MRI对肩腱袖撕裂的诊断及分级价值

Diagnosis and grading of MRI on rotator cuff tear

目的探讨MRI检查对肩腱袖撕裂的诊断及分级价值。方法回顾性分析36例肩腱袖撕裂MRI表现与文献及骨科手术对照。结果 36例肩腱袖撕裂,完全性撕裂11例,表现为肌腱连续性中断,肩腱袖肌腱回缩;部分性肩腱袖撕裂25例,表现为边界清晰不累及关节面或滑膜囊面的线样高信号,肩腱袖的滑膜面或关节囊面撕裂区可见积液。结论 MRI能准确判断肩腱袖撕裂范围及程度,是肩腱袖撕裂的最佳检查方法。

Objective To detect the diagnosis and grading of MRI on rotator cuff tear.Methods In retrospective study,detected 36 patients with rotator cuff tear by analyzing feature in MRI,compared with feature in operation.Results Among all the 36 patients,11 patients with complete laceration showed broken tendon and shrinking tendon of rotator cuff in MRI,25 patients with partial laceration showed line transect high signal characterized by clear margin and no-invasion to facies artiecularis or synovial capsule,meanwhile,effusion was seen in laceration area of facies artiecularis or synovial capsule.Conclusion MRI is able to accurately locate the range and grade of rotator cuff tear,it is a best approach to examine rotator cuff tear.
