Background: Magnetic resonance (MR) provides detailed information for the depiction of shoulder lesions. It allows a unique anatomical and tissue characterization providing a detailed evaluation of the rotator cuff (RC) and the surrounding bones.Purpose: Our objective is to assess the diagnostic accuracy of MR in depiction of lesions encountered in shoulder impingement and rotator cuff (RC) degenerative lesions compared to shoulder arthroscopy.Patients and methods: This study included 28 patients with shoulder impingement for which conventional MR was done followed by arthroscopy. The results of MR were compared to the results of surgical repair.Results: MR was highly accurate in the diagnosis of full-thickness (FT) tears of the RC, showing 100% accuracy, 100% sensitivity, and 100% specificity. MR was capable of comprehensive evaluation of FT tears. MR had a high accuracy (96%) in the diagnosis of partial-thickness (PT) RC tears. It showed 100% specificity and 100% positive predictive value (PPV) with no false positive cases. MR revealed high specificity (100%) in the diagnosis of biceps abnormalities. It identified all the 20 negative cases that were confirmed surgically.Conclusion: Conventional MR plays an adequate role in evaluation of different lesions encountered in shoulder impingement and RC degenerative disorders
