What is MRI?
MRI uses a large magnet, radio frequency signals that are transmitted
through the body, and sophisticated computers to produce a series of
magnetically generated images. These images can be used to diagnose many
conditions or monitor the progress of treatment for diseases. Because MRI
can see through bone and clearly define soft tissue, it can be used to
make a diagnosis in some areas that x-rays can not.
The exam is performed by a highly skilled technologist and studied by a
radiologist with specialized training in the field of MRI, who will then
provide a written report of the findings to your physician. If you have
any questions about the MRI, please call 798-5023.
What To Expect
Report to the Admitting/Registration in the main lobby to register on the
day of the exam. You must remove any metallic objects such as body
piercings, hairpins, glasses, jewelry and non-permanent dentures, etc.
Rings need not be removed. All personal items and clothing removed will be
secured in a locker.
As the scan begins, the table will slide into the circle containing the
magnet. The part of the body being imaged is in the middle of the scanner.
You will not feel anything, but there will be jackhammer-like noises as
the magnet and radio waves send signals to a computer. During the exam,
you must remain completely still. During the scan, you may be injected
with a contrast medium which will enhance the part of the body being
studied and provide the radiologist with some additional information.
Scanning time is 30-45 minutes on the average, however, total time for
an MRI can vary from one to two hours in specific situations. When the
scan is completed, the images are reviewed for quality and provided they
are acceptable, you will be discharged.
CAUTION
People with cardiac pacemakers, people with metal slivers in their eyes,
or people who have specific implanted devices can not be scanned. Any
woman who is pregnant, or thinks she might be, should advise her doctor
before proceeding with this exam.
