Computed Tomography (CT Scan)

A Computed Tomography (CT) Scan is a diagnostic imaging procedure that uses a combination of a rotating x-ray scanner and sophisticated computers to produce a series of two-dimensional and three-dimensional images, allowing our experienced doctors to look at organs, bones, blood vessels and soft tissues inside of your body.

At Rochester Regional Health, our Radiology team uses state-of-the-art CT scanners and software to capture incredible detail in milliseconds, while using less radiation than other typical scanners.

Specialized CT Scans at Rochester Regional Health

Specialized CT scans performed at Rochester Regional Health include, but are not limited to:

CT Virtual Colonoscopy – An alternative to a conventional colonoscopy, a CT virtual colonoscopy uses a CT scan to create detailed images of the tissues inside the colon. It does not require sedation, injections or the insertion of a camera into the colon, and the procedure takes less time than a traditional colonoscopy
CT Angiography – A medical test that combines a CT scan with an injection of a special dye (contrast) to produce pictures of blood vessels and tissues in your body. The contrast highlights blood vessels making them easier for our doctors to study. CT angiography is often used to study blood vessels in the brain, abdomen, kidneys and lungs.
CT Enterography – A test which uses a CT scanner and contrast material to view the inside of the small intestine. CT enterography is useful in the evaluation of inflammatory bowel disease, Crohn’s disease, gastrointestinal bleeding and some gastrointestinal tumors.
Stroke CT Imaging and Treatment – Our RGH Radiology team was recently certified by the American Heart Association and was the first in New York State to receive thrombectomy certification.

CT Scan FAQs

If you are having a CT exam you will be given specific instructions when you make your appointment. Below are common preparation tips:
- In most cases, do not eat or drink for two hours prior to the scan.
- Some CT scans require oral, IV, and rectal contrast material. The need for recent blood work within 30 days may be required to receive this contrast material.
- You can take all of your prescribed medications as scheduled unless otherwise instructed.
- If your doctor provides you with a requisition form, please bring it with you to your appointment scan. When you arrive, you will be asked to fill out a questionnaire in order to confirm that all necessary precautions have been taken.
- Most CT exams require approval from the insurance company prior to the visit. Please check with your referring provider and/or insurance company to confirm that the exam will be covered.
- Please inform the technologist or nurse if you are pregnant or think you might be pregnant, if you have kidney disease or are diabetic, or if you are allergic to the IV contrast.
CT scans may be performed on an outpatient basis or as part of your stay in our hospitals. Procedures may vary depending on your condition.

In general, one of our highly skilled technologists will help position you on the CT examination table. Once the exam begins, the table will slowly move through a circular opening as the scanner rotates around you, taking x-rays. You will be asked to remain still, and depending on the test, you may be asked to hold your breath during the exam. While you will be alone in the exam room during the actual scan, you will be able to see and hear the technologist at all times.

CT scans may or may not be done with contrast. Contrast may be administered through an IV line placed in your hand or wrist prior to the exam.
In most cases, you can return to your regular activities. Additional instructions may be given after the test, depending on your particular situation.

If contrast was used during your procedure, you may be monitored for a period of time for any side effects or reactions.

Our radiologists will review your test results and will send them to your doctor to discuss the results and any next steps with you.
Please know that CT scans have far more benefits, including a more accurate diagnosis, that outweigh any potential risks.

During CT scans, you are briefly exposed to radiation. While excessive exposure to radiation can be harmful, the exposure during a CT scan is minimal.

Women should always inform their physician and the technologist if they are pregnant or may be pregnant. Nursing mothers should wait 24 hours after receiving contrast before resuming breastfeeding.

Allergic reaction to contrast (mild or severe) is also a rare but possible risk. Our team is well-prepared to deal with such reactions should the need arise.
