Detailed Scan and Uterine Artery Doppler (18-24 weeks)
The 20 week Detailed Scan is an important examination of the fetal anatomy. This scan also includes checking the position of the placenta, the level of amniotic fluid and the baby’s size.
How is the scan performed?
Anomaly scans are performed ‘transabdominally’ which means over the tummy.
What information can I expect from this scan?
- information about the size of the baby and gestational age
- the heart, brain, face, spine, bowel, stomach, kidneys, limbs, hands and feet are examined for any abnormalities
- the position and appearance of the placenta
- the level of amniotic fluid around baby is checked
- the Uterine Artery Doppler is a method of predicting severe pre-eclampsia or poor fetal growth, particularly if you are considered ‘high risk’ either because of a past pregnancy history or an underlying problem such as high blood pressure.
- your baby’s gender (if you wish, but only if your baby is feeling photogenic!)
A scan can never guarantee that a baby will be born healthy and ‘normal’, but it gives very strong reassurance. As all scans at Cambridge Fetal Care are performed by experienced Fetal Medicine Consultants, this enables you to ask questions or raise concerns regarding scan findings straight away.
How to prepare for your scan
No preparation is required prior to this scan. However, on occasion the baby may be in a particularly difficult position and we may ask that you walk about for 15 minutes or so or fill or empty your bladder as this helps us to obtain the very best views.
We are very happy to give photographs at the time of the scan; there is no charge for this but the quality of the picture may depend on the baby taking up a photogenic position!
After the scan, we will give you a follow up form. We should be very grateful, as part of our audit and quality control, if you would return this after your pregnancy.
