What is a Computerized Tomography Exam (CT)?

A CT Scan produces a series of cross-sectional images of a selected part of your body or head that will be interpreted by a radiologist.

A CT Scan, sometimes called computer axial tomography (CAT), is a painless and  non-invasive medical test that helps physicians diagnose and treat medical conditions. Computerized Tomography is a diagnostic X-ray procedure that marries traditional X-ray technology to the new computer technology modern medicine has grown to rely upon. This procedure produces a series of cross-sectional images (also called ‘slices’) of a selected part of your body or head that will be interpreted by a radiologist.

What Can I Expect During My CT Scan?

  • Prior to the start of your exam, the technologist will explain the procedure to you and put your mind at ease with what you are going to experience.
  • If you wear clothes without any metal, you will not have to change into an exam gown.
  • You may be asked to remove any dentures and/or jewelry if they are in the area you are having scanned.
  • Depending on the type of scan you are having, you may be asked to lie on your back or stomach. You will need to lie very still as any movement causes blurring of the images. The table will then slowly move through the scanner. You will be given breathing instructions by the technologist while the images are being acquired.
  • Certain CT scans include a Contrast Injection of a special type of dye that highlights the region of the body being scanned.
  • The actual CT scanning process is painless. You will not feel the x-rays.
  • You are able to communicate with the technologist throughout the procedure via intercom.

How Long Will the CT Scan Take?

CT scans typically take anywhere from 10 to 20 minutes, depending on the type and/or combination of exams the doctor has ordered.

What Will Happen Following the CT Scan?

  • A radiologist will review your CT scan. The radiologist will send a report to your physician within 24-48 hours, who will give you the results of the scan.
  • You can resume your regular diet immediately after the scan unless otherwise told by your doctor. If you have received the IV contrast, you may be asked to drink extra fluids during the rest of the day.
