Magnetic Resonance Imaging, Arthrography, And Ultrasound In Diagnosing Rotator Cuff Tears: An Evaluation Of Agreement, Andrea Solsona

Legacy ETDs

Eleven patients who had a clinical suspicion of a rotator cuff tear were referred for a magnetic resonance imaging exam, an arthrographic exam or both. Additionally, all patients received a diagnostic ultrasound exam. The results of the imaging studies were compared to surgical or clinical diagnosis. Arthrography had 100% positive predictive value (PPV), negative predictive value (NPV), accuracy, specificity, and sensitivity. Magnetic resonance imaging had 100% PPV, 60% NPV, 78% accuracy, 100% specificity, and 67% sensitivity. Ultrasound had 80% PPV, 50% NPV, 64% accuracy, 75% specificity, and 57% sensitivity. Based on these results, taking into consideration the national average costs …
