Three-dimensional Ultrasound in Evaluation of the Ovary

Three-dimensional (3D) ultrasound is an easy, important and noninvasive method for the differential diagnosis of ovarian disease in the clinical practice of obstetrics and gynecology. With advances in ultrasonographic technology, the application of higher-frequency scanning probes can evaluate the ovary in the analysis of morphological anatomy and in volume measurement, and is highly reproducible. The potential of power Doppler ultrasound with vascular indices that can further depict and quantify the microcirculation of the ovary has been extensively explored. The aim of this review is to report the present status and the recent development of 3D ultrasonography in the evaluation of the ovary. In conclusion, 3D ultrasound examination may help us to investigate the functional and potential roles of ultrasonography in clinical practice concerned with the ovary. Furthermore, 3D ultrasound may provide more substantial assistance in the differential diagnosis of various physiological or pathological conditions of the ovary.
