Objective: The purpose of this article is to describe the normal and abnormal appearances of the tendons most easily and commonly assessed with sonography.
Conclusion: Sonography is important in musculoskeletal imaging, and its accuracy is at least equivalent to that of MRI for imaging tendon abnormalities. Although operator dependence is an often quoted disadvantage of sonography, most experienced musculoskeletal radiologists with a sound foundation in anatomy can rapidly master the technique and perform effective evaluations of normal and abnormal tendons.
