Abstract:
Objective To assess the ability of the new software SonoAVC to measure follicular volume and to compare these volume calculations with those made by conventional methods. Methods Three-dimensional ultrasound imaging was used to acquire volumetric data from the ovaries of 50 women undergoing controlled ovarian stimulation as part of in-vitro fertilization treatment. SonoAVC was used to automatically measure the volume of follicles and virtual organ computer-aided analysis(VOCAL) was also applied to measure volume, which was used as the standard of volume measurement. And the three perpendicular diameters (xyz diameters) of follicles were manually measured by conventional two-dimensional(2D) ultrasound, which were used to estimate volume using the sphere formula. And the validity of each technique was compared using limits of agreement. Results One hundred and seventy-six follicles were studied. SonoAVC and VOCAL provided highly accurate and repeatable follicular volume measurements in all cases. Volumes estimated from manually derived follicular diameter measurements were less accurate and repeatable. VOCAL took more time in follicular volume of measurement than SonoAVC and conventional 2D displays. Conclusions SonoAVC provides highly accurate, repeatable,and efficient measurements of follicular volume.
