HEALTH CONCERNS
Caution: Sound Volume.
Do not use the audio headset on patients at high volume. It is advised against continuous loud and extended audio
play. If your patients experience ringing in their ears, reduce the audio volume or discontinue use the system use
until the patient feels comfortable.
MRI ENVIRONMENT HAZARDS
Installation of materials inside the MRI suite must be done with extreme caution and only by authorized personnel.
Care must be taken to keep ferromagnetic materials such as tools, filter plates, screws, etc. at least three meters
(approximately 1 feet) away from the energized magnet. Absolutely no work should be done near the filter panel
when a scan is in progress.
All cabling inside the MRI environment should either be connected or terminated properly. Failure to do so may
result in skin burns related to RF energy. All cables should be run straight and never looped, as this may also
cause serious skin burns inside the MRI room.
In addition, no persons with ferromagnetic prosthetic devices such as pacemakers or joint replacements should
enter the MRI suite at any time. Extremely high magnetic forces have the potential to dislodge ferrous items at
high velocities that can result in serious injury or death.
