MRI SAFETY FOR NON-MRI PERSONNEL

WHAT IS MRI? exam, a patient is exposed to three different forms of 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.

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.
