A carotid doppler, also known as a carotid ultrasound, is an imaging technique where an ultra sound transducer is moved along the neck of a patient. The transducer is able to emit and retrieve sound waves, and does so specifically on the carotid arteries found on either side of the neck, which are the main arteries delivering blood to the brain. The sound waves are then converted to images for physicians to determine if there are any developing blockages or closings of the carotid arteries. As they are essential for blood delivery to the brain, the carotid arteries are a prime area for a very serious stroke.
Carotid dopplers are fairly simple examinations. You will have a particular gel placed on your neck. Following this, a health care worker will then move the ultrasound transducer along both sides of the neck numerous times, in order to get visible and clear images of both your carotid arteries.
