Imaging Modalities in Shoulder Arthritis

This article aims to provide an extensive review of all relevant imaging modalities utilized in the evaluation and treatment of glenohumeral (GH) arthritis. The most common imaging study obtained is radiography to provide baseline evaluation of the GH joint. Computed tomography scans provide further evaluation of the osseous anatomy of the shoulder and anatomic variation. MRI enables detailed assessment of soft tissue, notably the rotator cuff musculature and tendons. Other imaging modalities, such as ultrasound and nuclear medicine studies, are also discussed. Each imaging modality described can be used in pre-operative planning and post-operative monitoring of patient outcomes.
