Doppler ultrasound: What is it used for?
A Doppler ultrasound evaluates blood flow and pressure in blood vessels. A Doppler ultrasound is a noninvasive test that can be used to evaluate blood flow and pressure by bouncing high-frequency sound waves (ultrasound) off red blood cells. The ... [... more] Mayo Clinic
The Digital Doppler Effect
The Doppler effect is a principle of sound and light waves moving at a great speed. Check out one of my favorite pictures of it. A familiar example is the sound of an ambulance traveling as a high pitch coming toward you, and as a lower pitch ... [... more] ClickZ
Transcranial Doppler Ultrasonography
Transcranial Doppler ultrasonography is a noninvasive method of analyzing blood flow in the brain. The blood that flows through the brain distributes nutrients to the brain and removes wastes. This flow maintains the high rate of metabolism ... [... more] Healthline
Doppler Ultrasonography
Doppler ultrasonography is a non-invasive diagnostic procedure that changes sound waves into an image that can be viewed on a monitor. Doppler ultrasonography can detect the direction, velocity, and turbulence of blood flow. It is frequently used ... [... more] Healthline
Transcranial Doppler Ultrasonography
Transcranial Doppler ultrasonography (TCD) is a noninvasive method of evaluating cerebrovascular blood flow (CBF), the flow of blood in the vessels of the brain. The TCD technology allows changes in the rate of blood flow (velocity) over time to ... [... more] Healthline

Doppler Ultrasonography
Doppler ultrasonography, also called Doppler ultrasound, is a noninvasive diagnostic procedure that uses an ultrasound scanner to convert sound waves into images of blood flow in body tissue and organs. Doppler ultrasonography does not use ... [... more] Healthline
