A CT scan is an x-ray procedure that is enhanced by a computer and gives out a three-dimensional view (referred to as a “slice”) of a particular part of the body.
Why is CT used?
While dense tissue can block some areas during standard x-ray image procedures, CT scans create a three-dimensional view by using a computer to combine different slices, showing all bone and tissue.
What Can I Expect?
Contrast media is given to highlight various body parts and passes through the body within a day or two. It is usually given by mouth or injection. It is normal to feel a warm sensation as the dye makes its way through your body. The exam can last anywhere from 30-60 minutes while the computer generates the image. Radiation exposure and procedure times can vary depending on the factors relating to your case.
The radiologist, a specialized physician, will study the results of your exam and discuss them with your doctor who will then consult with you.
