This test uses sound waves to create images of the blood flow through certain arteries in your unborn baby's head.



An obstetric ultrasound uses sound waves to create images of your uterus and unborn baby.

  • This ultrasound uses sound waves to create images of the blood flow through certain arteries in your unborn baby's head.

Your healthcare provider may order this ultrasound to determine:

  • The flow of blood through your unborn baby's cerebral artery. The blood flow is usually faster if your unborn baby does not have enough red blood cells in their blood.
  • If your unborn baby needs a blood transfusion.

Here are some things you should know before having an ultrasound.

  • You will be asked to drink water before the test. Having a full bladder will help make the uterus and unborn baby more visible.
  • Your healthcare provider can tell you other things you need to do to prepare.
  • You may want to wear a loose two-piece outfit, so you can remove just the bottom for the exam.
  • Ultrasounds are usually painless.
  • The exam usually takes 15 to 20 minutes.
  • Usually, only one ultrasound is needed for each pregnancy.

In some cases, a technician will move a probe over your abdomen.

  • The probe will be covered with a clear gel.
  • The gel helps send the sound waves to the computer.
  • Sometimes, the end of the probe will need to be put into your vagina to get better pictures.

The costs for this test include the charge for the test (facility charge) and physician charges (for performing or interpreting the test). You may get separate bills from the facility and the physician's office.

What should I ask my healthcare provider before having this test?

  • Is there any special preparation for the test? (If so, get clear instructions on what you need to do.
  • Why are you ordering this test? Will the test results change how we take care of my pregnancy? If not, do I need the test?
