Magnetic Resonance Imaging (MRI) is one of the most advanced
diagnostic tools for today's physician. It allows
your physician to see inside your body without surgery
or the use of ionizing radiation. MRI uses a powerful
magnet, low intensity radio waves and computer technology
to create detailed images of the soft tissues, mussles,
nerves, and bones of the body.
How
MRI Scanners Work...
The main component
of the MRI system is a magnet. The magnet causes your body's
hydrogen atoms to align themselves in such a way as to recieve
radio signals from the magnets resonance system. When the
signal is turned off, the atoms re-align giving off energy as
they move. This energy becomes the data information that
is then read into a computer and translated into pictures.
Understanding Contrast Media...
Certain types of MRI exams require the use of a safe paramagnetic
agent (contrast media). The contrast media which is
given intraveneously during the exam, highlights the area
of concern. Because this agent is used in certain studies,
please tell your physician if you are pregnant, think you
are, or are breast feeding. Consult the MRI staff or
your physician if you have any questions about your eligibility.
The Actual Exam...
Your MRI exam is really quite simple. With the assistance of
the MRI Technologist, you will be positioned on a padded table. The
table will move slightly into the magnet opening and your exam
will begin. During your MRI, you won't feel anything.
The only thing you will notice is a knocking sound that occurs
as the images are taken. This is normal, and you will
be provided with hearing protection. Your Technologist
will conduct the study from an adjacent room. You will
be able to speak with the Technologist through an intercom
during the exam. The length of the exam is dependent
upon the study being done, anywhere from 25 to 60 minutes.
Once the exam is completed, you are free to go. That's
all there is to it!
Our board certified Radiologists will report the results of
your MRI examination directly to your doctor. |
