CT Scan (Computed Axial Tomography)
A CT (or CAT) scan is a method of body imaging in which thin x-ray beams create cross-sectional images of a particular body organ.
Preparation
You may be asked to fast and drink a contrast dye several hours and immediately prior to the scan. Our staff will discuss this process with you and provide you with the contrast when your test is scheduled.
You may also receive IV contrast dye just prior to the testing. Sometimes this is associated with a slight burning sensation within the injected arm, a metallic taste in the mouth and a warm flushing of the body. These sensations are normal and usually resolve within a few seconds. Most IV contrast dye is iodine based and a person allergic to iodine may experience more intense reactions. Please let us know if you are allergic to iodine or seafood as we may opt not to use IV contrast and/or premedicate you prior to testing.
There is a consent form for this procedure.
Procedure
During the test, you will be asked to lie still on a narrow table that slides into a donut-shaped scanner. Sometimes this occurs in small intervals and other times in one continuous motion. You may also be asked to hold your breath during portions of the scan.
A CT scan takes only a few minutes to perform.
