A computed tomography scan, also called a CT or CAT scan, combines several X-rays to gather a clear picture of your bones, tissues, and blood vessels. With the aid of a computer, a CT scan can generate cross-sectional views of your internal structures to create a level-by-level view of your body. Essentially, these image “slices” can provide more detailed information than plain X-Rays can.
Your doctor may recommend a CT scan to investigate the extent of an injury or other concerning symptoms.
Physicians order CT scans for many different reasons. Your doctor may recommend a CT scan to:
If you have an existing condition, such as cardiovascular disease or bone cancer, your doctor may use CT scans to detect any concerning changes to your health.
The simplest way to understand how a CT scan works is to compare the body to a loaf of bread. Each X-ray captures a slice to see the crust (outer layers) and the internal center. Repeating this process several times allows your doctor to create a full picture of your internal structures from all angles.
Because CT scans use computer imaging, they can also stack images to generate a 3-D picture.

After putting on a hospital gown, you lie on the CT scan table. As the machine scans around your body, it’s important to remain still. Movement can disrupt the image, so your technologist may even recommend holding your breath at some points. The entire process can take anywhere from a few minutes to 30 minutes.
