(Purpose and method) Partial cuff tears have been diagnosed clinically with an arthrography and a subacromial bursography. The purpose of this study was to evaluate the diagnostic values of MRIs of this lesion. We compared the MRIs and the operative findings and assessed the tear size, the localization of the subacromial bursal and long bicepital lesions.59 shoulders of 57 patients with partial cuff tears were scanned on MRIs with a GE Signa Advantage 1.5 T.
(Results) In 56 bursal side tears, high signal cuff lesions were observed in all and their tear shapes were easily recognized on T2 weighted images. The other joint sides, intratendinous tears and high signal lesions were confirmed at their portions. We could also validate the subacromial effusion and long bicepital lesions in additional to partial cuff tear lesions.
(Conclusion) We concluded that MRIs have a significant diagnostic value. They demonstrated a variety of partial tears and additional pathological lesions.
