Abstract Objective To assess the reliability of automated measurements total antral follicle count (AFC) made using Sono‐Automatic Volume Count (SonoAVC), and to compare these two‐dimensional (2D) manual three‐dimensional (3D) techniques. Methods Fifty‐five subjects aged under 40 years who had 3D transvaginal ultrasound examination in early follicular phase their menstrual cycle were prospectively recruited. datasets acquired subsequently analyzed. The AFC (2–10 mm follicles) was calculated by two observers three independent methods: 2D real‐time equivalent (2D‐RTE), multiplanar view (3D‐MPV), SonoAVC. For SonoAVC, initial (sAVC‐AA) recorded postprocessing (sAVC‐PP) then applied identify follicles that been missed or incorrectly included. Intraclass correlation limits agreement used evaluate methods. Results intra‐ interobserver best with SonoAVC followed 3D‐MPV 2D‐RTE. sAVC‐AA this reflected significantly lower mean (6.51 ± 4.79) than after techniques (sAVC‐PP, 18.42 10.53, P < 0.001; 3D‐MPV, 19.38 10.85, 2D‐RTE, 19.26 10.55, 0.001). became more comparable but still remained counts 2D‐RTE ( 0.05). Conclusion is a reliable method for measuring AFC. It takes longer perform, because need postprocessing, obtains values are those obtained However, sAVC‐PP likely be measures color codes each preventing recounting. Copyright © 2009 ISUOG.
