When is a fetal Doppler ultrasound done?
Fetal Doppler ultrasound assesses blood flow in the umbilical cord, the placenta and the fetal blood vessels. It is usually performed in the third trimester (28–34 weeks), and earlier when indicated. The scan is performed by radiologist Lana Ezieshvili.
When is it ordered earlier?
- when fetal growth restriction is suspected;
- with maternal hypertension or pre-eclampsia;
- in a high-risk pregnancy;
- when the amount of amniotic fluid changes.
What does Doppler assess?
The scan assesses blood flow in the umbilical artery, the fetal middle cerebral artery and the uterine arteries. This shows whether the fetus is receiving enough oxygen and nutrients.
Conclusion
Fetal Doppler ultrasound is usually done at 28–34 weeks, and earlier if necessary. For the individual timing, book a visit with radiologist Lana Ezieshvili.
