摘要目的 探讨磁共振肩关节造影技术在临床肩关节损伤诊断中的应用价值.方法 选取2015 年1 月至2018年12月香港大学深圳医院收治的15 例经肩关节镜检查证实的肩关节损伤患者为研究对象,回顾性分析患者术前常规MRI和MR肩关节造影(MRA)的临床资料.结果 关节镜结果显示15 例肩关节损伤患者中,肩袖全层撕裂2例、肩袖部分撕裂10例、肩袖撕裂并发盂唇损伤例3 例.MRA对应诊断结果为:2 例、10例和3 例,与关节镜结果一致.常规MRI诊断结果:肩袖全层撕裂1 例(正确诊断率93.0％,漏诊率为50.0％,误诊率为0),肩袖部分撕裂12例(正确诊断率86.7％,漏诊率为0,误诊率为40.0％),肩袖撕裂并发盂唇损伤例2 例(正确诊断率93.3％,漏诊率为33.3％,误诊率为0),其中有2 例被误诊为肩袖部分撕裂,MRA和关节镜显示为肩袖全层撕裂1 例和肩袖撕裂并发盂唇损伤例1 例.结论 MR肩关节造影较常规MRI检查能提高肩关节损伤的诊断准确性,具有临床应用价值.

abstractsObjective To explore the value of MRI in the diagnosis of shoulder joint injury.Methods Fifteen patients with shoulder joint injury confirmed by shoulder arthroscopy admitted to Shenzhen Hospital of Hong Kong University from January 2015 to December 2018 were selected,the clinical data of preoperative routine MRI and Mr shoulder arthrography(MRA)were analyzed retrospectively.Results Arthroscopic results showed that in 15 patients with shoulder joint injury,there were 2 full-thickness rotator cuff tears,10 partial rotator cuff tears and 3 glenoid lip injuries.The results of MRA were 2 cases,10 cases and 3 cases,which were consistent with arthroscopic results.Routine MRI diagnosis results:1 case of rotator cuff full-thickness tear(correct diagnosis rate was 93.3％,missed diagnosis rate was 50.0％,misdiagnosis rate was 0),12 cases of rotator cuff partial tear(correct diagnosis rate was 86.7％,missed diagnosis rate was 0,misdiagnosis rate was 40.0％),2 cases of rotator cuff tear complicated with glenoid lip injury(positive diagnosis rate was 93.3％,missed diagnosis rate 33.3％,misdiagnosis rate was 0),of which 2 cases were misdiagnosed as rotator cuff partial tear MRA and arthroscopy showed 1 case of full-thickness rotator cuff tear and 1 case of glenoid lip injury caused by rotator cuff tear.Conclusions Compared with conventional MRI,MR arthrography can improve the diagnosis accuracy of shoulder joint injury and has clinical application value.
