摘　　要：目的比较经阴道超声(TVS)和薄层斜轴T_(2)WI对子宫骶韧带(USL)深部浸润型子宫内膜异位症(DIE)的诊断价值。方法回顾性分析74例USL-DIE患者术前的TVS及MRI图像,以病理结果为标准,使用受试者工作特征(ROC)曲线评估TVS与薄层斜轴T_(2)WI对USL-DIE的诊断效能,并计算曲线下面积(AUC)、敏感度、特异度、准确度、阳性预测值(PPV)和阴性预测值(NPV)。采用McNemar双尾检验分析2种检查方法对USL-DIE诊断准确率的差异。结果TVS和薄层斜轴T_(2)WI诊断左、右侧USL-DIE的AUC分别为0.721 vs 0.842、0.640 vs 0.901,薄层斜轴T_(2)WI诊断USL-DIE的敏感度、准确度、PPV及NPV均高于TVS,且诊断准确度有统计学差异(P左=0.026,χ^(2)=4.966;P右<0.001,χ^(2)=16.531)。结论与TVS相比,薄层斜轴T_(2)WI对USL-DIE的诊断价值更高,有望为临床的准确诊断提供有价值的影像学支持。Objective To compare the diagnostic value of transvaginal ultrasound(TVS)and thin-section oblique axial T_(2)WI in deep infiltrating endometriosis(DIE)of uterosacral ligaments(USL).Methods Retrospective analysis was conducted on preoperative TVS and MRI images from 74 patients with USL-DIE.The diagnostic efficacy of TVS and thin-section oblique axial T_(2)WI for USL-DIE was evaluated using receiver operating characteristic(ROC)curve based on pathological findings,and area under the curve(AUC),sensitivity,specificity,accuracy,positive predictive value(PPV)and negative predictive value(NPV)were further calculated.The McNemar two-tailed test was used to analyze the difference in diagnostic accuracy between the two methods for USL-DIE.Results The AUCs of TVS and thin-section oblique axial T_(2)WI for diagnosing left and right USL-DIE were 0.721 vs 0.842 and 0.640 vs 0.901,respectively.Thin-section oblique axial T_(2)WI demonstrated higher sensitivity,accuracy,PPV,and NPV compared to TVS in diagnosing USL-DIE.The diagnostic accuracy was found to be statistically different between the two methods(Pleft=0.026,χ2=4.966;Pright<0.001,χ2=16.531).Conclusion Thin-section oblique axial T_(2)WI outperformed TVS in terms of diagnostic value for USL-DIE,providing valuable imaging support for accurate clinical diagnosis.
