Ealuation of three-dimensional SonoAVC ultrasound for antral follicle count in infertile women: its agreement with conventional two-dimensional ultrasound and serum levels of anti-Müllerian hormone

How to count AFC in 2 D method and Calculation of ovarian volume? Measurement of Ovarian volume 2 D ultrasound image?

The number of follicles in two planes, longitudinal and transverse, was determined and the average diameter was calculated. The antral follicle size was determined by two perpendicular diameters

Automation in calculating no of AFC by colour coding each Antral Follicle. How to measure AFC in 3 D & SonoAVC n particular?

The number of follicles in 3D is to be measured using the software, and the volume of each follicle is automatically calculated based on the anechoic intrafollicular areas in the scanner . The device is set to analyze only the region of interest with no extra-ovarian structures. The follicular images are displayed with the respective measurements and volumes. Post-processing of the images is manually performed when needed, such as AFC s that are not included in the automatic analysis and the exclusion of adjacent structures. 3D SonoAVC’s technique that allows counting the number of antral follicles by individual colors determined by the software. Their volume can also be determined based on the anechoic intrafollicular areas in the scanner that is automatically calculated.

Take home message : The results  many studies revealed that  3D SonoAVC can estimate AFCs better when compared to 2D ultrasound, mainly because it can capture images of ovaries with more than 20 follicles, resulting in a more reliable counting and was found to be faster than 2D for AFC. But the fact remains that  AFCs by both technologies presented a positive correlation to serum AMH levels.
