Color flow ultrasonography (Doppler) of a carotid artery - scanner and screen

Carotid ultrasonography is an ultrasound-based diagnostic imaging technique to reveal structural details of the carotid arteries, so as to look for blood clots, atherosclerotic plaque buildup, and other blood flow problems.[1]

A carotid duplex is a carotid ultrasonography carried out by duplex ultrasonography. A duplex carotid ultrasound may include a Doppler ultrasound, a special test able to reveal the movement of blood cells through the carotid arteries.
