Radiology -CT Scan
Frequently Asked Questions:
If you or someone you care about needs a diagnostic scan, you might have questions about what to expect. Here are answers to commonly asked questions. Ask your doctor or CT technologist for more information about this quick and pain-free diagnostic procedure.
What is a CT?
CT stands for computed tomography (sometimes referred to as a CAT scan) and is a fast, painless tool that doctors use to see inside the body. A CT scanner combines X-rays with computer technology to create detailed images of your internal structures and organs.
Will I feel claustrophobic?
Our state-of-the-art system is designed to enhance patient comfort and has a more open design than many traditional CT scanners. This allows patients to see outside of the machine during examinations and helps to reduce claustrophobic effects.
Are there any people who shouldn't get CTs?
If you are pregnant, think you might be pregnant, or have allergies to fish or iodine, you should inform your doctor and CT technologist prior to your exam.
Will the CT scan hurt?
No. CT is a painless, non-invasive test. Your exam might require you to take a contrast agent that will make your blood vessels and tissues more visible. You may also be asked to hold your breath for a few seconds during the exam.
How long will my CT exam take?
It depends on which study your doctor has ordered. Most exams are quick and last just a few minutes. You may be asked to arrive 15 or 30 minutes prior to your exam time.
Do I have to do anything special to prepare for my CT scan?
How you prepare for your CT scan depends on what part of the body is being examined. You may be asked not to eat or drink anything before your exam.
What is a contrast agent?
A contrast agent is a liquid substance that makes tissues stand out more clearly against their surroundings, enabling details to show up on the X-ray. You may be given the contrast agent intravenously or orally. It will leave your body naturally within a few hours.
Will I be alone during the CT exam?
During your CT exam, you will be in contact with a technologist. Even when he or she is not in the CT room you will be able to communicate via intercom. The technologist will inform you when an exam is about to start, and when it is finished. Family members and/or friends are typically not permitted to stay with you.
