What Can We See in Dating Scan?

Since dating scan is done at early first trimester, we usually can see;

©  The baby with heart beat

©  Gestational sac (it is a sac containing the baby)

©  Yolk sac (baby’s food resource, it usually disappear after the placenta take over the role)

©  The limb buds (these will develop into upper limbs and lower limbs)

Usually the sonographer will measure the Crown-Rump Length (It’s a length of baby from head to buttock) and the size of the Gestational Sac. From those measurements the ultrasound machine will calculate your baby’s current age and your baby’s expected date of delivery.
