An ultrasound scan, also known as a sonograph, is a medical test that uses high-frequency sound waves to capture live images from inside the body. There is no exposure to radiation with with this imaging modality. Ultrasound allows the doctor to see problems with joints, tendons, and ligaments in real-time. If you need an injection, ultrasound guidance guarantees accurate and precise needle placement. Ultrasound is also used to diagnose and monitor the treatment of plantar fasciitis, neuroma, and other soft tissue cysts or swelling. It helps identify conditions that were previously only visible with MRI imaging, including Achilles tendon injuries, plantar fascial tears, and the location of foreign bodies.
