Background: The study aimed to evaluate of the role of high-resolution ultrasound and magnetic resonance imaging in patients with shoulder pain.
Material/Methods: This prospective study included 50 patients referred for ultrasound and MRI because of shoulder pain. All patients were examined clinically, followed by radiography of the affected shoulder. High-resolution ultrasound examination of the involved shoulder was performed together with an examination of the contralateral normal shoulder, followed by MRI of the symptomatic shoulder in all 50 patients.
Results: In the present study, the majority of patients were in age group 56–65 years, 56% were males and 44% were females (of a total of 50 patients). A total of 40 patients were diagnosed as having rotator cuff tears on ultrasound (USG) and MRI. USG showed complete-thickness tears in 25 patients and partial-thickness tears in 15 patients. MRI detected 28 complete- and 12 partial-thickness tears of the rotator cuff. In the diagnosis of rotator cuff tears, the strength of agreement between ultrasound and magnetic resonance imaging was good (kappa coefficient=0.79).
Conclusions: Ultrasonography of the shoulder shows promising results in the diagnosis of rotator cuff tears and in differentiating partial from complete tears. A wide availability, cost effectiveness and better tolerability of ultrasonography make it a modality of first choice for evaluating rotator cuff tears.
