A computerized tomography (CT) scan combines a series of X-ray images taken from different angles around your body to help detect a variety of diseases or conditions. Compared to regular X-rays, the images are more detailed and give a clearer picture.
Why a CT Scan?
Your doctor may recommend a CT scan to help:
- Diagnose muscle and bone disorders, such as bone tumors and fractures
- Pinpoint the location of a tumor, infection or blood clot
- Guide procedures such as surgery, biopsy and radiation therapy
- Detect and monitor diseases and conditions such as cancer, heart disease, lung nodules and liver masses
- Monitor the effectiveness of certain treatments, such as cancer treatment
- Detect internal injuries and internal bleeding

How to Prepare
Please arrive 45 minutes before your scheduled appointment allowing the appropriate time for check-in and oral prep. Also make sure to follow all instructions provided by your healthcare provider, including:
- Do not consume any solid food for 4 hours before your scheduled appointment time
- You can drink liquids such as non-carbonated water, juice, black coffee or tea
- Remove metal objects, such as a belt, jewelry, dentures and eyeglasses, which might interfere with image results
- If you have had recent blood work, including a BUN/creatinine test done at an outside hospital within 3 weeks of your exam, please bring a copy of the results with you
What to Expect
CT scanners are shaped like a large doughnut standing on its side. You will lie down on a narrow, motorized table that slides through the opening into a tunnel. Straps and pillows may be used to help you stay in position. During a head scan, the table may be fitted with a special cradle that holds your head still. While the table moves you into the scanner, detectors and the X-ray tube rotate around you. A technologist will monitor from a separate room and you will be able to communicate with the technologist via intercom.
To ensure your safety, a blood test may be required prior to an injection of CT contrast. We will review your medical records to determine if a blood test is required.
