スポーツ肩における関節唇損傷のMRアルトロ所見

抄録

Recently MR arthrography has been proposed as a possible replacement for evaluating shoulders. We investigated the findings of athletic shoulders. One hundred and four patients who had symptoms and sings suggesting shoulder instability underwest MR arthrography with intraarticular Gd-DTPA. Spin echo T1-weighted images were obtained in the axial and oblique coronal planes. Surgical or arthroscopic findings of the glenoid labra were available for 41 patients. Anterior labral tears were diagnosed in 35 out of the 41 by MR arthrography. Anterior labral tears were surgically confirmed in 34of the 35, but not in the other one. Superior labral tears were diagnosed in 8 out of the 41 by MR arthrography. Anterior labral tears were surgically confirmed in 7 of the 8 but not in the other one. We believe MR arthrography is useful in evaluating athletic shoulders, especially indiagnosing superior labral tears.
