© 2020 American Institute of Ultrasound in MedicineThe frequency of musculoskeletal system ultrasonography (US) has increased over time. The most common reason for musculoskeletal US is the evaluation of tendons. The superficial location of tendons makes US the most suitable diagnostic tool, and US is generally the initial imaging modality for tendon disorders. The primary advantages of US are its low cost, easy accessibility, rapidity, repeatability, freedom from x-rays, and enabling of a dynamic inspection. In addition, Doppler US and elastography can be performed simultaneously with US. We aimed to demonstrate the US and elastographic findings of tendon disorders that we frequently encounter in different regions.
