摘要
目的探讨MRI在肩关节损伤诊断中的应用价值。方法收集我院86肩关节损伤患者MRI影像学资料并进行分析。结果 MRI诊断肩袖病变、长头腱、肩关节不稳、SLAP损伤检出率均依次为89.5%(34/38)、85.2%(22/27)、80.0%(8/10)、63.7%(7/11),其中诊断肩袖病变的灵敏度、阳性预测值、准确率依次为93.9%、96.9%、91.8%,长头腱依次为91.3%、91.3%、85.2%,均高于肩关节不稳85.7%、75.0%、70.0%,及SLAP损伤75.0%、85.7%、72.7%;对肩袖部分撕裂者,其MRI上可观察肌腱内因血肿或出血形成的线样高信号;肱二头长头肌腱损伤者表现为肌腱增厚且信号增高,软骨下骨质硬化和关节面下囊呈低信号。结论MRI对肩关节损伤病变具有较高的检出率,能详细显示肩关节解剖结构,对软组织损伤具有较高的灵敏度、准确率。
Objective To explore the value of MRI in the diagnosis of shoulder joint injury.Methods The MRI data of 86 patients with shoulder joint injuries were collected and analyzed.Results The MRI detection rates of rotator cuff lesions,long tendon,shoulder instability and SLAP injury were 89.5%(34/38),85.2%(22/27),80%(8/10)and 63.7%(7/11),respectively.The sensitivity,positive predictive value and accuracy rate in the diagnosis of rotator cuff lesions were 93.9%,96.9%and 91.8%,respectively,in the diagnosis of long tendon were 91.3%,91.3%and 85.2%,respectively,in the diagnosis of shoulder instability were 85.7%,75.0%and 70.0%,respectively,and in the diagnosis of SLAP injury were 75.0%,85.7%and 72.7%,respectively.For patients with partial rotator cuff tears,high signal due to hematoma or hemorrhage in tendon can be observed on the MRI.Patients with long tendon of biceps muscle injuries showed tendon thickened and increased signal,subchondral osteosclerosis and subarticular capsule showing low signal.Conclusion MRI has a high detection rate for shoulder lesions.It can show the anatomical structure of shoulder joint in detail,with high sensitivity and accuracy in the diagnosis of soft tissue injury.
