An ultrasound exam is a safe diagnostic procedure that uses very-high-frequency sound waves to produce an image of many of the internal structures of the body. Originally developed in the late 1950's, over the years the machines have become better and better, resulting in images of outstanding detail and clarity.
Why have an ultrasound exam instead of an X-ray or CT scan? Ultrasound uses sound waves, not X-rays. Multiple studies have shown that these sound waves are harmless and may be used with complete safety, even on pregnant women, where CT or X-rays would be inappropriate. In some other cases, either CT or ultrasound could be used to establish a diagnosis, but ultrasound exams are typically quicker and less expensive. Your physician will order the best kind of exam for your situation.
What is the purpose of an obstetrical ultrasound exam?
An obstetrical ultrasound exam looks at the uterus and ovaries, and at the fetus. The fetus is checked to be sure that its size is appropriate for its "age." The fetus is also checked to be sure the fetal anatomy is structurally normal.Some parents have had their child's cleft detected by a sonogram (ultrasound). In the U.S., two levels of sonograms are available -- with the 3-D sonogram being more accurate.
Remember that these are ultrasound images, and that babies will look different when they are born (and also when their clefts are repaired!).
