ImageReady™ MRI Guidelines for Boston Scientific Deep Brain Stimulation Systems
Table 13. Full System Conditions and Methods to Determine Eligibility
Condition for Scanning
Scan sequences must not exceed RF exposure limits
(B1+rms or SAR).
Cumulative active scan time (with RF On) should be limited
to 30 minutes or less per imaging session. If 30 minutes of
active scan time is reached allow 60 minutes of non‑active time
before proceeding.
Patient must be positioned in supine or prone position during
the scan.
Patient should be in a psychological condition and mental state
to be able to provide immediate feedback of any problems
during the examination.

Suggested Methods to Determine Eligibility
□
Check anatomical location of the isocenter.
□
Determine implanted components by checking Patient ID Card or patient
record.
Note: RF exposure limits and compatible components differ for
Full System scans when patients are implanted with the
Vercise Gevia Stimulator. When the Vercise Gevia Stimulator
is implanted, only configurations using DB‑2201 or DB‑2202
Lead(s) with NM‑3138‑55 Lead Extension are scan‑eligible.
□
Determine the coil type:
□
Head transmit/receive (RF quadrature only)
OR
□
Body transmit/receive coil (RF quadrature only)
□
Ensure MRI Scanner is operated at or below (≤) appropriate RF
exposure limits (B1+rms or SAR) based on isocenter, implanted
components, and coil type (see Table 8, Table 9, Table 10, and
Table 11).
□
Check the active scan time on the MRI scanner.
□
Continuously monitor the patient to ensure the patient is in the correct
position during scan.
□
Maintain visual and audio monitoring of the patient throughout the MRI
scan. Verify that the patient is feeling normal and is responsive during
and between each MRI scan. Discontinue the MRI immediately if the
patient becomes unresponsive or experiences any adverse events
listed under "Potential Interactions with MRI Environment" in the "Safety
Information" section of this manual.
