What exactly is a doppler ultrasound?

Doppler ultrasound: A doppler ultrasound uses sound waves to measure flow through vessels. When blood goes through a vessel it changes the sound waves in a way that will give us an idea if there is any obstruction or reduction in flow. This is very noninvasive and very helpful.
