CT of the Spine

In This Page:

 


A CT scan, or CAT scan, is a common term for computerized tomography, a diagnostic imaging test that displays two and three dimensional images of internal structures of the body on a computer screen. Cat Scan uses a narrow beam of X-rays and high-powered computers to generate images of bones and soft-tissues in the body and spine.

Why is This Exam Done?

A CT scan of your cervical- thoracic -and lumbar spine allows the radiologist to look at different levels or slices of the middle back using a rotating X-ray beam. The radiologist is able to view each slice to assess for injuries, including ruptured disks and other bony abnormalities.


What Will Happen During the Exam?

  • While positioning you on an exam table, the technologist will explain your procedure and answer any questions you may have.
  • If contrast dye is being used, it will be injected through your IV.
  • During the injection, you may experience a warm sensation all over your body and a metal taste in your mouth. This is normal.
  • If you experience any itching, sneezing, nasal congestion, scratchy throat or swelling of your face, please notify the technologist immediately.
  • You will be asked to lie flat on your back.
  • The exam table will slide into the scanner, only covering the part of your body which is being studied. The scanner is open at the back and the front, allowing you to see out.
  • The technologist will always be able to see and hear you during your exam.
  • You may be asked to hold your breath for a short time while the scanner takes a series of pictures. The time it takes to actually acquire images is very brief.
  • The images will be reviewed, and if necessary, some may be repeated.
  • This procedure usually takes approximately 20 minutes.
