What exactly is MRI ?
MRI stands for Magnetic Resonance Imaging.
Which is a powerful, dynamic way for doctors to see inside our
bodies to diagnose and identify certain problems and diseases.
An MRI is not an x-ray but a combination of magnetic fields, radio waves
and a computer that all work together to create two or even three dimensional
images of exactly whats happening within us.
Youll discover that MRI testing is painless and much quicker than
you think. In fact, youll probably be very comfortable as you lie
back on the padded table. You may even be able to listen to your favorite
music as youre scanned.
But keep in mind that an MRI isnt for everyone. So be sure to inform
your physician if you have: a pacemaker, aneurysm clips in the brain,
a shunt with telesensor, inner ear implants, metal fragments in one or
both eyes, implanted spinal cord stimulators, or if youre pregnant,
breast feeding or have anemia or any disease affecting red blood cells.
Many of your questions about MRI are answered here. But should you have
any other questions or concerns, please feel free to consult your doctor.
Q&A about your MRI.
WHY ARE MRI SCANS IMPORTANT?
MRI scans allow doctors to see images of your internal organs and structures
in great detail from many angles. This gives them information more quickly,
and in many cases more economically, than past tests and exploratory
surgeries.
IS AN MRI SCAN LIKE AN X-RAY?
No. An MRI scan uses a powerful magnet in conjunction with radio frequency
waves to generate images of your internal organs and structures without
radiation.
HOW LONG WILL THE EXAM TAKE?
That will depend on what is being studied, but a typical exam lasts between
20 and 60 minutes. You should allow extra time in case the exam lasts
longer than expected.
DOES THE MACHINE MAKE A LOT OF NOISE?
The magnet makes a slight rapping sound as images are being taken. In
between scans the machine is quiet. In some locations headphones might
be available to you, but their use will not prevent you from hearing
the technologist if he or she speaks to you during the exam.
DO I HAVE TO HOLD STILL THE WHOLE TIME?
It is important for image clarity and the best scan results to hold still
during the exam. The technologists will instruct you as to when you may
move between scans. Keep in mind a routine exam may take at least 20
minutes.
WILL I BE ALONE?
You will be in contact with a technologist at all times. Even when he
or she is not in the MRI room, you will be able to talk to him or her
by intercom. In some cases a family member is welcome to stay in the
room with you during your scan.
r e l a x:
An MRI will help doctors learn what they
really need to know about you.
Magnetic resonance is one of the most useful tools physicians have to
make an accurate diagnosis and select an appropriate treatment for their
patients. Because these images are computer generated, they can be instantly
sent electronically to off-site specialists and consultants. Thanks to
advanced design features, your MRI should prove perfectly comfortable.
In fact, you may even find the experience relaxing.

About the ONI High Field Dedicated Extremity MRI System
Your doctor has prescribed an MRI to help determine the nature and extent of your injury. Because it involves only part
of your arm or leg, you have been referred for study on the world’s first and only high field, dedicated extremity MRI system.
What you can expect:
A comfortable, non-threatening, non-claustrophobic MRI device that creates scans with extremely high quality images. A truly open MRI
system. The scan is performed with you sitting in a comfortable chair. The only part of your body to go into the magnet is the part being scanned.
Is there any preparation?
No, there is no fasting or special preparation necessary for an MRI.
How should I dress?
Since the MRI uses a very strong magnet, you should not wear clothes that have metal snaps, buttons, zippers or other fastenings. Any coins, keys,
watch, jewelry, credit cards, cell phone, pager or other item that is magnetic or may contain metal should be left with the technologist for safekeeping.
Do I go into a tube?
No, you sit in a comfortable chair. Only the body part being examined needs to go into the magnet. Many patients find the procedure so
comfortable that they fall asleep during the scan.
What happens during the scan?
During the scan you will hear a humming or vibrating sound. When you hear this sound it is important to keep still. Motion during the
scan affects the quality of the image. If you move during the scan the technologist may have to repeat parts of it.
What happens after the scan?
You can leave immediately after the scan is completed. The images from the procedure will be reviewed by a Radiologist.
