| Abstract | ||||
| Background: The advantage of ultrasound (US) and capability of dynamic evaluation can improve the accuracy of US diagnoses of shoulder pain, especially when the cause is not immediately apparent during a routine evaluation. The current research aimed to evaluate the role of dynamic ultrasound as a non-invasive modality in diagnosis of shoulder impingement syndrome in comparison to magnetic resonance imaging (MRI) findings. Methods: Thirty-six patients with a clinical diagnosis of subacromial impingement were involved in this cross-sectional study that conducted at Radiodiagnosis Department of Zagazig University Hospital. Static and dynamic ultrasonography were performed to all cases in addition to conventional MRI examination. Results: Our results revealed that ultrasound had 100% sensitivity and specificity in detecting supraspinatus tear when compared to conventional MRI. Also, ultrasound showed 100% sensitivity and 86.7% specificity in detection of calcification in supraspinatus muscle when compared to MRI. Ultrasound had 100% specificity and 80% sensitivity in detection of infraspinatus tendenopathic changes. Also, ultrasound had 100% specificity and 87.5% sensitivity in detection of tendenopathic changes in subscapularis tendon. Ultrasound shows 100% sensitivity and specificity in detecting biceps tenosynovitis and acromioclavicular joint osteoarthritis when compared to conventional MRI. A statistically significant reduction of the sub-acromial tunnel during active shoulder movement was found with mean difference 0.42 (P <0.001). Conclusion: For evaluating the shoulder impingement as well as the rotator cuff disorders, ultrasound was found to be comparable to MRI. | ||||
