The clinical use of Musculoskeletal (MSK) ultrasound (US) has increased significantly largely due to its diagnostic accuracy for many indications and its significantly lower cost than other cross-sectional imaging modalities. In the United States in 2009 radiologists interpreted 91,022 MSK ultrasound studies compared with only 40,877 in 2000 . MSK ultrasound has excellent resolution for soft tissue applications, making it a good choice to diagnose conditions such as partial or full thickness tendon tears, nerve entrapments, muscle strains, ligament strains, joint effusions, etc . However, despite its rising use, there is a relative lack of formal training in MSK ultrasound for both residents and fellows, leaving few musculoskeletal radiologists with specific expertise compared to their generally more robust experience in musculoskeletal MRI.
