简要总结
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.
