MRI-Arthroscopy Correlation of the Rotator Cuff: A Case-based Review

With significant advancements over recent decades, magnetic resonance imaging (MRI) and shoulder arthroscopy are important complementary tools in guiding orthopedic surgeons to diagnosis, decision making, and treatment of rotator cuff pathology. The objective of this article is to review the basic principles and pearls of MRI-arthroscopy correlation of the rotator cuff through an overview of our approach to reading shoulder MRI followed by a case-based review of selected conditions. By understanding and comparing the subtleties of these modalities, radiologists and clinicians can better appreciate both the utility and limitations of MRI in predicting operative findings.
