MAGNETIC
RESONANCE IMAGING (MRI)
What is Magnetic Resonance
Imaging (MRI)?
Magnetic Resonance Imaging (MRI or MR) is one of the
safest, most comfortable imaging techniques available.
It combines a powerful magnet with an advanced computer
system and radio waves to produce accurate and detailed
cross-sectional pictures of the human body. Unlike other
techniques, MRI uses no x-rays or radiation.
Common Uses
MRI produces highly detailed pictures of soft-tissue
structures near and around bones, blood vessels, organs
and the brain. It is widely used to examine such diverse
things as:
• Spinal and joint problems
• Small tears and injuries to tendons and ligaments
• Sports injuries
• Work-related disorders from repeated strain
• Arthritis
• Stroke
• Reproductive organs
• Organs of the chest and abdomen
Exam Preparations
You may follow your normal diet and take any medications
in your usual fashion.
Because MRI technology uses a very strong magnetic field,
please notify the center if you have a pacemaker, aneurysm
clips or any other metal implant and if you have ever
worked with metal, been exposed to metal shavings, worked
as a grinder or think you might be pregnant.
You should wear loose, comfortable clothing free of
metal zippers or buttons like sweats. Bras with metal
clasps or under wires cannot be worn in the scanner.
If you prefer, you may change into a gown.
A sound system is available if you'd like to bring a
CD to listen to during the exam.
A small percentage of people who have difficulty with
small confined spaces may experience some anxiety during
the procedure. If you feel you may be one of them, please
have a friend or relative drive you to your exam. This
will allow the center to administer a sedative or relaxant
if necessary.
During the Exam
When you arrive, you may need to change into a gown
or pajamas and will be asked to remove all metal objects
before going into the scanning room. You may wish to
leave your jewelry and valuables at home, or we have
secured lockers where you can store these items. The
technologist will help position you on a padded table
in front of the magnet. Depending on the type of exam
you are having, you will then enter the scanner head
first or feet first. The technologist will begin by
moving the table into the magnet. During the exam, the
technologist will be inside the control room watching
you at all times. An intercom system allows you to talk
freely with the technologist. As the exam starts, you
may hear a variety of thumping noises, similar to light
hammering. Some people find this noise relaxing, but
we also have earplugs and stereo headsets available
for your comfort. While the scanner is working, you
may feel a slight vibration; but other than this vibration,
you should not experience any other sensations. The
procedure takes between 30 and 60 minutes.
After the Exam
MRI has no side effects or ill results. You are free
to resume normal activity following your exam. However,
if a sedative was administered, you must refrain from
driving or operating machinery for the remainder of
the day.
Your tests will be reviewed promptly by one of our board
certified radiologist. Our goal is to provide your physician
with a report within 24 hours of the examination.
