Two-dimensional ultrasound is commonly used in gynecologic patients. It has been shown to be very useful for diagnosing pelvic pathology in both asymptomatic and symptomatic patients. Three-dimensional ultrasound is a new imaging modality, which is being introduced into clinical practice. Although this technique will not probably replace two-dimensional ultrasound, it is being increasingly used. It has been reported that 3DUS is a very high reproducible technique that may have applications in the field of gynecology. These applications include imaging of the uterus, uterine cavity, adnexa and pelvic floor, as well as very interesting applications using three-dimensional power-Doppler ultrasound. The aim of this paper is addressing some technical features of three-dimensional ultrasound and reviewing its current status in clinical practice.
