Duplex scan of upper extremity arteries or arterial bypass grafts; complete bilateral study

AI EXPLANATION: An upper extremity arterial Doppler ultrasound is a noninvasive imaging test that evaluates blood circulation through the arteries of both arms. The scan uses high-frequency sound waves to create detailed images of the blood vessels and measure how fast blood travels through them. It helps identify narrowed vessels, blockages, blood clots, or assess previous arterial bypass grafts without requiring radiation or incisions.
