Prepare for Your
Computerized Tomography (CT)

A CT scan is like an MRI in that it provides a cross-sectional view of the body, creating multiple images. Our state-of-the-art, multi-slice CT scanner utilizes low levels of radiation. CT is a fast, gentle and painless method of examining the human body.

CT scan

Before the CT scan:

  • Please let us know if you are nursing or may be pregnant
  • Please arrive 30 minutes early for registration verification
  • Bring previous imaging studies with you to your exam (MRI or CT reports and images)
  • If you are having a non-enhanced scan (no contrast medium), eat or drink as you normally would
  • If you are having an enhanced scan (with contrast medium):
    • Please inform the MDC nurse if you have any allergies
    • You will be advised not to eat or drink 2-4 hours before the exam, depending on the body area being scanned
    • You will be asked to arrive 30 minutes to 2.5 hours early
    • The contrast medium may be given either orally or injected through an IV into your arm
    • After the contrast medium is given, you may notice a metallic taste in your mouth that will last a few minutes
    • Following an enhanced scan, you should drink more liquids than usual
  • If you have questions or require more information about your exam, please feel free to contact an MDC nurse at 612.879.1528 (8 am - 4 pm)

During the CT scan:

  • During the examination you will be lying on a comfortable patient table
  • The table will slowly move you through the CT opening called the gantry
  • A built-in intercom allows you to talk with your technologist any time during your exam
  • The entire exam will take 15 to 30 minutes

Test Results:
Following the CT examination, a radiologist analyzes the images and sends a report to your doctor, who will then discuss the results with you

Computerized Tomography (CT) is only available at MDC Minneapolis.
