Imaging of the rotator cuff and biceps tendon

Several different imaging techniques are available for evaluating the rotator cuff and biceps tendon. The common disorders of impingement, rotator cuff tears and biceps tendonitis are discussed along with the role which the various imaging modalities can play in establishing their diagnosis. Plain radiographs can be helpful particularly with a history of trauma but give limited information on the soft tissues. Ultrasound is a useful and inexpensive means of assessing the rotator cuff and biceps tendon but has a number of limitations and varying reports on its accuracy. Computed tomography (CT) is most helpful in the evaluation of shoulder trauma but gives limited information on the soft tissues. Magnetic resonance imaging (MRI) is an accurate imaging modality for evaluating the rotator cuff and biceps tendon, allowing visualisation of the soft tissues and the adjacent bony structures.
