X-rays are a diagnostic test that shows infection, injury, and disease in the bones. A podiatrist will use X-rays to properly diagnose and treat problems with the bones of the foot and ankle. X-rays can reveal abnormal bone growth or changes and can monitor the alignment of bones as they heal after a fracture. X-rays are also used to reveal foreign objects that have penetrated the skin and tissue. X-Rays also help Podiatrists to see the underlying foot structure of the patient which helps the Podiatrist diagnose certain conditions such as flat foot deformity.
