Before Your Appointment During Your Appointment After Your Appointment

Whether you’ve received a referral for a CT scan or are exploring your options on your own, we’re here to help you understand what comes next. This page covers everything you need to know about a CT scan— from how to prepare beforehand, to what to expect during the exam, and how to proceed afterward.

What is a CT (Cat scan)?

A CT scan uses x-rays and computer technology to take pictures inside your body. It provides more detail than a standard x-ray and can show organs, blood vessels, bones, and tissues.

Some CT scans use contrast (dye) to help highlight specific areas. The dye may be swallowed, injected, or both.

Check-In and Patient Verification: Your safety is our priority—we’ll verify your information when you check-in.
Changing: If your clothes contain metal, we’ll ask you to change into a gown.
Contrast (if needed):

IV contrast: A nurse or technologist will place an IV before your scan and remove immediately after the exam.
