Imaging of the Rotator Cuff
Imaging plays a critical role in defining the extent of rotator cuff tears, which has important implications in clinical decision making, surgical planning, and prognosis. Multiple imaging modalities are available including magnetic resonance (MR) imaging, ultrasound, computed tomography (CT), and conventional radiographs, and each provides particular advantages. MR imaging and ultrasound are the most commonly used imaging modalities in the evaluation of rotator cuff pathology, as both offer detailed evaluation of rotator cuff tears with MR imaging providing a more comprehensive evaluation. CT provides information about the degree of atrophy and fatty infiltration of the cuff musculature and is useful for preoperative evaluation of the osseous integrity of the glenoid in rotator cuff tear arthropathy. Radiographs are a good initial evaluation indicating whether a massive cuff tear is likely and readily demonstrates the presence of cuff tear arthropathy.
