Three-Dimensional (3D) Sonography in Gynecology

Abstract

In Chang-Gung Memorial Hospital, Lin-Kou, three-dimensional (3D) sonography with power Doppler angiography had been applied in clinical evaluation since 2002. The technique can be utilized in many complicated conditions, and we had cumulative experiences in mainly three circumstances. The first one was to evaluate Mullerian duct anomaly such as HWW syndrome, uterine septum, and vaginal agenesis. The second was to assist differenciating benign from malignant tumors in uterus and ovaries. Finally, abnormal placentation such as placenta accreta was evaluated to predict the obstetric outcome. Currently, over five hundred cases of uterine anomaly and over one thousand cases of uterine tumor were collected. With all these experience, we summarized several diagnostic criterias for vessel characteristics in uterine and ovarian malignancy. Marked increased sensitivity and specificity were obtained in comparison with traditional two-dimensional sonography. Furthermore, we could provide precise and real-time images of congenital Mullerian duct anomaly and adjustable to fit individual angle of uterus with 3D sonography. MRI is also utilized for diagnosis of Mullerian duct anomaly. However, MRI has angle limitation that may affect the accurate diagnosis. It is also more expensive then 3D sonography. In our experiences, 3D sonography is a useful modality in diagnosis of Mullerian anomaly and can provide more details for treatment strategy.
