Three-dimensional sonography-based automated volume calculation (SonoAVC) versus two-dimensional manual follicular tracking in in vitro fertilization

Abstract

Three-dimensional SonoAVC could be a useful adjunct for follicular monitoring, with a significant reduction in time and a good correlation with manual counts. However, further studies with larger sample sizes are required.

Fertility Treatment Outcomes After Follicle Tracking With Standard 2‐Dimensional Sonography Versus 3‐Dimensional Sonography‐Based Automated Volume Count: Prospective Study

“…The results showed that the use of 3D SonoAVC did not lead to an improvement in cycle parameters. Previous studies [7][8][9][10][11][12][13] have demonstrated that SonoAVC is an effective and more accurate method of measuring follicular volume and diameter than real-time 2D techniques, and the process reduces the time required for the sonographic examination. Others 14,17,18 reported that 3D SonoAVC may influence the oocyte maturation rate because it provides data that allow clinicians to time oocyte retrieval according to the follicular volume in addition to the mean follicular diameter.…”

“…The program identifies and quantifies hypoechoic regions within the 3D data set (Figure ), provides an automatic estimation of their absolute volumes, and calculates back from each volume to the mean diameter of each follicle . Measurements of follicular diameter and volume with SonoAVC were found to be more valid and accurate than those made with conventional 2D sonography . Furthermore, the individualized color code for each hypoechoic area eliminates the possibility of measuring the same follicle more than once.…”

“…The program also shortens the time needed for follicular assessment, thereby improving the clinical work flow. [7][8][9][10][11][12][13] Thus far, only 2 prospective studies have addressed the impact of the new automated follicular diameter measurement on fertility outcomes. 14,15 Raine-Fenning et al 14 showed no significant difference between manual and automated follicle tracking in terms of the number of oocytes retrieved, number of mature oocytes, or pregnancy rate.…”
