内容紹介
スポーツによる肩関節の障害で頻度の高い肩関節脱臼、腱板損傷、上方関節唇(SLAP)損傷の画像診断について概説する。肩関節脱臼は関節唇の評価にMR Arthrography(MRA)、骨の評価には三次元CT画像が有用である。腱板損傷の超音波、MRI検査は付着部を中心に描出させるのが重要である。SLAP損傷はMRAが有用であるが正常変異との鑑別が重要である。
The shoulder dislocation, rotator cuff tear, and Superior Labrum Anterior and Posterior (SLAP) lesion are common diseases in the sports injury. MR Arthrography and three dimension CT are effective to evaluate the labrum and glenoid articular surface for shoulder dislocation, respectively. It is important that anatomic attachment of rotator cuff should be focused on ultrasound and MRI to evaluate rotator cuff tear. The normal variant should considered for correct diagnosis of SLAP lesion on MR Arthrography.
