| 目的 探讨3.0T MRI对肩关节撞击综合征的诊断价值,并分析其影像征象及损伤机制。方法 回顾性分析30例肩撞击综合征患者的MRI表现及临床症状。结果 ①直接征象:30例MRI均显示冈上肌肌腱信号和形态的改变,其中6例冈上肌肌腱完全撕裂;13例冈上肌肌腱的部分撕裂;11例表现冈上肌肌腱表面的信号异常、混杂;②间接征象:9例肩峰下滑囊增厚、肩峰下-三角肌下囊积液及15例关节囊积液;③继发征象:5例关节盂唇撕脱,于关节造影时显示较好,5例冈上肌萎缩、2例三角肌萎缩、4例Bankart病变;④病因征象:本组患者肩峰形态分别为平直型(4/30)、弧形(7/30)、钩型(19/30);肩峰下通道(AHI)7例<5 mm,23例为5~10 mm之间。结论 高场强3.0T MRI能够有效显示肩撞击综合征的影像特征,有助于临床诊治。 ①直接征象:30例MRI均显示冈上肌肌腱信号和形态的改变,其中6例冈上肌肌腱完全撕裂;13例冈上肌肌腱的部分撕裂;11例表现冈上肌肌腱表面的信号异常、混杂;②间接征象:9例肩峰下滑囊增厚、肩峰下-三角肌下囊积液及15例关节囊积液;③继发征象:5例关节盂唇撕脱,于关节造影时显示较好,5例冈上肌萎缩、2例三角肌萎缩、4例Bankart病变;④病因征象:本组患者肩峰形态分别为平直型(4/30)、弧形(7/30)、钩型(19/30);肩峰下通道(AHI)7例<5 mm,23例为5~10 mm之间。结论 高场强3.0T MRI能够有效显示肩撞击综合征的影像特征,有助于临床诊治。 |

| Objective To explore the diagnostic value of 3.0T MRI in shoulder impingement syndrome (SIS), and to observe the imaging features and injuring mechanism of SIS. Methods Thirty patients of SIS underwent MRI, and the imaging findings and clinical symptoms were reviewed retrospectively. Results Theanatomical structures and abnormal changes of shoulder were excellently demonstrated with 3.0T MRI. ①Direct signs: Supraspinatus tendon illustrated signal and patterns changes in all 30 patients, while supraspinatus tendon full-thickness tears were detected in 6 patients; Partial-thickness tears were found in 13 patients, abnormal and mixed signals on the surface of the muscle tendon were found in 11 patients. ②Indirect signs: Subacromial bursa thickening, subacromial-deltoid sac fluid and the joint capsule fluid were signs of supraspinatus tendon tears. ③Secondary signs included joint labrum avulsion, the supraspinatus muscle atrophy and the deltoid muscle atrophy and Bankart Lesion. ④Etiological signs: Acromino were classified as flat, smoothly curved and hooked. AHI<5 mm(7/30) and between 5－10 mm (23/30). Conclusion 3.0T MR can effectively demonstrate imaging features in SIS and provide information to guide the protection and rehabilitation of shoulder function. |
