The rotator interval is an anatomically complex region of the shoulder joint that is difficult to evaluate on clinical examination and by imaging. Abnormalities of its components may contribute to instability, shoulder stiffness, and pain and are challenging to diagnose and treat. This article gives an overview of the anatomy, MR anatomy, and normal variants of the rotator interval, together with basic technical aspects of MR imaging of this area. Pathologic conditions of the rotator interval capsule, the long head of biceps tendon, and the pulley system are reviewed and illustrated with several clinical examples.
