20 English MRI guidelines for Medtronic neurostimulation systems for chronic pain
Transmit/receive head coil only.
Important:
▪
The RF transmit-receive head coil must not cover any
implanted system component. Implanted system
components may be located per approved labeling and
may be as close as 0 cm to the lower (caudad) edge of the
head coil, but no part shall be inside the head coil.
▪
Ensure that the RF transmit body coil is not used.
▪
If you are unsure if your MRI system has RF transmit/
receive head coil capability, consult the MRI
manufacturer.

Warnings:
▪
An MRI examination of the head only (no other part of the
body) can be conducted safely using an RF transmit/
receive head coil when all instructions in this head-only
eligible section are followed.
▪
Do not place any part of the RF transmit/receive head coil
over any implanted neurostimulation system component.
If the head coil extends over any part of the patient's
neurostimulation system, higher than normal heating may
occur at the location of the implanted lead electrodes.
In addition, if the patient's neurostimulation system has a
broken lead wire and the head coil extends over any part of
the patient's neurostimulation system, higher than normal
heating may occur at the break or lead electrodes.
Excessive heating can cause tissue damage or serious
patient injury.
1.5-T horizontal closed bore with maximum spatial gradient of
19 T/m (1900 gauss/cm).
w
Warning: Only use 1.5-T horizontal closed bore MRI
systems. Other MRI systems (such as 0.6-T or 3.0-T, and
open bore machines) have not been tested and could cause
device damage and excessive heating, which can result in
tissue damage or serious patient injury.
No restrictions.
