    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.
