title: Clinical application of volume estimation based on three-dimensional ultrasonography.
abstract: The development of three-dimensional sonography represents a milestone in the history of diagnostic ultrasound. It has become possible to evaluate a region of interest not only in the horizontal and vertical planes but also in a third, i.e. the frontal, plane. Among other possible applications, this technique greatly facilitates volume estimation. The objective of the present study was to evaluate the accuracy and precision of volumetry based on three-dimensional sonography. The results demonstrate a good correlation between estimated volumes and the volumes measured by transvaginal needle-guided follicle aspiration performed under sonographic visualization. Our findings confirm the conclusion of previous studies that three-dimensional sonography is making a valuable contribution to imaging techniques.
