A "CT scan" (Computed Tomography scan), also known as a "CAT scan," (for "Computed Axial Tomography") is a diagnostic test that combines the use of X-rays with computer technology. A series of X-ray beams from many different angles are used to create cross-sectional images of the patient's body. These images are assembled in a computer into a three-dimensional picture that can display organs, bones, and soft tissue in great detail.

Abdominal Scan: You will be asked to arrive at least one hour before your scan, so that you will have time to prepare for the test. During this hour, you will be asked to drink a contrast liquid (diluted barium) which is opaque to X-Rays, and improves the visibility of the gastrointestinal tract.

The CT scanner consists of a large donut-shaped machine and an X-ray table. You will lie on the table and be slowly moved into the large opening as a series of X-Ray images are taken. During the examination you will be asked to lie very still and follow the instructions of the operator while the scan is being performed.   You may be given an injection of Intra-Venous dye (contrast) which improves the visibility of the blood vessels. After receiving the dye,  few people experience some nausea and a feeling of heat, although only for about a minute. There is a slight possibility of having an allergic reaction to the X-ray dye. The only way to know if you will have a reaction is from your previous history or by actually taking the dye. Your kidneys will filter the I.V. contrast out of your bloodstream within a few hours after the exam. The barium should pass through your gastrointestinal tract normally.

The abdominal CT scan examination takes between 15 minutes and one hour, and is painless. You should not worry about the amount of radiation you are taking, as the dose is low and is confined to a small area. Besides, if your doctor recommended a CT scan, it was because the diagnostic benefit of the X-rays outweigh the risk.

Do not eat solid food for three hours prior to the exam. You may drink clear liquids during this time. Routine medications may also be taken.

Special note:    If you have asthma, any known allergy to food or medications, or are pregnant, please inform the receptionist before your exam.
