# Condition for Scanning
3. MRI System Settings
a. Only for Patients Implanted with WaveWriter Alpha
System and Avista MRI Leads:
Scanner operation at or below 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.
b. For Patients Implanted with WaveWriter Alpha System
and Leads listed in Table 1:
If Head Transmit/Receive Coil is used, scanner
operation at or below Normal Operating Mode limits
for RF and Gradient Exposure: Head SAR must be
≤ 3.2 W/kg.
If Full Body Transmit/Receive Coil or Extremity
Transmit/Receive Coil is used, then the scan sequence
throughout the scan must have B1+ rms less than or
equal to (≤) 3.2 µT.
• If B1+rms is not available, then the 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.
4. Patient must be positioned in supine or prone position during
the scan.

Supervision

Note: The patient should be in a psychological condition and mental state in which the patient is able to provide immediate
feedback of any problems during the examination.
ImageReady™ MRI Full Body Guidelines for WaveWriter Alpha™ and WaveWriter Alpha™ Prime Spinal Cord Stimulator Systems
Actions
Ensure MRI Scanner is operated at or below Normal
Operating Mode.
For Head Transmit/Receive Coil, ensure MRI Scanner
is operated at or below Normal Operating Mode.
For Full Body or Extremity Transmit/Receive Coil,
ensure MRI Scanner is operated at or below B1+ rms
of 3.2 μT.
If B1+rms is not available then ensure MRI scanner is
operated at or below Whole body and head SAR of 0.4
W/kg.
Continuously monitor the patient to ensure the patient
is in the correct position during scan.
