Ultrasound Scans during pregnancy provide you and your doctor with reliable information that can be helpful to assess and analyse the progress and health of your pregnancy. Read about the different kinds of scans that are required during pregnancy in this article.

What Is an Ultrasound Scan?

Before reading about the pregnancy scan list, let us understand an ultrasound. An ultrasound scan sends high-frequency sound waves to your womb. These high-frequency sound waves reflect echoes to a computer system that converts these echoes into video images. The video images display the shape, position, and movements of the baby. It may also reveal any malformations or abnormalities in the developing baby.

In the digital image of an ultrasound scan, you will see some white, grey, and black areas. White areas are the ones that reflect the high-frequency waves the most, the hard tissues like bones. Grey areas are the low sound-reflecting sites such as soft tissues; black areas are the ones that do not reflect the high-frequency sound waves at all, such as amniotic fluid.

An ultrasound scan tests the beating of your baby's heart as well as the anatomy of their head, abdominal wall, and limbs. These days, 3D and 4D pregnancy time scan lists are gaining popularity as they also provide you with a complete and near-to-real image of your baby.

Are the different lists of ultrasound during pregnancy safe? The ultrasounds are safe and are very low in risk as they do not involve radiation like X-rays. However, unnecessary ultrasound scans should be avoided, as per medical guidelines. Studies linking ultrasound with pregnancy outcome problems are rare.
