摘　　要：目的探讨3.0T MR髋关节造影(MRA)在髋臼唇撕裂诊断中的价值。方法回顾性分析74例髋关节疾病患者的髋关节镜及术前髋关节MRA资料。以关节镜检查结果为金标准,评估3.0T MRA诊断髋臼前唇和上唇撕裂的敏感度、特异度、阳性预测值、阴性预测值和准确率,并比较MRA诊断髋臼前唇和上唇撕裂的差异。结果 74例患者的75个髋关节中,关节镜证实61处前唇撕裂,29处上唇撕裂。2名医师(医师1和医师2)采用MRA诊断髋臼前唇撕裂的敏感度、特异度、阳性预测值、阴性预测值和准确率分别为90.16%(55/61)和91.80%(56/61)、78.57%(11/14)和85.71%(12/14)、94.83%(55/58)和96.55%(56/58)、64.71%(11/17)和70.59%(12/17)、88.00%(66/75)和90.67%(68/75),诊断上唇撕裂的敏感度、特异度、阳性预测值、阴性预测值和准确率分别为89.66%(26/29)和93.10%(27/29)、91.30%(42/46)和95.65%(44/46)、86.67%(26/30)和93.10%(27/29)、93.33%(42/45)和95.65%(44/46)、90.67%(68/75)和94.67%(71/75)。2名医师诊断髋臼前唇和上唇撕裂的一致性好(Kappa值分别为0.924和0.916)。MRA诊断髋臼上唇撕裂的阴性预测值高于前唇,差异有统计学意义(P=0.01),而敏感度、特异度、阳性预测值和准确率的差异均无统计学意义(P均>0.05)。结论 3.0T髋关节MRA是诊断髋臼唇撕裂的可靠影像方法。Objective To explore the value of hip MR arthrography（MRA）in diagnosis of acetabular labral tears.Methods A total of 74 patients with hip diseases who underwent both hip MRA and subsequent hip arthroscopy were retrospectively reviewed.The sensitivity,specificity,positive predictive value（PPV）,negative predictive value（NPV）and accuracy of MRA in diagnosis of anterior and superior acetabular labral tears were calculated,using the results of arthroscopy as gold standard.The differences in diagnosis of anterior and superior acetabular labral tears by MRA were also evaluated.Results Of these 74 patients,61anterior and 29 superior acetabular labral tears were confirmed by hip arthroscopy.The sensitivity,specificity,PPV,NPV and accuracy of MRA for diagnosing anterior acetabular labral tears of radiologist 1and radiologist 2were 90.16%（55/61）and 91.80%（56/61）,78.57%（11/14）and 85.71%（12/14）,94.83%（55/58）and96.55%（56/58）,64.71%（11/17）and 70.59%（12/17）,88.00%（66/75）and 90.67%（68/75）,respectively.The sensitivity,specificity,PPV,NPV and accuracy of MRA for diagnosing superior acetabular labral tears of radiologist 1and radiologist 2were 89.66%（26/29）and 93.10%（27/29）,91.30%（42/46）and 95.65%（44/46）,86.67%（26/30）and93.10%（27/29）,93.33%（42/45）and 95.65%（44/46）,90.67%（68/75）and 94.67%（71/75,respectively.The Kappastatistics for diagnosing anterior and superior acetabular labral tears were 0.924 and 0.916 respectively,demonstrating agood interobserver agreement.The NPV of MRA in diagnosis of superior acetabular labral tears was significantly higher than that of anterior labral tears（P=0.01）,while no statistical significance was found in sensitivity,specificity,PPV and accuracy（all P〉0.05）.Conclusion 3.0Thip MRA is a reliable method in diagnosis of acetabular labral tears.
