A prenatal ultrasound scan uses sound waves to create a visual image sonogram of your baby, placenta, and uterus during pregnancy. It allows your healthcare practitioner to gather valuable information about the progress of your pregnancy and your baby’s health. During the test, an ultrasound technician sonographer uses a handheld instrument called a transducer to send sound waves through your uterus. These waves bounce off your baby, and a computer translates the echoing sounds into video images that reveal your baby’s shape, position, and movements.

Ultrasounds are a regular part of prenatal medical care for most pregnant women, and also provide parents with their first glimpses of their developing baby. Although these photographs make for nice keepsakes, most women need very few scans, and medical guidelines firmly state that ultrasounds during pregnancy should be performed only when there is a valid medical indication. According to the American Congress of Obstetricians and Gynecologists , there have been no reports of documented negative effects on the fetus from diagnostic ultrasound procedures.
But, the ACOG discourages the use of ultrasounds for nonmedical purposes because while there are no confirmed biological effects caused by scans, there’s always a possibility that some could be identified in the future.
