ABSTRACT
Objective To compare the diagnostic value of transvaginal ultrasound(TVS)and thin-section oblique axial T2WI 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 T2WI 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 T2WI for diagnosing left and right USL-DIE were 0.721 vs 0.842 and 0.640 vs 0.901,respectively.Thin-section oblique axial T2WI 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 T2WI outperformed TVS in terms of diagnostic value for USL-DIE,providing valuable imaging support for accurate clinical diagnosis.
