Ultrasounds early paternity dating accuracy
Before we can answer those questions, we must first understand what an ultrasound is. An ultrasound (also called sonogram) scan uses high frequency, low power, sound waves sent through the mom’s belly into the uterus.
The ultrasound image can be used to measure the size of the baby to assess its development and growth.In some cases the size of the child may complicate matters when determining gestational age using an ultrasound.The baby may be unusually big or small and moreover, sometimes the size or height of the uterus does not accurately help predict the gestation age and does not coincide with the time of pregnancy. This is one of the first questions asked by a new mom-to-be.Until recently, the ultrasound was the only non-invasive, scientific way to learn the gender of the unborn baby.
