To date, ultrasound and Doppler study took the bottom of the main places in the technique of complex examination of pregnant women. What is an ultrasound studies in obstetrics: Technology for images based on the change in power and frequency of ultrasonic waves reflected from the object of its research on fabrics that affects the ultrasonic radiation, converting it into heat energy. Thermal effect on tissues depends on: Characteristics of devices (power) mode (UDC, pulsed Doppler and B-mode), exposure time (research) This implies that the dose in hundredths of W/cm2. small to cause an embryo or fetus obvious harm. Despite the fact that no reliable information about the damaging effect of this imagistic a product of conception, to conduct ultrasound and Doppler studies during pregnancy should only be indicated.

Doppler conducted with 18 weeks of gestation provides an estimate of the rate of blood flow and to identify possible irregularities in utero-placental-fruit system. There are individual time studies, depending on the identified pathology. Unfortunately not all the vices with ultrasonic scanning.
