What should TCD be at 20 weeks?
Ultrosonographic measurement of Transverse cerebellar diameter (TCD) was done to assess the Gestational age. Mean TCD was 17.32 mm in 14–20 weeks of gestation, 26.63 mm in 21–30 weeks and 40.73mm in 31–40 weeks.
What is a normal nuchal fold?
The nuchal fold is a normal fold of skin at the back of a baby’s neck. This can be measured between 15 to 22 weeks in pregnancy as part of a routine prenatal ultrasound. Follow-up is offered when the nuchal fold is thick (6 mm or more). Many healthy babies have thick nuchal folds.
What should be EFW at 21 weeks?
By 21 weeks, your baby weighs around 350g. From about this stage onwards, your baby will weigh more than the placenta, which, until now, was heavier than your baby. The placenta will keep growing throughout pregnancy, but not as fast as your baby.
How much should a 21 week fetus weigh?
Week 21. By the 21st week of pregnancy, the baby weighs about 400 grams and is poised to gain more weight. At this stage, the baby weighs more than the placenta (which had previously weighed more than the baby).
