What is a CT Scan

The CT scan, or Computed Tomography scan, is an advanced diagnostic test that uses X-rays, a special scanner and a computer to produce detailed images of a specific area of your body. These images, when studied in sequence, can give your provider a 2-D view of your body.

How Does a CT Scan Work?

The scanner is made up of a ring containing an X-ray tube and receptors. The part of your body your provider wants the radiologist to see will be placed within the ring and the X-ray tube rotates around you. With each rotation the tube sends X-rays and the receptors measure the amount of X-rays absorbed. The computer then transforms these measurements into a visual image. This image is viewed on a computer screen during the exam and later converted to digital media for the radiologist and your provider to study.

What Can I Expect

Different types of CT exams have different preparation instructions. Your provider and/or our imaging center will provide you with specific instructions for your particular exam prior to your appointment. For any type of CT exam please remember to:

  • Wear comfortable, loose fitting clothing. If needed we will provide you with a hospital gown or scrubs to change into for your exam.
  • Tell your provider and the technologist if you are allergic to, or have ever had a reaction to, iodine contrast material.
  • Tell your provider and technologist about any medications you are taking.
  • Tell your provider and technologist if you are pregnant, think you might be, or are breastfeeding.
  • You may be asked to remove any hairpins or jewelry that may interfere with your CT exam.
