Prenatal Ultrasound InformationAre there risks associated with prenatal ultrasound?As mentioned before, there is no radiation exposure during a prenatal ultrasound. Ultrasound exams have been used for many years, and studies have never shown any harms associated with the procedure, either on a short- or long-term basis. What are 3D and 4D ultrasound?A 3D ultrasound provides a particularly clear image that resembles a photograph. A so-called 4D ultrasound provides this image in real time. Sometimes these ultrasound images are offered by non-medical providers in stores or other locations.

The test does not involve radiation and is completely safe for both mother and baby. An ultrasound examination is also known as a sonogram. The entire procedure can be performed in 30 minutes or less. Two types of ultrasound exams are used in pregnancy.

Most pregnant women receive a transabdominal ultrasound around the 20th week of pregnancy. This exam confirms that the baby is growing normally and that the placenta is attached normally. The heartbeat of the fetus is visible, and the movement of the fetus can be observed. Major birth defects can be visualized by this method, as well. In most cases, it is possible to determine the sex of the baby through an ultrasound exam at 20 weeks, but this method is not 100% accurate. You can tell the examiner whether or not you wish to know the gender of your baby at the time of the examination. Ultrasound may also be performed earlier or later in the pregnancy for specific reasons that include:
