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.
