Ultrasound is a useful procedure for monitoring the baby’s
development in the uterus. Ultrasound uses inaudible sound waves to
produce a two-dimensional image of the baby while inside the
mother’s uterus. The sound waves bounce off solid structures in the
body and are transformed into an image on a monitor screen.
Solid structures, such as bones and muscles, reflect sound waves
and appear as light gray or white. Soft or hollow areas, like the
chambers of the heart, don’t reflect sound waves and appear dark or
black.
An ultrasound can supply vital information about a mother’s
pregnancy and her baby's health. Even though there are no known
risks for ultrasound at present, it is highly recommended that
pregnant women consult their physician before undergoing this
procedure.
