CT Scan (CAT Scan) A CT scan is a special kind
of X-Ray imaging in which a thin x-ray beam rotates around the patient allowing
doctors to see highly detailed images. ADI's computer combines the images to
form highly detailed three-dimensional pictures of the body. This type of
imaging significantly helps the physician in determining a
diagnosis.

The most common CT scans
ordered will be of head, chest, abdomen, and pelvis. Sometimes multiple CT
scans are done at the same time, (i.e. the chest and abdomen). Most times, an
intravenous dye is given to help the doctors determine normal from abnormal
findings. The contrast is ionic, so if you are allergic to iodine or shellfish,
let your physician know.You will feel warm while the contrast is injected, but
it only lasts for a minute.
If your doctor wants to scan your abdomen,
you will have to drink a glass of oral contrast 1 hour prior and another glass
30 minutes prior to the scan. For CT scans with contrast, it is recommended
that you do not eat or drink 4 to 6 hours before the scan (except for the
contrast for the scan). A CT scan usually only takes 10 to 15 minutes once you
are prepped for it.
About The TestHow The Test Is
Performed
You will be asked to lie on a table that slides into the
center of the scanner.
How The Test Will Feel
The process
is painless. If contrast dye is to be administered, an IV will be placed in a
small vein of a hand or arm.
Why The Test Is Performed
CT
provides rapid, detailed images of the patient that can then be reconstructed
into three-dimensional images. Intravenous contrast improves evaluation of
vessels and improves detection of tumors.
What The Risks Are
CT scans and other x-rays are monitored and regulated to provide the
minimum amount of radiation exposure needed to produce the image. The risk
associated with any individual scan is small. |
