A carotid Doppler is an imaging test that uses ultrasound to examine the carotid arteries located in the neck. This test can show narrowing or possible blockages due to plaque build-up in the arteries.

An ultrasound probe is placed on the patient’s neck and high frequency sound waves are used to create images of the arteries. Doppler technology is used to analyse the speed and direction of blood flow. The images are displayed on a monitor and are digitally recorded.


  • The Doctor will use probe and position it on one side of your neck. In order to obtain good quality images, it is necessary to apply some pressure with the probe.
  • Images of the arteries will be recorded and various measurements will be taken.

Patient Instructions

  • There is no specific preparation required for a carotid Doppler. You can eat and drink as usual prior to the test. Continue all prescription medications as you normally would.
  • There are no restrictions after the carotid Doppler.
