Learn About Computed Tomography (CT/CAT Scan)
Norwalk Radiology Consultants with Stamford Health offers state-of-the-art imaging. Our full-service diagnostic center is dedicated to providing patients with the highest-quality personalized care at a lower out-of-pocket cost.
Our board-certified radiologists are highly trained in computed tomography (CT or CAT scan) to deliver accurate, detailed diagnostic information in a person-focused environment. CT scans are exams that use a special X-ray tube to produce a series of computerized images of the body that do not appear on traditional X-rays. This type of scan can help to locate or identify disease or injuries like tumors, embolisms, or complex bone fractures. This scan is also used for cardiovascular, neurological, and lung imaging.
A referral is required to schedule a CT scan; all results will be communicated through the referring physician.

What should you expect during a CT or CAT scan?A CT scan can take 10-30 minutes depending on the area of the body being scanned. A patient must remove all metal objects and jewelry during a CT scan; patients may be asked to change into a gown depending on the type of scan needed.
During the CT exam, a patient will lie very still on a table that slides into the circular opening of the machine. A CT machine makes quite whirring, buzzing, and clicking noises, as the X-ray tube rotates around the body and takes pictures.
CT scans sometimes require the use of contrast media, either intravenously and/or by mouth, to enhance blood vessels and organs and highlight the area being imaged. If the contrast material is administered intravenously, an IV is inserted into an arm vein. If a patient is asked to drink contrast, they may pick it up in advance from our facility or arrive one to two hours ahead of your scheduled appointment time to drink the contrast. -
What do you need to know prior to a CT exam?Some patients may have conditions that warrant a conversation with their doctor or may require bloodwork, before a scan. For diabetic patients receiving IV contrast, it is advised that they eat a small meal no less than two hours prior to the appointment. All prescribed diabetes medications can be taken prior to the appointment. If they have a glucose monitor in the area that will be imaged, it will need to be removed prior to exam.
If a patient is pregnant or think they may be pregnant, please discuss the CT scan with the ordering physician prior to the scheduled appointment.
A small percentage of the patient population may be allergic to contrast material. If a patient has a history of several severe allergies, a prior reaction to CT contrast, or a history of an allergy to iodine, please consult with the referring physician prior to the appointment. -
Does insurance cover a CT scan?Please discuss with your referring physician; all insurances offer different coverage and some require prior authorization.
