Introduction
About This Manual
This manual is intended for use by physicians, and other healthcare professionals (HCPs) responsible for managing
patients with a Boston Scientic Deep Brain Stimulation (DBS) System, as well as radiologists and other HCPs involved
in performing magnetic resonance imaging (MRI) scans on such patients.
The manual provides guidelines to determine whether and how to conduct a MRI scan on a patient implanted with any
component of the Boston Scientic DBS System.
Caution: Read this manual in its entirety before performing a MRI scan on a patient implanted with any component of
the Boston Scientic DBS System.
Caution: MR conditional scan may be safely performed when implanted with only the Boston Scientic DBS
components listed in this manual and when the patient is exposed to the MRI environment under specic
conditions dened in this manual. Other congurations have not been evaluated.
Obtain the Latest MRI Guidelines
Always obtain the latest MRI guidelines. See to the “Technical Support” section of this manual, or go to
www.bostonscientic.com/manuals for the latest version of this manual.
Patient Materials for an MRI
Advise the patient to bring the following to all MRI appointments:
• Remote Control
• Charger (if implanted with a rechargeable device)
• Their most up‑to‑date Patient ID Card
The patient’s Remote Control should be used to place the DBS System into MRI Mode prior to a scan; see the “Enabling
MRI Mode” section of this manual for more information. In order to enter MRI Mode, rechargeable Stimulators must
be fully charged. MRI personnel can use the Patient ID Card to identify Boston Scientic as the manufacturer of the
patient’s DBS System and to conrm the model number of the implanted system components.
Note: The Charger and Remote Control are MR Unsafe and must not be brought into the MRI scanner room.
