 CT (CAT Scans)

“CT” or “CAT” scan are common terms used to describe a radiographic test known as “computerized tomography”. The CT scanner is a circular-shaped machine that takes pictures of cross-sections of the body, referred to as “slices”.

A  CT can see inside the brain and other parts of the body areas that

cannot be seen with x-rays. This makes it possible to diagnose certain diseases earlier and more accurately.

Preparing for a CT exam

Most CT scans require contrast. CT scans of the head and chest require you to have nothing to eat or drink for 2 hours prior to the test. CT scans of the abdomen and pelvis require you to drink barium. One bottle is taken the night before the exam, another the day of the exam. Your physician will notify you of the specific instruction for your exam.

Exam Day:

• Please arrive 10-15 minutes early to complete the registration process. 
• CT scans of the head (brain) require removal of jewelry, hairpins, etc.
• Scans of the chest, abdomen and pelvis require changing into a patient gown.  

You may be asked to sign a consent form if I.V. contrast (x-ray dye) is to be used. I.V. contrast is injected into the bloodstream through a small needle in the arm or hand. It is used to “highlight” the vessels and organs of the abdomen (which aid in diagnosis). You may also have blood drawn in the laboratory prior to an exam that uses I.V. contrast to check for adequate kidney function.
