For your CT Exam

What will the CT exam be like?

You will meet with an Open Air MRI technologist whose primary concern is your care and well-being. Our technologists have completed a rigorous course of education and training, and they work under close supervision of our radiologists to assure the most accurate results from your examination.

Prior to the start of your CT exam the technologist will explain the procedure to you. This is done for two reasons: to put your mind at ease as to what is taking place and to ask for your cooperation. Simply follow the instructions of the technologist for a relaxed examination and to achieve the desired results.

Next, you will be gently positioned and secured on the scan table. It is important that you be secured, because even the slightest movement can blur the picture and result in the need for repeated scans.

Then, you will be moved into the scanner. The technologist will have you in full view at all times and be in constant communication via two-way microphones. During this brief time, you will hear the humming of the equipment as it produces the images. You may also feel slight movement of the table as it prepares for the next scan.

  • Some CT scans may require an oral contrast media or IV contrast media depending on the nature of your scan. This substance is given to highlight various body parts.
    • Oral Contrast - this is given to illuminate the bowel. It helps to make the internal organs more distinguishable. This contrast is taken orally.
    • IV contrast - contrast that is injected into the patient by way of the veinous system. This contrast helps with viewing arteries and veins. Let the nurse or technologist know if you have ever had an allergic reaction to any injected dye.
  • For scans of the abdomen or pelvis, you may need to drink a diluted barium solution. Your nurse and/or technologist will let you know how much to drink and when.
  • The actual CT exam will take about 15 to 45 minutes depending on the type of CT. This includes the preparation time and the time it takes the computer to generate the image. Actual exposure time is minimal.
  • The machine will move you into the correct position and the technologist will talk to you by way of a two-way intercom.
