What is a Growth Scan?
A growth scan is an ultrasound scan done during the last trimester of pregnancy to determine the growth of the baby. It can be done once or many times (as per the requirement). The first foetal growth scan is suggested between 28 weeks and 32 weeks of pregnancy to determine the foetal wellbeing.
The second growth scan and colour Doppler studies are done closer to the due date, between 36 and 40 weeks.
Why get a Growth Scan?
A Growth Scan is important to confirm the normal development of the foetus inside the womb.
To make it simpler, a growth scan is used to:
- Check if the baby is healthy by monitoring the baby’s movement, breathing, and stretching
- Learn the position and weight of the baby
- Determine the amount of amniotic fluid present
- Check the position and maturity of the placenta
- Check the position of umbilical cord
- Check the circulation
- Learn how a previous caesarean scar looks
- Monitor a twin pregnancy
How is it done?
A sonographer asks the patient to lie on a couch, uncovers the abdomen and applies gel on it. Then he/she passes a handheld probe over the skin of the abdomen to examine the baby’s body. The gel is applied to make sure that there is good contact between the probe and the skin. As the probe moves, a black and white 2-D image of the baby will appear on the ultrasound screen.
With the help of the image on the screen, the doctor checks how the baby is doing by checking movement, breathing, etc, and rates the development on a total score of 10 (modified Mannings score). A high number indicates that the baby is doing well whereas a lower score may suggest that the baby is not getting enough oxygen from the placenta.
The doctor also checks the circumference of the baby’s head (HC) and abdomen (AC) to check if the baby is growing well inside the womb. The scan also identifies gestational diabetes. If the amniotic fluid is more than it should be, it is a sign that the mother may have gestational diabetes.
To find out more about how the baby is doing, the sonographer may perform a Doppler scan to see how well the placenta is functioning. This is done by measuring the flow of blood between the placenta and the baby.
