CT Extremity Scan

If there is a possibility of pregnancy, please inform the technologist prior to the date of your examination. Please advise our department prior to your procedure if you have allergies or previous contrast media reaction.

What to expect

Your physician has requested that you have a CT (Computerized Tomography) Scan. This procedure is done to produce detailed images of a selected part of your body. You will be positioned on a table that moves through the scanner. It is very important that you lie still while the images are being taken.

On the day of your exam

Please arrive approximately 15 minutes prior to your appointment time to allow for parking and registration. Please plan to spend approximately 1-2 hours in our department. If you bring friends or family to the appointment they will be asked to wait in a waiting room during your scan. Children cannot be left unattended during your scan. Please arrange for a caregiver

Preparation and procedure

There are no preparations for the following exams:

  • Upper Extremity without contrast
  • Lower Extremity without contrast

The following exams require an injection of contrast media into a vein in your arm. Please see further directions under contrast studies.

  • Upper Extremity with Contrast
  • Upper Extremity with and without Contrast
  • Lower Extremity with Contrast
  • Lower Extremity with and without Contrast

Contrast studies

You may be required to have a blood test prior to the examination to determine kidney function. The final determination of contrast administration is typically decided by the radiologist. At times the scan is changed from contrast to non-contrast or vice versa on the day of your exam. If this should occur and you have not had a lab test, the imaging department will help to facilitate this step.


Our radiologist will study your examination and a report will be forwarded to your practitioner, from whom you may obtain the results. If you have any questions regarding this procedure, please contact our department at 608-342-4740.
