A Carotid Doppler is an ultrasound of the carotid arteries in your neck. This is a test used to check for narrowing or blockage in those arteries.
There is no preparation necessary for a Carotid Doppler. The test takes about one hour to perform.
During this exam, you will be asked to lie down on an exam table. You will have a pillow under your head and you will be allowed to bend your knees if that makes you more comfortable. The lights will be dimmed and you will be asked to turn your head to the left. A trained technologist will place an ultrasound probe with gel on the right side of your lower neck, near your collar bone to start the interrogation of your right carotid artery.
The arteries will be viewed from different planes wand measurements will be taken to determine the velocity of blood flow through these arteries. You may be asked not to talk during party of the exam because this could cause interference. The technologist will move the probe up towards your head while taking additional images and measurements. During parts of the test, you will hear the blood pulsating through your arteries, so you can expect parts of the test to be noisy. This procedure is then repeated on the left side of your neck.
