CT/Cat Scan

CT/Cat Scan

CT uses X-rays and computer technology to create images of bones, organs, and blood vessels. CT images help doctors assess conditions and trauma, guide procedures, diagnose cancers or fractures and determine treatment.

Patient Preparation

The preparation for your CT exam will depend on the body part to be scanned. Contact us to find out if you have any restrictions on what you can eat or drink before your appointment. Tell your technologist if you have allergies or if you may be pregnant.

What to Expect

CT is painless, and usually lasts only a few minutes. We may ask you to change into a hospital gown for the exam. You will lie still on a table as it gently moves you through the scanner.

Your exam may require an intravenous (IV) or oral contrast agent to improve image quality. Tell your technologist if you have allergies, especially to iodine or shellfish. After your scan, the contrast agent quickly leaves your body.

Your technologist will step into a control room to conduct the scan. You can talk to the technologist via intercom. Family or friends are not permitted to stay in the CT room.

During the scan, you may hear noise coming from the scanner. This noise is the X-ray tube rotating around your body. You may be asked to hold your breath for a few seconds during the exam. Remain still, as movement may require that the exam be repeated.

After your exam is complete, the radiologist will review the scans and forward results to your doctor.
