A Doppler ultrasound is a test that allows your doctor evaluate blood flow through major arteries and veins using reflected sound waves. Different blood flow patterns emit different sounds that can be used to proved graphs and pictures of blood flow.

How will a Doppler ultrasound reduce the need for caesarean section?
The Doppler ultrasound can produce higher resolve quality in the ultrasound picture.This increase in quality can assure the physician if there is really a need to preform a caesarean section.
What is Doppler scanning?
Doppler scanning-- A procedure in which ultrasound images are used to watch a moving structure such as the flow of blood or the beating of the heart.
How doctor use Doppler?
Doppler is used in an ultrasound exam to look for and analyze movement, usually in evaluating venous or arterial blod flow.
What does a Carotid Doppler do?
A carotid doppler is an ultrasound test that measures how much blood is flowing to the brain from the large carotid arteries. If you have suffered a stroke, your doctor will recommend this test.
What are the latest developments in ultrasound technology?
A transvaginal transducer and Doppler ultrasound uses enhanced sound waves to monitor subtle events. Color imaging is a recent development and 3-dimensional ultrasound is being researched.
What is the ultrasound principle in Doppler ultrasonography?
The ultrasound principle is this: when a high-frequency sound is produced and aimed at a target, it will be reflected by its target and the reflected sound can be detected back at its origin.
What does the medical term Doppler mean when pertaining to the fetal heart?
In the context of the fetal heart, Doppler refers to a technique used in ultrasound to assess blood flow in the umbilical cord and fetal vessels. It helps monitor the well-being of the fetus by examining the velocity and direction of blood flow.
How may ultrasound imaging with Doppler be applied in tests for stenosis?
Doppler captures the sound as the echoes bounce off of moving blood in the carotid artery, giving some indication of the amount of blockage as the ultrasound probe moves up and down the arteries on each side of the neck
What methods of visualization are available that limit radiation exposure?
general cardiac architecture and valvular function can be visualized by noninvasive cardiac ultrasound. Cardiac ultrasound and Doppler ultrasound can be used together to observe valvular insufficiency and stenosis
What is the Doppler method of fetal monitoring?
The Doppler method uses ultrasound; it involves a handheld listening device that transmits the sounds of the heart rate through a speaker or into an attached ear piece.
What exactly is the Doppler effect?
The Doppler effect is the change in frequency of a sound wave. The Doppler effect causes a siren or engine to have a higher pitch when it is approaching than it does when it is receding.
What do red and blue marks on a knee ultrasound mean?
I think you are talking about a Doppler ultrasound. The direction of blood flow is assigned the color red and blue, basically it indicates that the blood is flowing toward or away from the ultrasound transducer, respectively.
