Multiple detector computed tomography or (MDCT) scanning is
a rapid, painless diagnostic procedure that combines the use of computers and
x-rays. A MDCT scan allows the radiologist to see the location, nature and extent
of many different diseases
or abnormalities.
Multiple images are acquired in a sequence by a rotating x-ray tube. All you
need to do is lie still on a table for approximately 5 to 15 minutes, depending
on the area of concern being covered. The table top will move you through a
gantry (shaped like a big donut) which houses the x-ray tube and a multiple
set of detectors. Images are acquired by the detectors that pick up the x-ray
that passes through your body. The images are then sent to the computer which
reconstructs the images onto the screen for the technologist to view. The technologist
will then review the quality of the images, once satisfied with the content
of the exam you will be free to leave. The technologist will then process this
information to create an examination that the radiologist can then review and
interpret.
Some MDCT studies require an oral contrast agent to enhance the images that
are taken of your body. You will receive special instructions if your exam requires
you to consume an oral contrast agent (Redicat) in advance. Other studies may
use an I.V. contrast agent (Visipaque or Omnipaque) to enhance the images. You
will be instructed to arrive 20 to 30 minutes prior to your scan time to be
properly instructed for your exam. At this time the technologist will answer
any questions regarding the procedure.
The following tests do not require any preparation:
>>Chest only
>>Extremities
>>Head without contrast
>>Sinus
>>Spine: Cervical, Thoracic, Lumbar
