【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。
[Abstract]:Objective to investigate the effect of 3. 0T Mr hip arthrography (MRAA). Methods the MRA data of 74 patients with hip diseases were analyzed retrospectively. The results of arthroscopy were taken as the golden standard. To evaluate the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 3.0T MRA in the diagnosis of acetabular anterior lip and upper lip tears. The difference of MRA in the diagnosis of acetabular anterior lip and upper lip tear was compared. Results 61 anterior lip tears were confirmed by arthroscopy in 75 of 74 patients. The sensitivity, specificity and positive predictive value of 29 upper lip tears (physician 1 and physician 2) were detected by MRA. The negative predictive value and the accuracy rate were 90.16 / 55 / 61) and 91.80 / 56 / 68.57 / 11 / 14 and 85.71 / 12 / 14, respectively. 94.83and 96.555.56 / 58 / 64.71) and 70.5912 / 17). The sensitivity, specificity and positive predictive value of the diagnosis of upper lip tear were 88.00% 66 / 75) and 90.67%. The negative predictive value and accuracy were 89.66 / 29) and 93.10 / 27 / 29 / 91.30 / 42 / 46 and 95.6565 / 44 / 46, respectively. 86.67, 26 / 30) and 93.10 / 29, 93.33 / 45) and 95.65 / 44 / 46). 90.67% 68 / 75) and 94.67% 75.2 physicians were consistent in the diagnosis of acetabular anterior lip and upper lip tears. The Kappa values were 0.924 and 0.916, respectively. The negative predictive value of MRA in the diagnosis of acetabular upper lip tear was higher than that of the anterior lip. The difference was statistically significant (P < 0.01), but sensitivity and specificity. There was no significant difference in positive predictive value and accurate rate (P < 0.05). Conclusion 3.0T MRA is a reliable imaging method for the diagnosis of acetabular lip tear.
