Does a CT scan hurt?
No, CT imaging itself is painless, although some scans require that patients receive an IV injection prior to or during the exam.

Do I have to hold still during the whole exam?
You will need to hold as still as possible; patient motion can compromise image quality. We may ask you to hold your breath at certain times to reduce breathing motion.

Will I fit comfortably in the scanner?
Most people fit comfortably inside the scanner. However, for some exams we may need you to place your arms above your head. Some people who have trouble doing this may experience some discomfort, but it is usually for only a minute or two.

Will I be able to keep my head outside of the CT machine? 
Yes, youll be able to keep your head outside of the scanner, unless we are scanning your head or neck. However, most people do not have a problem with this since the scanner is very shallow --  like a big donut.

Is it okay to have a CT during pregnancy?
It is important to notify your physician or the technologist before the scan if it is possible that you might be pregnant. The physician will determine whether another test, such as an ultrasound, should be performed instead.

Do I need a referral (prescription) to receive a CT scan?
Yes. Your physician must give you a referral in order to undergo a CT scan.

Do I need a contrast injection before my CT exam?
IV contrast is only used when the radiologist determines that it is necessary. Iodine contrast enhances images of specific organs, blood vessels, and tissues to better show the presence of injury or disease. Please inform the technologist if you are, or think you might be, allergic to iodine or IV contrast.

Why are both oral and IV contrast used in CT?
Oral contrast is a very dilute barium solution that patients drink 60-90 minutes prior to their scans. It enhances images of the stomach and intestines. IV contrast enhances scans of the blood vessels and organs. One or both forms of contrast may be used, depending on the nature of the scan.

Will I have to change my clothes?
Patients may be asked to wear a gown for some scans. In addition, removal of glasses, jewelry, dentures, hearing aids, or anything else that could interfere with the scan may be required.

This procedure can be performed at either Adventist Medical Center or here at Gresham Imaging Center.
