Magnetic Resonance Imaging (MRI) – Patients with an implanted device should not be exposed to the electromagnetic fields produced by magnetic resonance imaging (MRI). Use of MRI may potentially result in system failure, dislodgement, heating, or induced voltages in the neurostimulator and/or lead. An induced voltage through the neurostimulator or lead may cause uncomfortable, “jolting,” or “shocking” levels of stimulation. Clinicians should carefully weigh the decision to use MRI in patients with an implanted neurostimulation system, and note the following:

• Magnetic and radio-frequency (RF) fields produced by MRI may change the neurostimulator settings and injure the patient.
• Patients treated with MRI should be closely monitored and programmed parameters verified upon cessation of MRI.
