MRI provides excellent soft tissue contrast and allows for multiplanar imaging in
anatomic planes. Because of these advantages MRI has become the study of choice for
imaging of shoulder pathology. Some structures, such as the rotator cuff, humeral
head contour, and glenoid shape, are evaluated well with conventional MRI. When more
sensitive evaluation of the labrum, capsule, articular cartilage, and glenohumeral
ligaments is required or when a partial-thickness rotator cuff tear is suspected,
magnetic resonance (MR) arthrography with intra-articular contrast can be performed.
For MR arthrography contrast is injected directly into the glenohumeral joint. This
article reviews the appearances of normal anatomic structures in MRI of the shoulder
and disorders involving the rotator cuff and glenoid labrum.
