What is Magnetic Resonance Imaging (MRI)?

MRI is a diagnostic technique that uses a magnetic field and radio waves to create high resolution detailed images of the organs and tissues within your body.

Patients and physicians should know the limitations, warnings and precautions associated with the StimRouter System and Magnetic Resonance Imaging (MRI). Patients with an implanted StimRouter Lead can be scanned safely, immediately after implantation, in MR cylindrical bore system that meets the specified conditions.

1.5 Tesla and 3 Tesla MRI Warning and Precautions:

  • When using a full body transmit radio frequency (RF) coil, do not scan patients with a specific absorption rate (SAR) level exceeding 2 W/kg. A scan above 2 W/kg may increase the risk of MRI-related heating.
  • When using head transmit RF coil, do not exceed head SAR of 3.2 W/Kg.
  • Do not place a local RF transmit coil directly over the implanted StimRouter Lead.

StimRouter External Components Restrictions:

  • All external components of the StimRouter System are contraindicated for the MRI environment. Therefore, the StimRouter Electrode, External Pulse Transmitter and Patient Programmer must be removed before the patient is allowed into the MRI environment.

To ensure patient safety, please review the complete guidelines carefully on the conditions of use, risks, warnings, and instructions on using MRI with the StimRouter Neuromodulation System. This page is designed only as a brief supplement to the complete guidelines. MR scans performed outside the guidelines may result in the MRI field interacting with implanted devices, potentially injuring the patient and damaging the implanted device.
