Transcranial Doppler Ultrasonography

Transcranial Doppler Ultrasonography

Transcranial Doppler ultrasonography uses sound waves to measure blood circulation in the brain.

During the procedure, a smooth probe is gently moved over the scalp to transmit high-frequency sound waves through the skull. The sound waves bounce off moving blood cells, and the information from the reflected sound waves is recorded and displayed on a computer screen.

What is Transcranial Doppler Ultrasonography used for?

Transcranial Doppler ultrasonography may be used to diagnose blood vessel disorders, such as:

  • Aneurysms
  • Blood vessel abnormalities (vascular malformations)
  • Blood clots
  • Constriction of blood vessels (vasospasm)
  • Narrowing or blockages of blood vessels

Am I a good candidate for Transcranial Doppler Ultrasonography?

You may be a good candidate for transcranial Doppler ultrasonography if you are having symptoms of a blood vessel disorder.

The procedure is painless and does not involve needles, dyes, or radiation.
