass surgery? I understand there are metal wires used to repair the sternum and am concerned about the MRI magnet.
There is some concern with implanted devices such as pacemaker, etc. causing failure of the device. Foreign bodies are also potential risks, and safety aspects need to be considered on an individual basis. Interaction of the magnetic and radio frequency fields with such objects can lead to trauma due to movement of the object in the magnetic field, thermal injury from radio-frequency induction heating of the object. If there were a problem, it would be due to induction heating.
