[Echography of the musculo-tendinous system].

Ultrasonography is the preferred diagnostic tool for evaluation of musculo-tendinous pathology, especially for the diagnosis of long-tendon diseases (rotary cuff, Achille's and patellar tendon.). Pathology due to injury of the musculo-tendinous system benefits as well of sonography, for it allows a more accurate diagnosis and treatment decision. For soft tissue masses of the extremities, ultrasound is less accurate than CT and IRM, particularly for those arising close to the bony boundaries, and it provides less detailed anatomical information. However, US is accurate in determining the size of soft tissue masses.
