Quantitative transvaginal two‐ and three‐dimensional sonography of the ovaries: reproducibility of antral follicle counts

Abstract

Determination of antral follicle numbers by both 2D and 3D TVS is adequate with regard to the intra- and interobserver reproducibility. The between-method reproducibility of follicle counts measured both by 2D and 3D ultrasound is moderate. When higher follicle counts are observed both interobserver and between-method reproducibilities tend to decline. If used in categorical classifications, ultrasound-based follicle counts appear to have a high level of agreement between and within observers.
