DOPPLER ULTRASOUND

The principle of the Doppler examination of the "moving" objects based on the reflected sounds are different. Here, the blood vessels, which are active in the blood. Moving inside the red blood cells (red blood cells) sound waves are reflected back multiplier. Several vessels are doppler examination.

Doppler examination of the veins most commonly used during pregnancy:
The ultrasound examination during pregnancy according to the situation of various arteries (the arteries) and veins (veins) can be lara. These are:
- Umbilical artery (umbilical cord arteries)
- MCA (Middle Cerebral Artery, Middle cerebral (brain) arteries)
- Fetal aorta
- Umbilical vein (umbilical cord veins)
- Ductus venosus
- Intrahepatic (in the liver) veins

Doppler examination, which may be done during pregnancy?
- Anomalies
- IUGR (growth restriction) is suspected
- PIH / pre-eclampsia / eclampsia (high blood pressure situations)
- Abnormalities in the fetus / fetal disease is suspected
- Equal to the underdevelopment of the babies of multiple pregnancies
- In fetal cardiac anomalies / heart disease
- Arrhythmias (heart rhythm disorder)
- Maternal cardiovascular disease
- Previous pregnancies, growth retardation, intrauterine fetal death is
- Previous pregnancies, high blood pressure, preeclampsia is

Is there a loss of Doppler ultrasound?
To this day, or any harm to the baby doppler ultrasound demonstrated the opposite effect. But for some reason, such as to create a theoretical increase in temperature over a long period of time is still unnecessary and yapılamaması recommended.
