Key result
Three-dimensional MRI of the shoulder provides accurate evaluation of glenoid bone loss and rotator cuff tears, offering potential advantages over 2D MRI and 3D CT with clinically feasible scan times.
Why the study?
Addition of 3D acquisitions with 3D reconstructions has become clinically feasible and improved understanding of shoulder pathologies, warranting a review of techniques and clinical applications.
3D MRI of the shoulder is a feasible and accurate imaging modality that can improve the evaluation of glenoid bone loss and rotator cuff pathology.

May aid glenoid and cuff assessment but should not change practice; leaves open prospective validation against standard imaging.
Magnetic resonance imaging provides a comprehensive evaluation of the shoulder including the rotator cuff muscles and tendons, glenoid labrum, long head biceps tendon, and glenohumeral and acromioclavicular joint articulations. Most institutions use two-dimensional sequences acquired in all three imaging planes to accurately evaluate the many important structures of the shoulder. Recently, the addition of three-dimensional (3D) acquisitions with 3D reconstructions has become clinically feasible and helped improve our understanding of several important pathologic conditions, allowing us to provide added value for referring clinicians. This article briefly describes techniques used in 3D imaging of the shoulder and discusses applications of these techniques including measuring glenoid bone loss in anterior glenohumeral instability. We also review the literature on routine 3D imaging for the evaluation of common shoulder abnormalities as 3D imaging will likely become more common as imaging software continues to improve.

Daniels et al. (2021) conducted a review in Shoulder pathology (glenohumeral instability, rotator cuff tears, labral tears). 3D MRI vs. 2D MRI and 3D CT was evaluated. Three-dimensional MRI of the shoulder provides accurate evaluation of glenoid bone loss and rotator cuff tears, offering potential advantages over 2D MRI and 3D CT with clinically feasible scan times.
