A Doppler ultrasound is a medical imaging technique used to explore the blood vessels, their walls, and their flow. It is the combination of the ultrasound technique that uses ultrasound to visualize tissues or organs, in this case the blood vessel, after applying a gel to the skin, and the Doppler technique that, through this ultrasound, allows the study of the speed and direction of blood flow in these vessels. The Doppler ultrasound transmits black and white images of the blood vessels onto a screen, and a color code indicates the flow. The Doppler ultrasound is safe and is frequently done to study the arteries in the neck (SAT or supra-aortic trunks), the aorta, or the arteries and veins in the lower limbs.
