The size of the leading follicles in conjunction with serum hormone levels are used to determine the optimal time for giving the HCG trigger for IVF. Follicles have traditionally been measured manually with two-dimensional (2D) ultrasound by calculating the mean of the 2 largest follicle diameters.
Because follicles are often quite irregular in shape, measuring the follicles in the traditional fashion can result in significant inaccuracy. Another issue with manual measurements is that it is time consuming for the staff and the patients.
General Electric (GE) has software (Automated Volume Count, SonoAVC) for three-dimensional (3D) ultrasound machines that can identify follicles and automatically calculate their volumes. It then converts the measured volumes to diameters by using the sphere formula.x`
It is possible that this technology could give more accurate follicle measurements and also could increase the efficiency of the ultrasound monitoring process.
