Computed Tomography (CT/CAT) Scan

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

UR Imaging utilizes low-dose CT scanners, which significantly decreases the level of radiation exposure to the patient while maintaining high image quality.

Children can take a virtual tour of their CT study at https://www.urmc.rochester.edu/childrens-hospital/tests-procedures.

Important:

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 need to cancel or reschedule your appointment, please provide 24 hours notice.

We ask that you call at least 3 days ahead if either of the following pertain to you so we may make the appropriate modifications to your treatment plan:

  • If you believe you may be pregnant.
  • If you have had a contrast allergy/reaction (i.e., hives, rash, itching, breathing difficulty) while undergoing a previous imaging study.

Instructions for the day of your procedure

  • Please arrive on time. Allow extra time in your trip for weather, traffic and parking.
  • 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 prior to administering contrast. 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 for approximately 30–60 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.

What to expect after your procedure

  • You will be provided with post-procedure instructions.
  • Your results will be sent to your referring physician within 2 business days. Please contact your physician.
