MRI和MR对肩关节前方盂唇损伤的关节造影诊断

MRI arthrography and MRI diagnosis of anterior shoulder labrum injury

目的 比较MRI和MR对肩关节前方盂唇损伤的关节造影诊断效果。方法 收集2013年3月~2016年3月本院收治的100例肩关节不稳和（或）脱位患者为研究对象,对30例经关节镜证实为肩关节前方盂唇损伤的患者和未经证实该症的70例患者,均行MRI和MR关节造影,观察两种影像学诊断方法应用于肩关节上盂唇损伤检查临床的灵敏度、特异度、约登指数及准确性,及两种影像学诊断方法应用于肩关节上盂唇损伤分型鉴别临床的符合率。结果 MR关节造影诊断肩关节前方盂唇损伤的特异度和准确性分别为98.6%和98.0%,显著优于MRI 90.0%和90.0%,两组比较差异有统计学意义（P=0.028,0.0172）;MRI诊断肩关节前方盂唇损伤分型符合率为76.6%,同MR关节造影90.0%比较,差异无统计学意义（P=0.921）。结论MR关节造影诊断肩关节前方盂唇损伤,特异性和准确性更高,值得推广应用。

Objective To compare the effect of MRI and MR for anterior shoulder labrum injury in the diagnosis arthrography. Methods 100 cases of shoulder instability and （or） dislocation of the patients cured in our hospital from March 2013 to March 2016 were gathered as the study objects, 30 patients with confirmed arthroscopic anterior shoulder labrum injury patients and unconfirmed 70 patients of the disease were all underwent MRI and MR arthrography. Clinical sensitivity, specificity, youden index and accuracy of two imaging diagnostic methods on the shoulder labrum injury check were observed and compared. And clinical compliance rates of two imaging diagnostic methods on the shoulder labrum injury classification were observed and compared. Results Specificity and accuracy of MR arthrography diagnosis of anterior shoulder labrum injury were 98.6% and 98.0%, which were significantly better than MRI with 90.0% and 90.0%. The differences between the two groups was statistically significant P=0.028, respectively and P=0.0172. Compliance rate of MRI diagnosis of anterior shoulder labrum injury was 76.6%, Compliance rates of MR diagnosis of anterior shoulder labrum injury was 90.0%. There was no statistical significance （P=0.921）. Conclusion Specificity and accuracy of MR arthrography diagnosis of anterior shoulder labrum damage were higher. It is worth popularizing and applying.
