Abstract：ObjectiveTo compare the value of transvaginal two-dimensional and three-dimensional ultrasonography in the diagnosis of intrauterine lesions,to provide reference for clinical diagnosis.MethodsAltogether 182 cases of pathologically confirmed patients who were diagnosed as intrauterine lesions from January 2012 to December 2014 in our hospital were divided into two groups,90 cases who accepted preoperative transvaginal three-dimensional ultrasound examinations were selected as the observation group,92 cases who accepted preoperative transvaginal two-dimensional ultrasound examinations at the same period of time were selected as the control group.The specificity,sensitivity,accuracy,positive diagnosis rate and negative diagnostic rate of the two groups were compared.ResultsThe sensitivity,specificity,accuracy,positive predictive value and negative predictive value of the observation group in the diagnosis of endometrial hyperplasia and endometrial polyps,uterine fibroids mucosa by using three-dimensional ultrasound examinations was higher than those of the control group,with significant difference(P＜0.05).As for the diagnosis of endometrial cancer,the sensitivity and accuracy of the observation group was higher than those of the control group,with significant difference(P＜0.05),there was no significant difference in the the specificity,positive predictive value and negative predictive valuebetweenthetwogroups(P＞0.05).ConclusionTransvaginalthree-dimensionalultrasoundcandisplaycoronalsectionwith higher detection rate of intrauterine diseases than two-dimensional ultrasound,which has great clinical significance.
