What does Doppler ultrasound measure?

1. Lung capacity
2. Heart rate
3. Blood flow through blood vessels
4. Brain activity

How does Doppler ultrasound work?

1. Using magnetic resonance imaging
2. Measuring temperature changes
3. Sending electrical impulses
4. Bouncing high-frequency sound waves off red blood cells

What can a regular ultrasound show?

1. Muscle strength
2. Blood flow
3. Nerve activity
4. Images of body structures

What is the main difference between Doppler ultrasound and regular ultrasound?

1. Regular ultrasound uses higher frequency waves
2. Regular ultrasound is more cost-effective
3. Doppler ultrasound can show blood flow
4. Doppler ultrasound is more time-consuming

Why is Doppler ultrasound considered noninvasive?
