Fetal Wellbeing or Growth ultrasound scans can be performed from 14-18 weeks and assess how the baby is growing, the blood flow from the placenta to the baby in the umbilical cord, the amniotic fluid volume, the placental function and location and the position of the baby.
These types of scans can be performed because the parents want reassurance that all is going well. In some cases, serial growth scans every 2-4 weeks are required because of concerns about the growth of the baby or there have been problems in previous pregnancies. This particularly applies to twin pregnancies, because the chance of one or both babies not growing as well as they should is increased.
During this pregnancy growth scan, we measure the baby's head circumference, abdominal circumference and femur length. These measurements are plotted onto growth charts and used to calculate baby’s current weight. This is called the Estimated Fetal Weight, or EFW. This gives an indication to the size your baby will be at birth. This is best predicted from 28 weeks gestation onwards.
What if the news is not what you expected?
If there are any concerns detected on the scan, we can arrange for you to be scanned and counselled in detail by our Consultant Fetal Medicine Specialist, who can reassess the findings and counsel you in detail as to the relevance of any findings and the next steps in terms of the management of the pregnancy. Alternatively, you can choose to go back to your NHS Hospital and be referred through the NHS.
