Using MRI with an Implanted StimRouter® System
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.
Warnings, Precautions and Restrictions
1.5 Tesla and 3 Tesla MRI Warning and Precautions
If the entire StimRouter lead is at least 50 cm away from the center of the bore of the MR system and
the center of the transmit-RF body coil, the reported, whole-body-averaged (WBA) specific absorption
rate (SAR) must not exceed 2 W/kg at 1.5 T/64 MHz or a whole-body-averaged SAR of 2 W/kg at 3
T/128 MHz in the normal operating mode of operation for the MR system.
Limit B1+rms and SAR to values shown in Table 3.1 of the StimRouter MRI Guidelines if the entire StimRouter is not at least 50 cm from the center of the MRI bore.

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.
