摘要: 目的 总结肩袖全层撕裂的MRI表现。 材料与方法 回顾性分析21例肩关节MR造影证实的肩袖全层撕裂的MR图像。 结果 21例肩袖全层撕裂均发生在冈上肌腱。在T2W序列上,6例(28.9%)表现为冈上肌腱断裂并断裂端的回缩;12例(57.1%)表现为冈上肌腱变薄或增粗并伴有贯穿冈上肌腱全层的高信号;1例(4.7%)表现为冈上肌腱增厚并未贯穿全层的下表面高信号;2例(9.3%)冈上肌腱的形态和信号未见异常。 结论 冈上肌腱的断裂并回缩以及冈上肌腱形态增粗或变细并伴有贯穿肌腱全层的异常高信号为全层撕裂的主要MRI表现。 Objective To describe the MR findings of the full-thickness tears of the rotator cuff. Materials and Methods MRI findings in 21 cases with complete rotator cuff tears, proved with MR arthrography, were retrospectively analyzed. Results All 21 tears involved the supraspinatus tendon. On T2WI , the signs of the tears were as follows: interrupted tendinous continuity and retraction of musculotendinous junction (6 shoulders, 28.9%), increased signal intensity covering the entire layer of the thickened or thinned tendon (12 shoulders, 57.1%), focal high signal involving only the inferior surface of the thickened supraspinatus tendon (1 shoulder, 4.7%), and normal tendinous appearance (2 shoulders, 9.3%). Conclusion The main MR findings of full-thickness tears of the rotator cuff are discontinuity and retraction of the supraspinatus tendon, and increased signal intensity extending through the entire layer of the thickened or thinned tendon.
