目的：目的：探讨髋关节MR对髋臼唇撕裂的诊断价值，并进一步比较常规MR与MR关节造影对髋臼唇撕裂的诊断价值。其中34例同时接受常规MR和MR关节造影检查，56例仅接受常规MR检查。结果：90例患者中，59例经髋关节镜检查证实有唇恐惧，31例无唇恐惧。常规MR检查诊断唇突畸形的敏感性、特异性、阳性预测值（PPV）和阴性预测值（NPV）分别为61.0%、77.4%、83.7%和51.1%放射科医师A、B、B的诊断正确率分别为66.1%、74.2%、82.9%和53.4%，两人诊断的一致性较好（K=0.645）。MR关节造影评估髋臼唇撕裂的敏感性、特异性、PPV和NPV分别为90.5%、84.6%、90.5%和84.6%（放射科医师A）和95.2%、84.6%、90.9%和91.7%（放射科医师B），两名观察者之间具有极好的一致性（K=0.810）。MR髋关节造影诊断髋臼唇侧撕裂的敏感性和NPV均显著高于常规MR（P均< 0.05）。结论：髋关节MR髋关节造影是诊断髋臼唇侧撕裂的可靠方法，其诊断性能优于3.0T常规MR，且具有上级诊断价值。(C)2014爱思唯尔爱尔兰有限公司版权所有。
Objective: To evaluate the value of hip MR for diagnosing acetabular labrum tears, and to further compare the diagnostic performances of conventional MR with MR arthrography in acetabular labrum tears.Methods: 90 patients undergoing both hip MR examination and subsequent hip arthroscopy were retrospectively evaluated. Of these patients, 34 accepted both conventional MR and MR arthrography; while the other 56 only underwent conventional MR examination. All hip MR images were independently reviewed by two radiologists, and further compared with the results of hip arihroscopy.Results: 59 of 90 patients were confirmed with acctabular labial fears by hip arthroscopy and 31 without fears. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of conventional MR for evaluating the acctabular labral fears were 61.0%, 774%, 83.7% and 51.1% (radiologist A), and 66.1%, 74.2%, 82.9% and 53.4% (radiologist B), respectively, with good consistency between the two observers (K=0.645). The sensitivity, specificity, PPV and NPV of MR arthrography for assessing the acetabular labial tears were 90.5%, 84.6%, 90.5% and 84.6% (radiologist A), and 95.2%, 84.6%, 90.9% and 91.7% (radiologist B), respectively, with excellent good consistency between the two observers (K=0.810). The sensitivity and NPV of MR arthrography for diagnosing the acetabular labial tears were significantly higher than those of conventional MR (both P< 0.05).Conclusion: Hip MR arthrography is a reliable evaluation modality for diagnosing the acetabular labial tears, and its diagnostic performance is superior to that of conventional MR at 3.0T.
