Magnetic Resonance Imaging (MRI)
Do not use a full body radio-frequency (RF) coil or other extremity coils on patients with a deep brain stimulation system. Because energy from MRI can be transferred through the implanted system, the potential for heat generation at the location of the electrodes exists. This isolated temperature rise may cause tissue damage at the location of the implanted electrodes, possibly resulting in severe injury or death. Injury can occur during MRI treatment whether the deep brain stimulation is turned on or off. All patients should inform there health care professional that they should not be exposed to MRI.
