Computed Tomography (CT)

Computed Tomography (CT) also known as CT or a CAT scan, is a type of x-ray that provides detailed, cross-sectional (sliced) images of the body. A primary advantage of CT imaging is that it can be done on all types of body tissue (such as muscle and bone) without sacrificing clarity.

A special dye, also known as contrast or iodine, may be used during your exam, to highlight your blood vessels and organs. This will provide more detailed information to your doctor.

Please notify the technologist if you are allergic to Iodine, or think you may be.

Women should always inform their doctor or technologist if there is any possibility that they are pregnant.‚Äč

How do I prepare for a CT?

  • If your exam requires a contrast injection, nothing to eat or drink 4 hours prior to exam.
  • If your exam does not require a contrast injection, there is no prep needed.
  • Follow your normal daily routine unless your provider tells you otherwise.
  • You'll be asked to remove your watch, jewelry, hearing aids, pens, eyeglasses, and other metal objects.
  • Bring a list of your current medications you are taking.
  • Wear loose and comfortable clothing with no metal zippers or buttons.
  • Prior to the appointment, check with your physician to see if lab work is needed.
  • Arrive 30 minutes prior to appointment time to register and complete necessary paperwork.

What to expect?

  • Most CT exams take 15-30 minutes. Depending on the type test you are having, the test may take longer. Give yourself extra time to check in.
  • Please arrive 1 hour early when having an Abdominal or Pelvic CT. You may be asked to drink an oral contrast cocktail, 1 hour prior to your exam time.
  • Results will be sent to the referring physician within 24-48 hours.
