Computed Tomography

What is Computed Tomography (CT)?

Computed Tomography (CT) is a medical imaging method that uses the help of a computer to generate two- and three-dimensional images of the inside of an object from a large series of two-dimensional x-ray images. A traditional CT scan can be used for a variety of patient diagnoses, including cardiac, neurological imaging and full-body imaging.

Experienced Technologists

Our CT Technologists are certified and registered with the Washington State Department of Health, as well as with the American Registry of Radiologic Technologists (ARRT), as Radiologic Technologists. All of our CT Technologists have advanced certification in CT.

Before Your Test

  • Be sure to mention the medications you take and ask if it is okay to take them before the test
  • If instructed, stop eating and drinking four hours before your CT
  • If instructed, drink contrast (a liquid that improves the image) as directed, before your CT
  • The test may take anywhere from 10 minutes to two hours, depending on whether contrast is used and the particular part of the body being scanned
  • Arrive on-time to check in
  • When you arrive, you may be asked to change into a hospital gown
Tell the technologist if:
  • You have allergies or kidney problems
  • You take diabetes medication
  • You are pregnant or think you may be
  • You ate or drank anything prior to the test

During Your Test

  • You may be given contrast through an intravenous (IV) line or by injection
  • You will lie on a table, which slides into the CT scanner
  • The Technologist may ask you to hold your breath for a few seconds during your scan

After Your Test

  • You can go back to your normal diet and activities right away
  • Any contrast will pass naturally through your body within a day
