What is a computed tomography (CT) scan?

A CT scan is a non-invasive medical procedure used to help diagnose and treat medical conditions. It combines the use of high-tech computer systems and X-rays to obtain specialized images of your brain, organs and/or bones. CT scans provide greater clarity and reveal more detail than X-rays alone, which is why they are beneficial for medical diagnosis and treatment. They are painless, fast and easy. Scanners are open on both sides, putting many claustrophobic patients at ease.

How is a CT performed?

  • For some exams, you may be given a contrast agent orally or via IV.
  • You may be asked to change into a gown and remove all jewelry.
  • You will be positioned on a moveable exam table, and the technologist will step into a control room.
  • You may notice a mechanical noise from the scanner. This is just the activation of the X-ray tube and its rotation around the body.
  • The technologist may ask you to hold your breath during some portions of the exam.
  • Results from the CT scan will be sent to your ordering physician within 24 to 48 hours. Upon request, CDs or films can be printed following the exam.
