ABSTRACT
Objective To evaluate the value of three-dimensional power Doppler imaging(3D-PDI) in the discrimination between benign and malignant endometrium in women with postmenopausal bleeding. Methods Eighty-four women with post menopausal bleeding who examined by 3D-PDI were enrolled. All patients scheduled for pathological examination were divided into benign group (30 cases with endometrial polyps and 34 cases with hyperplasia) and malignant group (20 cases with endometrial carcinoma). Endometrial volume, vascularity index ( VI) , flow index ( FI) and vascularity flow index ( VFI) were measured. The diagnostic value of parameters derived from 3D-PDI was evaluated by using the receiver operating characteristic ( ROC) curve. Results Differences of these parameters (VI, FI and VFI) were considered statistically significant between two groups, the parameters of endometrial volume had no significant differences between two groups; the area under ROC curve(AUC) of the meaningful data were 0.976,0.888 and 0.894 respectively. Among these parameters, VI had the highest diagnostic value for discriminating between benign and malignant endometrium, the cut-off value of which was 2. 97 with a sensitivity of 95% and a specificity of 86%. Conclusions 3D-PDI is a good diagnostic tools in the discriminations between benign and malignant endometrium in women with postmenopausal bleeding.
