Magnetic
Resonance Imaging (MRI) uses a magnetic field ad radio waves instead
of X-ray to display many parts of the body, especially the brain,
spine and joints.
What
is an Open MRI?
Our open MRI has clear, unobstructed space on three sides, so
you can see and talk to our staff during the exam. That means
a more pleasant experience for you.
What
is the exam like?
The exam usually takes 30 to 60 minutes. It consists of several
image exposures lasting 10 to 15 minutes each. You'll be asked
to remove your make-up, eye glasses, watch, jewelry, credit cards,
dentures, hearing aids, and any other metallic objects you are
carrying. Then, the technologist will help you lie down on a cushioned
table. A device called a "Coil" will be placed over
or under you. It helps the MRI system create a clear picture of
your body. When you are comfortably positioned, the table will
move under the magnet. The technologist will then step into the
control area, while staying in constant contact with you both
visually and through an intercom.

As
the exam proceeds, you will hear a muffled thumping
sound for several minutes at a time. Other than the sound, the
MRI creates a no bodily sensation. Relax and try to lie as still
as possible. Any movement during this time will blur the picture.
When an exam is finished, the technologist will help you off the
table.
Do
I need to prepare for the exam?
No special preparation is needed. Eat normally and take medication
as usual, unless your doctor has given you other instructions.
You may find it easier to relax if you avoid drinking coffee or
other caffeinated beverages before the exam.
Is
there any risk?
Magnetic
Resonance Imaging is very safe. There are no health risks associated
with the magnetic field or the radio waves used by the machine.
However,
some special circumstances limit the use of a magnetic field,
so it is important for you to tell us if any of the following
apply to you or someone accompanying you into the exam room:
-
cardiac pacemaker or artificial heart valve
- metal plat, pin or other metallic implant
- intrauterine device, such as Copper-7 IUD
- insulin pump or other infusion pump
- aneurysm clips
- previous gun wound
- inner ear implant
- ever been a metal worker (had metal in eye)
- permanent (tatoo) eye-liner
Any
metallic substance on your person can affect the quality of the
diagnostic images. It can also case discomfort or injury to you
when placed in the magnetic field, and may exclude you from the
exam. Also, be sure to tell us if you are pregnant.
Will
I need an injection?
In most cases an MRI exam does not require any injections. In
some situations, however, a substance known as a contast agent
may be needed to enhance the ability of the MRI to see into your
body. All contrast agents are cleared by the FDA and are considered
safe.
