Role Of High-Resolution Ultrasound In Evaluation Of Shoulder Impingement. A Comparative Study With MRI

Abstract

Background: Shoulder impingement is the most common cause of shoulder pain. High-resolution ultrasonography can be utilised to assess different pathological abnormalities encountered in cases of shoulder impingement. MRI, on the other hand, was the gold standard in our study.

Results: Twenty patients complained of shoulder pain and restricted shoulder movement. Grey scale ultrasonography and conventional MRI were used to examine all of the patients. Both modalities' outcomes were recorded and compared. The sensitivity of high-resolution ultrasonography in the identification of shoulder impingement and other disorders affecting the shoulder joint was found as follow: 80 % for rotator cuff tendinopathy, 78.8% and 100% for partial and full-thickness tears of rotator cuff, respectively, 100% for calcific tendinitis and 81.82% for acromiocalvicular osteo-arthritis.

Conclusion:  According to our findings, high resolution ultrasonography with dynamic real-time assessment should be employed more frequently as the first line imaging modality in the evaluation and assessment of various disorders causing shoulder impingement.
