Advanced Pregnancy - Growth Scans (after 26 weeks)
Why have a growth scan?
In a low risk normal pregnancy, you would get two scans during the pregnancy on the NHS, a 12 weeks scan and a 20 weeks scan.
With advancing pregnancy, an ultrasound scan can reassure the parents that the baby is growing well by doing simple measurements of baby's Head, Tummy and the thigh bone. The measurements are plotted on standardized charts which will show the baby's growth pattern. At the same time, the sonographer will look at the fluid around the baby and check that the afterbirth (Placenta) is not in the way of the birth canal. A growth scan will also include Umbilical artery Doppler studies. This study measures amount of and the pattern of blood flow in the cord. (Umbilical artery)
You can also see and hear your baby's heart beat.

- Confirm dates and Heart Beat
- Confirm baby's growth and estimate weight.
- Look at baby's anatomy again
- Check for Position of baby
- Check for Position of placenta
- Examine amount of Fluid around the baby
