Cardiac color Doppler

Cardiac color Doppler

Doppler ultrasound: A form of ultrasound that can identify and determine blood flow. Doppler ultrasound depends on the Doppler Effect, a change in the frequency of a wave resulting here from the motion of a reflector, the red blood cell.

There are several kinds of Doppler ultrasound:

Color Doppler – This method estimates the average velocity of flow within a vessel by color coding the information. The direction of blood flow is assigned the color red or blue, indicating flow toward or away from the ultrasound transducer.

Color Doppler depicts blood flow in a region and is used as a guide for the placement of the pulsed Doppler gate for more in depth analysis at a particular site.

Doppler ultrasound has many applications counting, for example, the detection and measurement of reduce or obstructed blood flow to the legs. Color Doppler ultrasound is done first to evaluate vessels quickly for abnormalities and to guide placement of the pulsed Doppler to gain sample volume for detailed analysis of velocities.

A Doppler ultrasound is a noninvasive test that can be used to approximation the blood flow through your blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to create images, but can’t show blood flow.

A Doppler ultrasound is a test that uses high-frequency sound waves to measure the amount of blood flow through your arteries and veins, generally those that supply blood to your arms and legs. Vascular flow studies, also known as blood flow studies, can detect abnormal flow within an artery or blood vessel.
