Rotator cuff pathology is one of the most common causes of shoulder pain and dysfunction. In addition to history and physical examination, evaluation of a patient with shoulder pain often involves assessment of the rotator cuff with a diagnostic test such as high-resolution ultrasonography or MRI. High resolution ultrasound is non-invasive, less expensive and non-ionizing modality with good sensitivity in detecting rotator cuff disorders. It can be used as a focused examination providing rapid and real-time diagnosis. MRI is the gold standard for assessment of soft tissue structures around the shoulder joint. MRI is an excellent modality because of its multiplanar capability and high soft tissue contrast. Ultrasonography has comparable accuracy with MRI for assessment of rotator cuff disorders, and low cost of ultrasound makes it the most cost-effective screening method for rotator cuff disorders. 40 patients who presented with shoulder joint pain, restriction of movements or clinically suspected rotator cuff disorders, referred to Department of Radiodiagnosis. MRIhas a high sensitivity, specificity and accuracy for identifying rotator cuff disorders, particularly partial and full thickness tears than tendinosis. Supraspinatous tendon is the most commonly affected tendon, followed by the subscapularis and infraspinatous. Teres minor was not affected in any of the patients. Tears of the rotator cuff tendons are commonly associated with fluid in SA-SD and SC burase, USG had low sensitivity but high specificity for SA-SD bursitis, SC bursitis and acromio-clavicular joint pathologies.
