Enter the correct patient weight into the MRI
console to ensure that the head SAR is estimated
correctly.
Verify that all proposed MRI scan parameters
comply with the MRI scanning conditions in this
head-only eligible section. If these conditions cannot
be met, do not proceed with the MRI scan.
Image artifacts and distortion resulting from the
presence of the device, the leads, and any other
DBS system components within the field of view
must be considered when selecting the field of view
and imaging parameters.
Table 10. Head-only eligible – During the MRI scan
No restrictions.
The patient may feel heating at the neurostimulator
site during the MRI scan. If the heating causes
patient discomfort, stop the MRI scan immediately.
During the MRI scan, the patient may feel tugging
and/or vibration of the neurostimulator. If the
tugging or vibration causes the patient considerable
discomfort, stop the MRI scan.
Table 11. Head-only eligible – Post MRI scan
Verify that the patient has not experienced adverse
effects as a result of the MRI scan.
Contact Medtronic to report any adverse effects.
