The early pregnancy volume measurements in predicting pregnancy outcome

Objective: The authors’ aim was to develop a logistic regression model based on the ultrasonographic parameters on maternities which are showing a healthy improvement process during the first trimester of pregnancy. Material and Methods: Using 2D transvaginal ultrasound imaging, the crown rump length (CRL), yolk sac (YS), and gestational sac (GS) diameters were recorded in 225 women with gestational age Results: Linear regression analyses between yolk sac volume (YSV), YSV= 0.026 + 0.0018 x CRL (r2: 0.15; p p p p Discussion: The first volume value was made in the first trimester by transvaginal ultrasonography, which showed a correlation with the age of pregnancy.
