To evaluate the diagnostic efficiency of two dimensional 2d and three dimensional 3d transvaginal ultrasonography power doppler angiography pda and gel infusion sonography gis at offline analysis for recognition of malignant endometrium compared with real time evaluation during scanning and to determine optimal image parameters . To assess the feasibility of imaging low velocity blood flow in adnexal masses by transvaginal three dimensional power doppler sonography to analyze three dimensional power doppler sonography data sets with a new computer assisted method and to test the reproducibility of the technique methods. Three dimensional power doppler ultrasound 3d pdu has emerged in the last decade as a new method for assessing the vascularity of solid organs allowing non invasive assessment of the vasculature and blood flow in various tissues. The three dimensional power doppler signal was overlaid over the three dimensional b mode volume fig 1a and b the volume was manipulated in three dimensions using the 4d view software and the power doppler signal was sequentially reduced using the softwares magi cut color only function. Three dimensional power doppler ultrasound scanning for the prediction of endometrial cancer in women with postmenopausal bleeding and thickened endometrium presented in part at the 17th world congress of the international society of ultrasound in obstetrics and gynecology florence italy oct 6 10 2007
