[Purpose] Magnetic Resonance Imaging (MRI) has become widely used for the diagnosis of a rotator cuff tear of the shoulder. The preoperative MRI findings of the rotator cuff tear and intraoperative findings were examined.<BR>[Materials and methods] The subjects were 42 patients with a rotator cuff tear of the shoulder aged 42-81 years (mean,62.3 years). The apparatus used was an MRT-200FX,1.5 Tesla (Toshiba).<BR>[Results] In five of the eighteen patients with the massive and global rotator cuff tear showing clearly high signal intensity on the supraspinatus muscle belly in the T1-and T2-weighted images compared to the trapezius muscle belly, pulling by McLaughlin procedure could not be performed during surgery. The persistent tear of the rotator cuff causes fibrosis and fatty degeneration in the supraspinatus muscle with myostatic contracture, resulting in a high signal intensity on MRI.<BR>[Discussion] MRI of a rotator cuff tear of the shoulder can be used fo r not only the identification of the rupture site and area, but the determination of operative methods by examination of changes in the signal intensity of the supraspinatus muscle belly.
