    CT scans use a rotating x-ray unit along with a computer to create detailed cross-section images (like slices of bread) of the inside of your body. Once used primarily to visualize the brain, CT scans are now used to look at injuries like complex fractures and images of the abdomen and lungs. 3-D image models of your organs are created by stacking the individual images together. This technology allows physicians to identify injury and disease.

    CT scans usually take 5-10 minutes. If you are scheduled for a scan with oral contrast, there is an hour wait before the scan begins while the contrast material circulates through your body. Contrast highlights specific areas inside your body to create a clearer image. Often your doctor will request additional IV contrast be administered through a vein in your arm or hand. Littleton Adventist Hospital practices ALARA principles to provide the lowest possible radiation dose to our patients and high quality images for physicians.

    American College of Radiology Accreditation Seal Please let the technologist know if you:

    • Are pregnant or think you may be pregnant.
    • Have an allergy to iodine. Contrast material with iodine may be used with the scan.
    • Have a history of kidney disease.
    • Are diabetic and taking a medication containing Metformin. It is important for you to speak with your physician before and after the exam to discuss discontinuing and resuming any medication.

    Helpful Tips for our CT patients

    Scheduling an Appointment

    We want to make the scheduling process as easy and convenient for you as possible. A CT exam requires a physician referral. Once we receive the order for the CT from the referring physician we will call you to schedule an appointment and complete the necessary registration over the phone. With pre-registration complete you will then need to arrive the day of your appointment only 15 minutes prior to your scheduled appointment time. Sometimes the urgency of the test precludes pre-registration and then we ask that you arrive 30 minutes prior to the time of your appointment to complete the necessary paperwork. Please bring your insurance card, photo ID and co-payment, as insurance co-payments are due at the time of service.

    What to Expect

    The CT technologist will assist you onto a padded table. The table will move slowly up and into a large, doughnut-shaped opening. You may be asked to briefly hold your breath during the scan to ensure the best possible images. While you will be alone in the room during the scan, the technologist will be able to see, hear, and speak with you at all times.

    What to Bring

    We advise that you only bring essential items to the hospital. Please leave all valuables including jewelry and cash at home. We recommend you bring the following documents: health insurance card(s), picture identification (driver's license or state ID), credit card or check for insurance co-payment, list of medications you take, prior test results or medical records (if requested by your physician) and any worker's compensation information including billing address and claim number (if applicable).

    Parking/On-site Directions

    Convenient parking and entry for patients is located on the east side of the hospital, at the doors marked Outpatient Center, just south of the main hospital doors.

    What to Wear

    You don't need to bring any additional clothing or dress any differently than you normally would. Clothing with metal will need to be removed prior to the exam. Dressing rooms with gowns and lockers are available for personal items and valuables.


    Preparation for a CT will vary depending on whether it is with or without IV contrast but your physician or scheduler will advise you of any special preparation required at the time the appointment is scheduled.


    Your CT results will be sent to your referring physician. For your records we are happy to provide you with a copy of your test on CD.
