1. Recognize the high-resolution ultrasonography (US) appearance of normal and injured musculoskeletal (MSK) structures including bone surface, muscle, tendon and ligament. 2. Recognize the US findings of common artifacts in MSK US with B-mode gray-scale and Doppler imaging that can be mistaken for pathology and several artifacts that frequently accompany pathologic conditions. 3. Learn techniques that can help avoid or minimize artifacts in MSK US.  

1. MSK US Equipment and Technology 2. US findings of normal bone, muscle, tendon and ligament 3. US findings of injured bone, muscle, tendon and ligament 4. US artifacts with B-mode gray-scale imaging: side-lobe, beam-width, anisotropy, artifacts related to velocity errors (speed displacement and refraction), posterior acoustic shadowing, posterior acoustic enhancement/increased through transmission, posterior reverberation, and mirror image 5. US artifacts with Doppler imaging: transducer pressure, tissue strain, improper focus, motion, blooming, mirror image, background noise, aliasing, and twinkling 6. Techniques that can help avoid or minimize artifacts in MSK US.
