MRI定量参数对肩峰下撞击综合征的诊断值观察

Study on MRI Quantitative Parameters in the Diagnosis of Subacromial Impingement Syndrome

目的观察磁共振成像(MRI)定量参数对肩峰下撞击综合征(SIS)的诊断价值。方法选取2018年5月~2021年6月我院收治的肩峰下撞击综合征患者93例为研究组,选取同期健康志愿者57例为对照组,所有研究对象均采用MRI检查,比较两组的肩关节功能评分及MRI定量参数水平。结果研究组肩峰指数、肩锁关节骨赘高度均高于对照组,差异有统计学意义(P<0.05);最短肩肱间距小于对照组,肩关节功能评分低于对照组,差异有统计学意义(P<0.05);ROC曲线结果显示肩峰指数、肩锁关节骨赘高度与肩关节功能评分呈负相关,最短肩肱间距与肩关节功能评分呈正相关。应用各MRI定量参数联合诊断SIS的AUC为0.758、0.885、0.906。结论MRI检查结果可清晰显示SIS患者肩关节病理变化,其定量参数具有较高诊断价值。

Objective To observe the value of MRI quantitative parameters in the diagnosis of subacromial impingement syndrome(SIS).Methods In the study,93 patients with SIS were selected as the test group who had been admitted and treated in Bazhong Central Hospital from May 2018 to June 2021,and 57 healthy volunteers were selected as the control group.All of them underwent MRI examination.The shoulder joint function score(Constant-Murley),and MRI acquisition parameters were compared between the two groups.Results Compared with the control group,the acromion index and the height of acromioclavicular joint osteophytes were significantly higher.Meanwhile,the shoulder-brachial distance and the Constant score was significantly lower(P<0.05).The AUC values were 0.758 for acromion index,0.885 for acromioclavicular joint osteophytes,and 0.906 for shoulder-brachial distance,respectively.Conclusions MRI quantitative parameters are of high value in the diagnosis of SIS for displaying the pathological of shoulder joint clearly.
