Sometime, 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 sectional images of a part of the body, giving the physician a three-dimensional image: A CT scan is an x-ray that takes many pictures, like slices, in three planes of your foot. It is used to "visulaize" tumores, infections, complex fractures. It can help guide treatment.
Common foot problems a CT exam can address include: arthritis, deformities, flat feet, foreign bodies, fractures, infection, and 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.
