What Is A Fetal Doppler Scan?

A Fetal Doppler is an ultrasound scan that helps assess the baby’s blood flow through the umbilical cord to various parts of the baby’s body. This scan also helps determine whether blood flows properly through the vessels and studies if sufficient oxygen and nutrients the child needs are supplied via the placenta. Normal blood flow indicates a healthy fetus, and any abnormality in the blood flow may require further intervention.

Frequently Asked Questions

A fetal doppler scan is required when:

  • The pregnancy is high-risk
  • The mother had complications in the previous pregnancy such as stillbirth, miscarriage baby with low birth weight
  • The mother is carrying multiple babies such as twins and triplets
  • The baby’s heart rate isn’t normal
  • The baby is affected by rhesus antibodies
  • The mother has a low or high BMI
  • The mother is a smoker
  • The fetus’s growth is restricted
  • The fetal movements are reduced

A fetal doppler scan is also required when:

  • The doctor requires information about the health of the placenta. Placental health is crucial for a healthy pregnancy as placenta is the organ that carries food and oxygen to the baby and any issue in the placenta can potentially harm the fetus.
  • It also checks for the baby’s general development.
  • A Doppler scan can also help determine if there are any issues or complications like clots or cysts in the mother that can cause problems before or during labour.

  • Doppler scan is performed usually during the third trimester. In some cases (like high-risk pregnancies), more than one Doppler scan will be asked by the doctor.

  • Doppler scans are safe when performed by a certified fetal medicine specialist.
     

  • A normal ultrasound will not show the rate of blood flow, but a Doppler scan will show the rate of the blood flow and blood pressure in placenta, umbilical cord, brain and heart of the baby.

    Normal ultrasound scans show only the image of the baby but Doppler can help hear the heartbeat and the amount of oxygen and nutrients the baby gets by accessing the blood flow rate.

    • A Doppler test during pregnancy can provide details about the blood circulation in the brain, kidneys, heart, umbilical cord, placenta as well as in the uterus. It helps confirm fetal heartbeat.

      Uterine artery Doppler scan:

      Uterine arteries are blood vessels which take blood to the uterus. Normally these arteries are small in size.

      But in the course of pregnancy these arteries increase in size (stretches) to provide less resistance and thus allowing more blood to flow through it.

      The Doppler scan in this area helps to check whether enough blood is reaching the womb.
