MRI SAFETY
FOR NON-MRI PERSONNEL
WHAT IS MRI?
During an MRI
exam, a patient is
exposed to three
different forms of
electromagnetism
THREE FORMS OF
ELECTROMAGNETISM

STATIC

GRADIENT

RADIOFREQUENCY
MAGNETIC FIELD
The MRI
system is
always on and
danger is
always present.
MAGNETIC FIELD
 365
7
Days/Year
Days/Week
 24
Hours/day
MAGNETIC FIELD
There is a
magnetic field
present even
when no patient
is in the room
MRI SYSTEM SHUTDOWN!

Emergency
situations only!
 The shutdown
procedure can only
be performed by
trained
professionals!
 An improper
shutdown can
release harmful
gasses into the MRI
system room!
METAL OBJECTS
Metal objects can
become
dangerous and
deadly projectiles
within the
magnetic field!
THE MISSILE EFFECT

OCCURS WHEN A
FLYING METALLIC
PROJECTILE IS
DRAWN TO THE
CENTER OF THE
MAGNET.
THE MISSILE EFFECT
 CAN
LEAD TO
SUBSTANTIAL
COSTS IN
REPAIR AND
MRI DOWNTIME!
MRI ACCIDENTS
Problems that occur
mostly are related
to:

Bringing external
metallic objects into
the MRI system
room.
MRI ACCIDENTS
AND

Accidental exposure
of patients or
individuals with
certain implants,
such as, cardiac
pacemakers,
pumps, and
stimulators.
REQUIREMENTS
All persons are
required to
undergo
screening before
being permitted in
the MRI
environment.
SCREENING PROCESS
The screening process
consists of
questions regarding:

Implanted devices
 Prior surgeries
 Possibilities of any
metallic foreign
bodies
SCREENING PROCESS
Before entering the MRI
system room the
following items must be
removed:

Metallic personal
belongings
 Watches
 Pocket knives
 Nail clippers
 Jewelry
 Scissors
SCREENING PROCESS
Before entering the MRI
system room the
following items must be
removed because it can
be damaged:

Hearing aides
 Cell phones
 Watches
 Beepers
MRI TIPS TO REMEMBER

The magnetic field
of the MRI system
is always on, and
dangers exist,
even when a
patient is not being
imaged.
MRI TIPS TO REMEMBER

If you enter the
room where the
MRI system is
located, you will be
exposed to the
powerful magnetic
field.
MRI TIPS TO REMEMBER

Remove ALL
metallic
belongings before
entering the MRI
system room.
MRI TIPS TO REMEMBER

If you have any
questions or
concerns, discuss
with the MRI
technologist or
radiologist.
