Ultrasound is a very effective tool for diagnosing a wide variety of foot and ankle problems, particularly soft tissue problems. Ultrasound uses sound waves on the body in a way much like radar uses sound waves. The waves hit a targeted area and are bounced back to a recording device, which produces an image. Ultrasound is a completely safe, noninvasive, and painless diagnostic procedure.

Common problems for which ultrasound may be prescribed include:

• Bursitis.
• Heel spurs or plantar fasciitis.
• Injuries of the ligaments, tendons, or cartilage.
• Morton's neuroma.
• Presence of foreign bodies.
• Soft tissue masses.
• Tarsal tunnel syndrome.
• Tendonitis or tears in a tendon.
