单侧髋3.0 T MRI在髋关节撞击综合征患者中的应用价值

目的探讨单侧髋3.0 T MRI在髋关节撞击综合征(femoroacetabular impingement,FAI)中盂唇损伤的诊断价值。材料与方法回顾性分析本院2015年1月至2017年6月共60例经关节镜证实为FAI的患者术前MRI图像资料,并与关节镜进行比较。结果 MRI对髋臼前上唇损伤的灵敏度、特异度、准确率、阳性预测值、阴性预测值分别为78.9%、100%、80%、100%、20%。对于唇旁囊肿、股骨头囊肿、圆韧带损伤、股骨颈疝窝诊断的符合率均为100%,而对于软骨损伤诊断的符合率为8.3%。结论单侧髋3.0 T MRI对FAI患者髋臼唇损伤有较高的诊断价值。

Unilateral hip 3.0 T MRI application in femoroacetabular impingement

Objective: The purpose of our study is to evaluate the value of 3.0 T MRI for the diagnosis of acetabular labrum injury in the patients with femoroacetabular impingement (FAI). Materials and Methods: From January 2015 to June 2017 imaging features of 60 patients with FAI confirmed by arthroscopy were analyzed retrospectively, and compared with the results of arthroscopy. Results: The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of MRI diagnosis of acetabular labrum injury were 78.9％, 100％, 80％ , 100％ and 20％respectively. The coincidence of MRI diagnosis of paralabral cyst, femoral head cyst, round ligament injury, herniation pit were 100％, and the coincidence of MRI diagnosis of cartilage injury was 8.3％. Conclusions: Unilateral hip 3.0 T MRI is of great value in the diagnosis of acetabular labrum injury in FAI patients.
