Duplex ultrasound is a noninvasive method of evaluating the function of the systemic arteries and veins. In this review, the physical principles of duplex ultrasonography are discussed and compared to other available noninvasive tests. The clinical applications of duplex ultrasound and color Doppler imaging are reviewed and diagnostic criteria stated. Newer and more controversial applications of duplex ultrasound are presented.

UI	MeSH Term	Description	Entries
D010825	Physics	The study of those aspects of energy and matter in terms of elementary principles and laws. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)	Physic
D001808	Blood Vessels	Any of the tubular vessels conveying the blood (arteries, arterioles, capillaries, venules, and veins).	Blood Vessel,Vessel, Blood,Vessels, Blood
D006439	Hemodynamics	The movement and the forces involved in the movement of the blood through the CARDIOVASCULAR SYSTEM.	Hemodynamic
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D014652	Vascular Diseases	Pathological processes involving any of the BLOOD VESSELS in the cardiac or peripheral circulation. They include diseases of ARTERIES; VEINS; and rest of the vasculature system in the body.	Disease, Vascular,Diseases, Vascular,Vascular Disease
D055585	Physical Phenomena	The entities of matter and energy, and the processes, principles, properties, and relationships describing their nature and interactions.	Physical Concepts,Physical Processes,Physical Phenomenon,Physical Process,Concept, Physical,Concepts, Physical,Phenomena, Physical,Phenomenon, Physical,Physical Concept,Process, Physical,Processes, Physical
D018615	Ultrasonography, Doppler, Color	Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.	Doppler Ultrasonography, Color,Ultrasonography, Color Doppler,Color Doppler Ultrasonography,Color Ultrasonography, Doppler,Doppler Color Ultrasonography,Ultrasonography, Doppler Color
D018616	Ultrasonography, Doppler, Duplex	Ultrasonography applying the Doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the Doppler shift frequency.
