Computed Tomography

What Is Computed Tomography?

Sometimes a podiatrist may prescribe a computed tomography (CT) examination (also known as a “CAT scan”) to help diagnose and treat a foot or ankle problem. A CT is a kind of X-ray device that takes cross section images of a part of the body, giving the physician a three-dimensional image:

Common foot problems a CT exam can address include:

• Arthritis
• Deformities
• Flat feet
• Foreign bodies
• Fractures
• Infection
• Tumors

CT scans are often superior to conventional X-rays because they can more accurately pinpoint a suspected problem.

Pregnant women, especially those in their first trimester, are advised against having a CT exam or any X-ray examination.
