Vascular Imaging**

Doppler ultrasound is a special technique used to examine blood flow through a blood vessel,
including the body’s major arteries and veins in the abdomen, arms, legs and neck. A Doppler
ultrasound study may be part of a vascular ultrasound examination. Doppler images can help to
determine blockages of blood flow (such as a blood clot) and build up of plaque inside a blood
vessel.
