A CT scan uses X-rays and a computer to create detailed images of organs, bones and other tissues in cross section like slices. It provides more detail than a regular X-ray.
The entire procedure usually takes between 0 to 60 minutes, depending on what part of the body is being scanned.
After the scan is finished, a radioligist will study your images and dictate the findings. Your physician will then review the report and discuss it with you.
CT scan is a safe imaging test. However, it exposes you to a small dose of radiation. For most people, such a small potential risk far outweighs the benefits, in terms of saving your life.
