RESUMO
Objective: To determine whether the Three-Dimensional Ultrasound and Three Dimensional Doppler have a role in detection of Endometrial lesions in woman with post menopausal bleeding. Methods: 36 woman in Zagazig University Obstetrics and Gynaecology Department outpatient clinics were recruited. Three-Dimensional Ultrasound and Doppler were done. Then after one week endometrial sampling was done & histological diagnosis was made. After tabulation, all data were analyzed using statistical procedures were carried with SPSS software. Result: Twenty four patients were negative for atypia or cancer and Twelve patients were positive for atypia or cancer. Mean age was 58.1 years in benign endometrium and 62.2 year in malignant endometrium (p=0.1). The mean BMI was 24 in benign and 31.75 in malignant endometrium (p<0.001). Mean endometrial thickness was 11.1 m.m in benign and 26 mm in malignant endometrium (p<0.001). The mean endometrial Volume was 5.6 cc in benign and 54.8cc in malignant endometrium (p<0.001). The VI was 2.24%and 19.5% in the two groups respectively (p<0.001). The FI was 6.7 and 27.2 in two groups respectively (p<0.001). The VFI was 3.3 and 11.5 in two groups respectively (p<0.001). In this study using endometrial volume, vascularization index percent (VI) %, flow index (FI) and vascularization-flow index (VFI) rather than endometrial thickness provided a greater sensitivity for predicting atypia or malignancy. Conclusion: The Three-Dimensional Ultrasound scanning of endometrial volume (3D-US) and Three-Dimensional Doppler Angiography (3D-DA) of the Vascular Indices (vascularization index percent, flow index, and vascularization-flow index), might predict endometrial cancer in women with postmenopausal bleeding and thickened endometrium at baseline ultrasound scanning.
