Background: Magnetic Resonance (MR) arthrogram is the preferred diagnostic imaging study for detecting glenoid labral tears. Despite this, there is still discrepancy between MR arthrogram and arthroscopy, the diagnostic gold standard. We aim to identify areas of discordance between imaging findings and surgical findings to aid radiologists in a more accurate diagnosis of glenoid labral tears. Methods: A retrospective chart review was conducted at our institution on a population that underwent an MR arthrogram and then underwent shoulder arthroscopy within six months. Factors such as patient demographics, location of labral tear, and radiologist and surgeon experience were collected. Results: Analysis revealed a labral tear discrepancy rate of 14% and a labral tear location discrepancy rate of 39.. Read More»
