Abstract: Objective: To generate the nomogram of placental thickness, volume, and vascular indices in healthy pregnant women between 12 to 20 weeks of gestation.Material and Method: An experimental cross sectional study of pregnant women, which were categorized into nine groups according to their gestational age ranging from 12 to 20 weeks of gestation, was done. Placental parameters that included placental thickness, volume, and vascular indices were measured using a Voluson E8 ultrasound machine. The measurements were correlated with gestational age.Results: Two hundred ninety four subject were included in this study. The study indicated that the placental thickness and volume significantly increased with gestational age (rp = 0.481, p<0.001 and rp = 0.837, p<0.001). The correlation between the placental volume and gestational age can be formulated according to this equation: Placental volume (cm3) = e7.584-42.45(1/GA); R2 = 0.76. Nonetheless, there is a very low correlation between the vascularization index (VI), vascularization flow index (VFI), and the gestational age (rp = 0.162, p = 0.005 and rp = 0.158, p = 0.007). The flow index (FI) was shown to have no correlation with gestational age (rp = -0.067, p = 0.254).Conclusion: From the present study, the placental thickness and placental volume significantly increased with gestational age. The VI and VFI showed poor correlation with gestational age while the FI had no correlation with the gestational age.
