Basic Facts |
|
Ultrasound is a painless, non-invasive, radiation-free diagnostic test that uses high-frequency sound waves to create images of body tissues. |
|
Duplex ultrasound also allows physicians to measure the velocity of blood flow and to see the structure of the blood vessels through which the blood is flowing. |
|
Physicians use duplex ultrasound to diagnose and examine diseases that affect the blood vessels, as well as to plan for and evaluate surgical and interventional therapies. |
