A CT scan, or CAT scan, is a common term for computerized tomography, a painless 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.

Why is This Exam Done?

Your doctor has requested a computed tomography scan (CT) of your brain. CT scans use X-ray technology and advanced computer analysis to create detailed pictures of the neck area. This technology, called cross-sectional imaging, allows the imaging physician to take highly detailed images and to assess your neck for any tumor, masses, or any abnormalities.


What Will Happen During the Exam?

  • While positioning you on the exam table, the technologist will explain your procedure and answer any questions you may have.
  • You will be asked to lie flat on your back. Your arms will be positioned at your sides. You will be asked to hold very still.
  • If you are receiving contrast, it may be given through an injection in an IV placed in your arm.
  • 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.
  • The table you are on will slide into the scanner. Only your head and neck will be covered by the scanner. 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.
  • This procedure usually takes approximately 15 to 20 minutes.
