Value of three-dimensional transvaginal ultrasound in diagnosis of uterine cavity lesions / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the diagnostic value of three dimensional transvaginal sonograpy( 3D TVS) for uterine cavity lesions.Methods Two dimensional transvaginal sonography(2D TVS) and 3D TVS were performed on 46 patients with irregular vaginal bleeding.The diagnosis were compared with the results of pathology and hysteroscopy.Results Of 46 patients,16 cases were diagnosed as endometrial hyperplasia,12 cases as endometrial polyp,9 cases as submucous myoma,3 cases as endometrial cancer, and the remaining 6 cases as normal secretive phase.To endometrial hyperplasia,the specificity,sensitivity,accuracy of 2D TVS and 3D TVS was 66.7% , 93.7% , 76.1% and 90.0% ,100%, 93.5% respectively.To endometrial polyp,the specificity,sensitivity,accuracy of 2D TVS and 3D TVS was 88.2% , 58.3% , 80.4% and 100%, 83.3% , 95.7% respectively.Conclusions 3D TVS improves the diagnosis of uterine cavity lesions,3D TVS combined with 2D TVS is the first choice for uterine cavity lesions.
