TCD Ultrasound

What is a Transcranial Doppler (TCD) Ultrasound?

TCD is a noninvasive and painless ultrasound technique that uses sound waves to evaluate blood flow (blood circulation) in and around the brain. There is no special contrast or radiation involved in the test.

Who should get a TCD Ultrasound?

Ultrasound of Transcranial Doppler is usually ordered by doctors if you have these indications:

  • Vasospasm
  • brain aneurysm
  • Sickle cell anemia
  • Ischemic stroke
  • Intracranial stenosis
  • Cerebral microemboli
  • Patent Foramen Ovale

Is there radiation involved?

When will I receive my results?

Once completed, you will receive your results within 3-5 business days in your LabFinder portal.

How do I prepare? Do I need to fast?
