MR Conditions of Use
4. MRI system settings:
Head Transmit/
Receive Coil
Full Body Transmit/
Receive Coil or
Extremity Transmit/
Receive Coil
Warning: Apply the required B1+rms (or SAR) limit in the Normal Operating Mode. Do not conduct MRI
scans in the First Level and Second Level Controlled Operating Modes as it may increase the risk of unin-
tended stimulation and excessive heating.
5. Monitoring:
• The patient must be under continuous audio/visual monitoring during the MRI.
6. Exposure Time:
• 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.

92395577-02 8 of 797
Full System with All Leads listed in Table 1
Normal Operating Mode limits for RF and Gradient Exposure:
Head SAR must be (≤) 3.2 W/kg
Note: Whole Body SAR is not applicable for Head Transmit/Receive scanning.
B1+rms ≤ 3.2 uT
If B1+rms is not available, then scan sequence
must have Whole body and Head SAR less
than or equal to (≤) 0.4 W/kg
Note: Using the SAR value may result in a
more restrictive MRI scan.
Full System with SC-2408 Avista Leads only
Normal Operating Mode limits for RF
and gradient exposure:
Whole Body SAR must be (≤) 2.0 W/kg
Head SAR must be (≤) 3.2 W/kg
