What is the primary purpose of a sonogram during pregnancy?

The primary purpose of a sonogram during pregnancy is to visualize the fetus. This imaging technique uses sound waves to create images of the developing baby, enabling healthcare providers to assess growth, anatomy, and well-being. It can detect important structural abnormalities and confirm the gestational age, which helps in monitoring the pregnancy's progress.

While monitoring maternal health, determining fetal heart rate, and evaluating amniotic fluid levels are important aspects of prenatal care, they are not the primary focus of a sonogram. The ultrasound's ability to visualize the fetus provides critical information regarding the pregnancy stage and fetal development, making it an essential tool in obstetrics.
