CT/CAT Scan (Computed Tomography)

Make Appointments & Get Care

What is a Computed Tomography (CT/CAT) Scan?

A Computed Tomography (CT) scan is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce vertical and horizontal images (called slices) of the body.

CTs show detailed images of any part of the body, including bones, muscles, fat, organs, and blood vessels.

UR Medicine's Department of Imaging uses low-dose CT scanners, which significantly decrease the level of radiation exposure to the patient while maintaining high image quality.

UR Medicine's Approach

Appointment Information

You may receive a call from us to review your medical history to determine that no issues exist preventing you from having a CT scan.

If you believe you may be pregnant, or if you have had a contrast allergy/reaction (i.e., hives, rash, itching, breathing difficulty) while undergoing a previous imaging study, we ask that you call us at least three days ahead of your appointment.

Instructions for the Day of Your Procedure

  • Please arrive on time. 
  • Remove and leave all jewelry and/or metal at home.
  • Leave valuables at home.
  • Bring your insurance card and photo ID.
  • Generally, fasting is required. You will be advised of your fasting requirement at the time of scheduling.
  • A parent/guardian should remain in the building when a child (under 19 years) is having an imaging procedure.
  • All parents/guardians having an imaging study must be aware that there is no supervision available for children. Please do not have children accompany you to your appointment.

What to Expect

The Day of Your Procedure

  • You will be asked to remove all jewelry and metal.
  • Some CT scans require drinking an oral contrast. This would occur approximately 30 to 60 minutes prior to your scan.
  • Some CT scans involve an injection of contrast. If this type of contrast is needed, an IV will be inserted.

After Your Procedure
