DOPPLER ULTRASOUND

The principle of Doppler examination "moving" is based on the fact that the reflected sound from the different bodies. Here fool moving within the blood vessels. Blood in the moving red cells (erythrocytes to) sound waves are reflected back multiplier. Doppler examination is carried out on various vessels.

The most commonly used in vascular Doppler examination in pregnancy:

- MCA (Middle Cerebral Artery, middle cerebral (brain) artery)
- Fetal aortic
- Umbilical vein (collects the umbilical cord vessels)
- Ductus venosus
- Intrahepatic (in the liver) veins

- IUGR (retardation) suspected
- PIH / pre-eclampsia / eclampsia (high blood pressure with conditions)
- Abnormalities in the fetus / fetal disease suspected
- Equal development of the baby in multiple pregnancies
- Abnormalities in the fetus heart / heart disease
- Arrhythmias (heart rhythm disorder)
- Maternal cardiovascular diseases
- Growth retardation in previous pregnancies, intrauterine fetal death have
- High blood pressure in previous pregnancy, that preeclampsia

Doppler ultrasound is there damage?
So far Doppler ultrasound a baby any harm or adverse effects have not been shown. However, theoretically, for some reason such as the inability to create a temperature rise still it recommended unnecessary and too long.
