MRI Safety

• Definition
• Magnetic Resonance Imaging
• What does it do?
• It uses the magnetic field to project images onto
  a TV screen and can give cross-sections of the
  body to locate irregularities or disease.

MRI Safety Precautions

• MRI magnet room is extremely powerful. The
  magnetic will bring all magnetic metal toward it,
  sometimes at high speed. (On August 2, 2001 a
  child was killed because a care giver brought in
  an oxygen tank on the stretcher, it flew into the
  center of the magnet where the child was lying)
• Leave any metal object outside of the building.
• Check with MRI Operator if access is needed in
  the room with the magnet.

Magnet Quenching

• The donut shaped, closed magnet is actually
  surrounded by a container that contains liquid
  helium. This can be released by the technician
  if something or someone is sucked up into the
  magnet.
• Quenching poses a unique risk in that it will
  replace the oxygen with inert helium. This will
  suffocate anyone in the room. If the alarm goes
  off leave the room immediately and do not breathe
  until outside.

General MRI Safety

• Do not go into the Magnet Room alone
• Check with the manager if the room needs to be
  entered at night or off duty times.
• Respect the potential for injury. It is
  extremely powerful!!
