Normal extracranial carotid arteries are easily accessible to ultrasound. The arterial contour is smooth with a thin intimal echo. Laminar flow profile is seen in all vessels. Minor turbulence can be encountered in the carotid bulb in the region of flow separation. The CCA is a mix-resistance vessel, ECA contains medium-to-high resistance signal, and the ICA demonstrates low resistance.
