CT Scan Preparations by Hill Medical

What preparation is required before the CT scan?

Depending on the type of study, you may also receive a contrast medium. This is a dye that increases the quality of the CT images. The contrast medium may be administered orally, or by injection, or both. Some patients report a warm feeling or an unusual taste in their mouth from the contrast medium.

For abdominal and/or pelvic CT exam – have nothing to eat or drink for the 4 hours prior to your exam. Also, you will need to drink an oral contrast mixture before arriving for your appointment. If this mixture is not available at your doctor's office, you may pick it up at our office. This mixture makes certain internal structures easier to see during the exam. Any medication prescribed by your physician should be taken as directed.

For some CT exams, contrast may have to be injected into your veins (IV contrast). Many exams do not require any contrast at all.

Should I tell the technologist about my medical history?

Yes. Before you are given an IV contrast, be sure to tell the technologist if you have allergies, asthma, heart problems, diabetes, or kidney problems; if you think you might be pregnant; or if you are currently undergoing any radiation therapy.
