Aims: To compare Ultrasonography (USG) with Magnetic Resonance Imaging (MRI) in the evaluation of lesions causing impairment of mobility of the shoulder joint.
Method and Materials: This study was a cross-sectional observational study. Sonographic examination of the shoulder was done using a linear high-frequency probe (7.5-15 MHz) on a Siemens machine, and MRI evaluation was performed on a 3T Siemens Skyra machine. Data was analyzed using standard statistical methods, and results were compared with Arthroscopy where possible.According to the inclusion criteria, the patients of all age groups presenting with symptoms of shoulder pain or restricted movement referred from the department of orthopedics were studied.
Findings: Fifty patients were included in the study. Sensitivity and specificity of USG in comparison with MRI for diagnosing supraspinatus, subscapularis, infraspinatus, and long head of biceps tendon pathologies in our study were 95.4%, 100%, 66.6%, and 100%, 60% and 100%, 80%, and 100%, respectively. The sensitivity and specificity of USG for detecting AC joint arthropathy were 88.2% and 100%, respectively, in our study. The Sensitivity and specificity of USG were 82.7% and 100%, respectively, in detecting Subacromial Subdeltoid bursitis (SASD), which was similar to other studies in the literature.
Conclusion: This study revealed that USG has good sensitivity, specificity, and diagnostic accuracy in diagnosing rotator cuff tendon tears and tendinosis, as well as for the diagnosis of Acromioclavicular (AC) joint arthroplasty. Moreover, it is a non-invasive technique, readily available, and cost-effective. MRI is the best modality for diagnosing laborligamentous pathologies at the shoulder.
