Prenatal ultrasounds transmit inaudible high-frequency sound waves through the abdomen and record the echoes, transforming them into video or photographs of the unborn baby. They are found to be one of the safest, most cost-effective and accurate means of keeping an eye on the development and progress of the unborn child and are also a useful means of early detection of any abnormalities within the pregnancy. Prenatal ultrasounds not only show images of the actual unborn baby, but also of the placenta, ovaries and amniotic sac, which also need to be checked throughout the pregnancy.

Studies have shown that prenatal ultrasounds cause no harmful side effects to either the mother or the baby, as they do not use radiation, (which is used in X-rays for example). They are completely safe.

Generally all pregnant women will have prenatal ultrasounds when they are about 20 weeks into their pregnancy. The doctor will then be able to confirm that the placenta is attached normally and healthy, and that the baby is growing in the uterus. He will also check the heartbeat and movement of the baby, and that there are now abnormalities present. It is usually possible to determine the gender of the baby by this time, and this is a matter of personal choice whether the parents want this information or not. Some people can’t wait to find out the gend
er, they can then start to choose a name and buy gender related toys and clothes, and decorate the nursery in a gender related fashion, but for some people they just don’t want to spoil the surprise. Be warned though, there are no guarantees that the information is correct, although the chances are pretty high. It is usual to be asked whether you want to know the gender, before the game is given away, so discuss this with your partner before attending the prenatal ultrasound.

You are likely to have an ultrasound earlier in your pregnancy if there is a possibility that you are expecting twins, or if it is needed to determine your due delivery date (or gestational age of the baby).

These days there are a number of private companies which can offer you an ultrasound scan service. If you can’t wait for the NHS, or you just want to see your baby sooner, then you can pay for more appointments. It is helpful to take any of this extra information with you when you visit your physician. You can even book a 4D ultrasound scan and have a DVD of your moving unborn baby to take home with you. This is becoming more and more popular, and some people even put copies onto video sites such as Youtube. The movement and pictures can be so clear that it is difficult to believe that the baby is not yet born, and still in the womb. You should always ensure that the company uses qualified practitioners at all times to ensure the safety of you and your unborn child.
