What is an MRI?
MRI (Magnetic Resonance Imaging) allows doctors to see inside the human
body using a powerful magnet, radio waves, and a computer system to
produce three-dimensional pictures of various areas of the body. Using no
radiation, this computerized examination is safe and painless.
Why do I need an
MRI?
An MRI exam can be used to view your body's internal organs, including
soft tissue like the brain and muscles. Physicians can get as much
information from looking at the MRI film as from looking at the actual
tissue. MRI can, in some cases, eliminate the need for invasive studies
and surgery.
How do I prepare?
Very little preparation is required. You may eat, drink, and take your
medications as normal. You will be asked to remove all metallic items,
such as watches, jewelry, and hearing aids. Because of the potential
harmful effects associated with some metallic objects in a magnetic field,
you should let your technologist know of any prior brain, ear, eye, or
other surgeries or if you have any of the following:
- Pacemaker
- Metal Implants
- Aneurysm Clips
- Surgical Staples
- Neuro-stimulator
(Tens-unit)
- Implanted Drug
Infusion Devices
- Foreign Metal
Objects in the Eye
- Shrapnel or
Bullet Wounds
- Permanent
Eyeliner
If you have ever
been a metal worker, you may be required to have special X-rays before the
scan to make sure there are no metal fragments in your eye(s). If you are
pregnant, be sure to notify your physician and the technologist.
During the exam?
You will be asked to complete a questionnaire regarding your medical
history. Some procedures are enhanced by using a contrast agent. You will
then be positioned on the exam table that will move into the
circular-shaped magnet. The procedure typically will last anywhere from 30
to 60 minutes, depending on the type of information required by your
physician. All that is required of you is to be as still as possible.
After the exam:
If sedation was necessary, you may need someone to take you home.
