Computed Tomography (CT)

What is CT?

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

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

General Preparation Tips

Many CT exams involve the use of common contrast agents, a substance used to increase the contrast of structures or fluids within the body in medical imaging. Here is what you need to know prior to your exam:

• If you have had an allergic reaction to x-ray contrast, please contact our nursing department as soon as possible prior to your appointment. Additional bloodwork or preventative pre-medication may be required.
• Please do not eat or drink anything (including water) for at least 2 hours prior to your scheduled exam time.
• Please bring all relevant insurance information, referral paperwork, and copies of X-rays and/or prior exams.

For Abdominal or Pelvic CT Scans

• Please arrive 30 minutes before your scheduled exam time.
• Please note that intravenous contrast may be used.
• The estimated length of your entire appointment will be 60 minutes.

For CT Scans of All Other Areas

• Please arrive at least 15 minutes before the scheduled time of your exam.
• The total expected length of your exam is approximately 15 to 30 minutes.
