Magnetic resonance imaging of sports-related injuries to the shoulder: impingement and rotator cuff.

MR imaging provides clinically useful information in detecting and characterizing sports-related pathology of the rotator cuff and other shoulder disorders in a non-invasive fashion. Complete and partial tears of the rotator cuff, as well as factors contributing to impingement, can be detected and characterized with MR imaging. The size and location of complete tears of the rotator cuff can be accurately determined with MR imaging.
