Diagnostic ultrasound of the foot and ankle is a real-time imaging modality
that has been incorporated into many podiatric medical practices.
The
scanner generates specific frequency ultrasound waves, which are pulsed and
transmitted through a probe at specific timed intervals into the body. The
echoes are then captured by the probe, translated into images by the scanner.
This process is called Pulse-Echo imaging.
Common
podiatric uses for diagnostic ultrasound includes its application for
diagnosing intermetatarsal neuromas, tendon pathology including tears and
ruptures, plantar fibromas, cysts, bursitis, ligament pathology including
sprains and tears, plantar fascia pathology including tears. Foreign bodies
including metallic and nonmetallic, muscle trauma, joint capsulitis, various
tendons including the Achilles, anterior and posterior tibial, extensor
hallucis longus, and peroneals, stress fractures, arthritis, and many more
conditions too numerous to mention.
