title: Comparison of manual and automated measurements of monodominant follicle diameter with different follicle size in infertile patients.
abstract: This study evaluated the consistency of manual and automated measurements of monodominant follicle diameter with different follicle size in infertile patients. Transvaginal two-dimensional (2D) ultrasound and SonoAVC (Sonography-based Automated Volume Calculation) were both performed in 226 infertile patients with monodominant follicle growth. 2D diameters were separately compared with SonoAVC-generated d(V) and m-d values in different follicle category, i.e. >10 to 14 mm, >14 to 18 mm, >18 to 22 mm and >22 mm. There was moderate degree of consistency between 2D diameter and SonoAVC-generated parameters regardless of follicle size. The mean differences were 0.82 mm between 2D diameter and SonoAVC-generated d(V) value, and 0.22 mm between 2D diameter and SonoAVC-generated m-d value, respectively. The discrepancy of manual and automated measurements tended to increase as follicle size increased. Our study suggested that compared with manual measurement, SonoAVC might underestimate follicle size. The absolute size of a follicle affected the consistency of two techniques.
