Ultrasound in sports medicine.

Musculoskeletal sonography has been shown to be effective for many applications related to sports medicine. Some advantages of sonography over MR imaging include portability, accessibility, high resolution, and relative lower cost. More importantly, dynamic imaging under sonography visualization allows diagnoses that cannot be made with routine MR imaging. Additionally, direct imaging correlation with patient symptoms provides important information to the referring clinicians. The disadvantages of sonography include operator dependence and long learning curve. This can be minimized, however, with proper training and standardized technique. Musculoskeletal sonography has proved itself as one of several imaging methods invaluable to the diagnosis of sport medicine-related abnormalities.
