MRI SAFETY
FOR NON-MRI PERSONNEL
![Page 2: MRI SAFETY FOR NON-MRI PERSONNEL. WHAT IS MRI? During an MRI exam, a patient is exposed to three different forms of electromagnetism.](https://reader036.fdocuments.net/reader036/viewer/2022071806/56649d845503460f94a6afe2/html5/thumbnails/2.jpg)
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 Days/Year
7 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.
![Page 10: MRI SAFETY FOR NON-MRI PERSONNEL. WHAT IS MRI? During an MRI exam, a patient is exposed to three different forms of electromagnetism.](https://reader036.fdocuments.net/reader036/viewer/2022071806/56649d845503460f94a6afe2/html5/thumbnails/10.jpg)
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 ACCIDENTSAND
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.
![Page 14: MRI SAFETY FOR NON-MRI PERSONNEL. WHAT IS MRI? During an MRI exam, a patient is exposed to three different forms of electromagnetism.](https://reader036.fdocuments.net/reader036/viewer/2022071806/56649d845503460f94a6afe2/html5/thumbnails/14.jpg)
SCREENING PROCESSThe screening process
consists of questions regarding:
Implanted devices Prior surgeries Possibilities of any
metallic foreign bodies
![Page 15: MRI SAFETY FOR NON-MRI PERSONNEL. WHAT IS MRI? During an MRI exam, a patient is exposed to three different forms of electromagnetism.](https://reader036.fdocuments.net/reader036/viewer/2022071806/56649d845503460f94a6afe2/html5/thumbnails/15.jpg)
SCREENING PROCESSBefore entering the MRI system room the following items must be removed:
Metallic personal belongings
Watches Pocket knives Nail clippers Jewelry Scissors
![Page 16: MRI SAFETY FOR NON-MRI PERSONNEL. WHAT IS MRI? During an MRI exam, a patient is exposed to three different forms of electromagnetism.](https://reader036.fdocuments.net/reader036/viewer/2022071806/56649d845503460f94a6afe2/html5/thumbnails/16.jpg)
SCREENING PROCESSBefore 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.
![Page 18: MRI SAFETY FOR NON-MRI PERSONNEL. WHAT IS MRI? During an MRI exam, a patient is exposed to three different forms of electromagnetism.](https://reader036.fdocuments.net/reader036/viewer/2022071806/56649d845503460f94a6afe2/html5/thumbnails/18.jpg)
MRI TIPS TO REMEMBER
If you enter the
room where the
MRI system is
located, you will be
exposed to the
powerful magnetic
field.
![Page 19: MRI SAFETY FOR NON-MRI PERSONNEL. WHAT IS MRI? During an MRI exam, a patient is exposed to three different forms of electromagnetism.](https://reader036.fdocuments.net/reader036/viewer/2022071806/56649d845503460f94a6afe2/html5/thumbnails/19.jpg)
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.
