Özet
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 <11 weeks. Simplified V = 0.523 × length × height × width formula was used for the volume calculations. The results which ended in abortion were not included in the study. Results: Linear regression analyses between yolk sac volume (YSV), YSV = 0.026 + 0.0018 × CRL (r2: 0.15;p < 0.001), gestational sac volume (GSV), GSV= -9.6 + 1.7 × CRL (r2: 0.52;/? < 0.001), and embryo volume (EV), EV = -1.64 + 0.18 × CRL (r2: 0.4; p < 0.001), and CRL was made and a linear relationship was detected. The volume measurements showed a meaningful correlation with the week of pregnancy. The space in the GS (GS volume-embryo volume) increased as the age of pregnancy became older (r2 = 0.46; p < 0.001). Discussion: The first volume value was made in the first trimester by transvaginal ultrasonography, which showed a correlation with the age of pregnancy.
