Abstract: Objective To evaluate the value of endometrial volume measurement and 3-dimensional power Doppler imaging(3D-PDI) in the differentiation between endometrial polyps and endometrial hyperplasia.Methods One hundred and fifty-six women who diagnosed as thick and inhomogeneous endometrium or hyperechogenic focal intrauterine structures by 2D ultrasound were enrolled,including 50 patients with endometrial polyps in the proliferative phase,51 cases with hyperplasia and 55 cases with normal histology or others.All were scheduled for hysteroscopy,dilatation and curettage,and the ultrasound was performed within 24 hours before the procedure. Endometrial volume, vascularity index (VI), flow index (FI) and vascularity flow index (VFI) were measured. These parameters were compared between endometrial polyps group and endometrial hyperplasia group.Results These parameters (endometrial volume,VI,FI and VFI) were all considered statistically significant between two groups.Conclusions Endometrial volume and 3D-PDI are good diagnostic tools in the differentiation between endometrial polyps and endometrial hyperplasia.
