CT is a painless, non-invasive test that will not hurt at all.
Your exam might require that you be given a contrast agent, however. A contrast agent is a liquid substance that makes certain tissues stand out more clearly against their surroundings, enabling the finest details to show up on the X-ray and thus improving diagnostic accuracy. You may be given the contrast agent intravenously or orally. In all cases the contrast agent will leave your body naturally within a few hours. (If your exam does require a contrast agent, be sure to tell the technologist if you have any allergies, especially to iodine or shellfish, or a history of kidney disease.)
Once the technologist has positioned you appropriately on the table, you will then be asked to lie perfectly still. You may also be asked to hold your breath for a few seconds during the exam. Any movement might require the exam to be repeated.
The CT scans take just a few minutes, and you should receive results within a day.
