What
is MRI?
Magnetic Resonance Imaging,
or MRI as it is referred to, is a patient examination
utilizing a magnetic field and radio waves to produce a
highly accurate view of the inside of any portion of your
body. It is a painless and extremely safe procedure
because no radiation is used.
Aided by a computer, MRI is
able to produce an image of bone and soft tissue from many
different body angles or planes. This enables
Associated
Radiologists, PA's physicians to quickly and precisely
diagnose a wide variety of conditions.
What
is Open MRI?
An Open MRI produces the same
results as a normal MRI, but the machine used in the
examination is open on all sides.
Associated Radiologists,
PA uses an Open MRI Imaging
System by
Hitachi. This machine uses a
specially designed patient gantry which is much more spacious
and comfortable. No longer do you have to squeeze inside
a narrow tunnel to get the high quality MRI pictures
your doctor needs.

How do
I prepare for the exam?Go on with
your normal activities, eat light meals, and take any
prescribed medications as usual. If possible, avoid
wearing cloths that have metal buckles, buttons, or
zippers. Do not use hair spray or eye makeup and please
bring your insurance information with you along with any
previous X-rays or imaging studies of the area to be
examined.
What
will the exam be like?You will be
met by your MRI technologist who will be performing your
examination. This technologist has completed a rigorous
course of education and training, and works under close
supervision of the radiologist to assure the most accurate
results from your examinations.
The technologist will
position and gently secure you on the imaging table.
It's important that you be secured, because even the
slightest movement during the exam can blur the image and
result in the need for repeated scans.
When you and your
technologist are ready the examination table will be moved
into the MRI unit, which is an air-conditioned
chamber. Your technologist will have you in full view at
all times and be in constant communication via two-way
microphones. You won't feel a thing, but you may hear the
hum of the equipment as the images are being produced.
You may be given a contrast
medium to highlight a particular part of your body. The
contrast medium outlines less dense, hollow vessels and
organs for visualizations. This medium is eliminated
within a few hours or a day or two depending on the area
under examination and the type of contrast medium
utilized.
How
long will the exam take?The exam usually
takes from 30 to 60 minutes. Time may vary significantly,
depending on the nature of the study and other factors.
What
do I do after the exam?You can resume
all of your normal activities.
When
will I know the results?
A radiologist will study your
films and report the findings to your doctor within 24
hours. Your doctor will discuss the MRI results with you.
