Conventional X-rays are the most basic type of radiography. A podiatrist can use basic X-ray images to diagnose bone fractures and other conditions that primarily affect the bones. Other techniques must be used to fully evaluate soft tissue problems not involving the bones.
Ultrasound imaging uses high frequency sound waves rather than electromagnetic radiation to generate images of the feet and lower legs. Ultrasound imaging can help to diagnose problems with muscles and other soft tissues. Images can be recorded in real-time to help with diagnosing joint alignment problems.
CT scans, use multiple X-ray images to create cross-sectional images and 3-dimensional images. CT scans can be used for scanning smaller areas like the feet and lower legs. CT technology is useful to podiatrists when simple X-rays do not provide the level of detail needed for accurate diagnosis and treatments.
