A CT scan (computed tomography scan) is an imaging scan. It uses X-rays and a computer to make detailed pictures of different areas inside the body. A CT scan can give more information than a regular X-ray exam. A CT scan provides data about internal organs, soft tissue structures, blood vessels, and bones.
In this procedure, the pictures will be taken in a large machine that has an opening (CT scanner). Depending on the type of exam, a substance called contrast dye may be used to help see the area in the body that is being checked. The contrast may be swallowed, injected through an IV, or in some cases, given by an enema. An enema is when the dye is put into your colon through your anus.
The procedure may vary among health care providers and hospitals.
