The 20 week Anomaly Scan is an important detailed scan of the fetal anatomy, including placenta position, amniotic fluid and fetal growth.
At the beginning measurements will be made of the baby's head, brain, abdomen and legs. These will be plotted on a chart. We then continue a very thorough scan to check your baby's heart, brain, spine, bowel and limbs, to detect any abnormalities. This can never completely guarantee that the baby will be healthy, but it gives very strong reassurance. We also check the placenta, amniotic fluid and the umbilical cord. If you wish, you can find out the sex of your baby from this scan.
What is currently offered by the NHS?
Pregnant woman are offered two routine ultrasound scans: One at approximately 12 weeks and the other at 20 weeks of pregnancy. The 20 week anomaly scan is essentially the most important ultrasound during pregnancy. Women often come to have a scan with us as a result of the following:
- Second opinion
- More detailed scan
- Calm and relaxing environment
- As reassurance
- If the woman missed her appointment or was on holidays at time of the NHS appointment
How is the scan done?
- Anomaly scans are performed at 20-22 weeks of pregnancy and are done ‘transabdominally’ which means over the tummy.
- The heart and brain can be seen more clearly at this time of pregnancy as the baby is growing bigger.
What structures of the baby can be checked?
The heart, brain, face, spine, bowel, stomach, kidneys, limbs, hands and feet for any abnormalities
What other information can I expect?
