Duplex Doppler Ultrasound

A duplex Doppler ultrasound uses standard ultrasound methods to produce a picture of a blood vessel and surrounding organs. In addition, a computer converts the Doppler sounds into a graph that provides information about the speed and direction of blood flow through the blood vessel being evaluated.

A Doppler ultrasound measures the flow of blood within the heart, veins, and arteries. It also evaluates valve movement to help detect blockages.

An arterial ultrasound can screen for stroke (carotid duplex), peripheral artery disease of the legs (lower extremity duplex), and aortic aneurysm (abdominal duplex), a common and potentially fatal disease.

A venous ultrasound is useful for identifying clots (deep vein thrombosis or DVT), varicose veins, and chronic venous insufficiency.
