What is a CT?
A CT focuses a thin beam of x-rays in a specific part of your body, such as the head, chest, abdomen, or spine. The table moves through the x-ray field producing a cross sectional image of the body part.
During some CT scans, an IV injection of contrast material is needed to better evaluate vessels and organs.
Preparing For Your CT
Wear comfortable clothing with no metal. Jewelry and other accessories should be left at home if possible, or removed prior to the CT scan.
Let you technologist know if...
- you are or there is a possibility you are pregnant
- you are allergic to iodine, x-ray dye, or IVP dye
- you have had a CT scan before and experienced any discomfort from the injection
- you are diabetic

- For some exams, in addition to an IV injection, you make be asked to drink a contrast solution.
- You will be asked to lie on the table that slides into a ring shaped machine. The part of your body being scanned will be placed in the middle of the ring.
