Abstract
BACKGROUND/AIMS: We compared the accuracy of US to 3 T Tesla MRI for the detection of rotator cuff and long biceps tendon pathologies before joint replacement. METHODS: 45 patients were prospectively included. RESULTS: For the supraspinatus tendon, the accuracy of US when using MRI as reference was 91.1%. For the infraspinatus tendon, the accuracy with MRI as reference was 84.4%. The subscapularis tendon was consistently assessed by US and MRI in 35/45 patients (accuracy 77.8%). For the long biceps tendon the accuracy was 86.7%. CONCLUSION: US detection of rotator cuff and biceps tendon integrity is comparable to MRI and should be preferred in revision cases.
