Abstract:
Objective To evaluate the diagnostic value of MR arthrography for rotator cuff tear. Methods A prospective study was undertaken in 32 patients with shoulder diseases using MR arthrography. Abnormalities revealed on MR arthrography of the rotator cuff, the labrum, and the tendon of the long head of the biceps brachii muscle were recorded. The results of MR arthrography were compared with those of arthroscopy and surgery. Results Based on the results of arthroscopy and surgery, 32 patients comprised 14 complete rotator cuff tear, 6 partial rotator cuff tear, and 12 subjects without tear. For detecting rotator cuff tear, the sensitivity, specificity, and accuracy of MR arthrography were 100%, 100%, 100% respectively. For detecting complete rotator cuff tear, the sensitivity, specificity, and accuracy of MR arthrography were 100%, 94%, 97% respectively. Meanwhile, MR arthrography revealed all multi tendon tear and all abnormalities of the labrum and the tendon of the long head of the biceps brachii muscle before arthroscopy. Conclusion MR arthrography is an accurate and comprehensive method for evaluating rotator cuff tear.
