Trans-cranial Doppler Ultrasound

A Trans-cranial Doppler Ultrasound is a diagnostic examination of the blood vessels in the brain. We can examine these arteries with ultrasound through the skull. This test will assess the arteries in the brain. You may have had symptoms which may be caused by narrowing or blockages of the blood flow to the brain and your Doctor wants to confirm this or rule it out.

The Procedure

  • You will be taken to a private room. A staff member will explain the procedure and answer any questions you may have.
  • You will be asked to lie down on a couch. If its not possible for you to lie down it can be done sitting up.
  • Gel is placed on the area of interest so that the sound waves can pass through to the relevant vessels.
  • The procedure consists of scanning through the skull in front of the ear on both sides of your head. You do not feel any sensation.
  • You will hear the Doppler ultrasound from time to time as it makes a pulsing noise.
  • The examination takes approximately 30 minutes.
