CT of the Chest

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.

Why is This Exam Done?

A chest CT scan provides detailed pictures of the size, shape, and position of your lungs and other structures in your chest and can determine if there is a lung problem or other condition.

The CT scan helps find the cause of any symptoms you may be having such as chest pain, excessive cough or trouble breathing. It looks for problems such as tumors, excess fluid around the lungs, and blood clots. It can also check for conditions such as tuberculosis, emphysema, and pneumonia.


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 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.
  • 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 15-20 minutes.
