摘　　要：目的探讨磁共振成像(MRI)在肩关节周围炎(肩周炎)的病情评价中的应用作用。方法 2012年12月到2016年11月,选择在我院诊治的肩周炎患者78例作为肩周炎组,同期选择正常成人78例作为对照组,两组都进行MRI诊断,记录影像学特征,判定诊断价值。结果两组入选者的MRI质量都为优;在对照组MRI热成像表现为肩袖、滑膜囊、肌腱等结构清晰,观察组78例患者表现为冈上肌腱变性50例,三角肌下滑囊积液29例,冈下肌肌腱变性22例,盂肱关节腔积液16例,肩胛下肌滑囊积液14例,肱二头肌肌腱变性10例。肩周炎组的冈上和冈下肌腱以及肌筋膜厚度都明显大于对照组,对比差异有统计学意义(P<0.05)以肩关节镜检查结果为金标准,MRI确诊为阳性80例,阴性76例,为此MRI热成像诊断在肩周炎的灵敏度、特异度分别为100.0%、97.4%。结论 MRI在肩关节周围炎患者的应用具有很好的影像学特征,通过冈上肌腱、冈下肌腱和肌筋膜厚度的测定能有效反映病情状况,诊断效果比较高,有很好的应用价值。Objective To investigate the application wllues of magnetic resonance imaging （MRI） in evaluating the condition of scapulohumeral periarthritis. Methods From December 2012 to November 2016, 78 cases of our hospital in patients with scapulohumeral periarthritis as scapulohtuneral periarthritis group, and the normal adult 78 cases were selected as the control group at the same period, two groups were given MRI diagnosis, recorded imaging characteristics and imaging results, and were given the diagnostic value determination. Results Two groups of selected MRI quality were excellent： In the control group on MRI thermal imaging performance were more for the rotator cuff, synovial bursa and tendon structure clear, The observe group（78 cases） were showed supraspinatus tendon degeneration in 50 cases, subdeltoid bursa effusion in 29 cases, infraspinatus tendon degeneration in 22 cases, glenohumeral joint effusion in 16 cases, subscapularis muscle sliding bursa effusion in 14 cases, the biceps tendon degeneration in 10 cases. The the supraspinatus tendon, infraspinatus tendon and muscle fascia thickness in the scapnlohumeral periarthritis group were significantly higher than the control group, the difference were statistical significance（P〈0.05）. The shoulder arthroscopy results were as the gold standard, MRI thermal imaging diagnosis were positive in 80 cases, 76 cases were negative. Therefore MRI thermal imabfing diagnosis of scapulohumeral periarthritis sensitivity and specificity were 100.0% and 97.4%. Conclusion MRI has good image features in the application of scapulohumeral periarthritis, the snpraspinatus tendon, infraspinatus tendon and muscle fascia thickness measnrement can effectively reflect the condition, its diagnosis effects is relatively high that has rery good application values.
