Obtain the latest MRI guidelines labeling

Always obtain the latest MRI guidelines. Refer to the contact information at the back of this
manual, or go to www.medtronic.com/mri.
Copies of these MRI guidelines may not be the most up-to-date version if not received
directly from the website or in another manner from Medtronic the same day of the patient's
MRI appointment.

Clinician programmer and patient control device

For Medtronic neurostimulation systems with SureScan MRI Technology, external control
devices (ie, a clinician programmer or a patient control device) are used to determine MRI
scan-type eligibility and are used to place the neurostimulation system in MRI conditionally
safe (MRI-CS) mode (also referred to as "MRI mode"), which turns stimulation off. Inform
the patient with a neurostimulation system that stimulation needs to be turned off prior to
the MRI scan.
If the patient brought a patient control device to the MRI appointment, go to "START HERE
– Eligibility identification" on page 8 and use the identification checklist in that section.
If the clinician programmer or a patient control device cannot communicate with the
implanted neurostimulation system or if the neurostimulator has reached EOS (end of
service), then MRI conditional safety cannot be confirmed via the external control devices.
Researching the implanted neurostimulation system configuration from the patient's
medical records is required. Unless the implanted system configuration is known and it is
determined to be safe to perform an MRI under specific conditions, an MRI scan should not
be conducted.
For operation of the clinician programmer, refer to the appropriate clinician programmer
software manual for those instructions.

Types of electromagnetic fields generated by MRI systems

An MRI system produces 3 types of electromagnetic fields that may interact with implanted
device systems. All 3 of these fields are necessary to produce an MRI image. The 3 fields
are defined as follows:
Static magnetic field – This is a steady state non-varying magnetic field that is always
present around an MRI machine, even when no scan is underway.
Gradient magnetic fields – These low-frequency pulsed magnetic fields are present only
during a scan. MRI equipment uses 3 orthogonal gradient magnetic fields to construct the
3-dimensional image.
RF field – This is a pulsed radio-frequency (RF) field that is present only during a scan.
The RF field can be produced by a variety of transmission RF coils, such as a whole body
transmit coil (that is built into the scanner) or an extremity coil (for example, a transmit/
receive head coil).
