Duplex scan of extracranial arteries; complete bilateral study

AI EXPLANATION: A carotid duplex ultrasound is a noninvasive scan that examines the carotid arteries located on both sides of the neck. These major blood vessels carry blood from the heart to the brain. The test combines standard ultrasound imaging to visualize the structure and walls of the arteries with Doppler ultrasound technology, which detects the motion and speed of blood flowing through the vessels to check for narrowing or blockages.
