Trans-cerebellar Diameter and Placental Thickness in Third Trimesteric Pregnant Women for Calculation of Gestational Age

• Conditions: Gestational Age and Weight Conditions
• Interventions: Diagnostic Test: Transcerebellar diamater; Diagnostic Test: Placental thickness

• Registration Number: NCT04240041
• Lead Sponsor: Ain Shams University

Brief Summary

Pregnant women at 32-36 weeks gestational age with sure gestational dating (based in both last menstrual period and dating ultrasound) and otherwise normal singleton pregnancy will be recruited. Ultrasonographic estimation of gestational age using combined transcerebellar diameter and placental thickness will be compared to the actual estimated gestational age.
