Fetal ultrasound measurements can show how the baby is growing and detect abnormalities. During pregnancy many different ultrasounds measurements can be done. Gestational Sac GS The gestational sac GS is a structure that surrounds an embryo and is likely the first pregnancy structure that can be seen on ultrasound in early pregnancy. The GS encloses not only the embryo, but also the amniotic fluid, which helps to nourish and protect the developing baby. The gestational sac is the structure ultrasound technicians look for when they need to confirm the presence and viability of an early pregnancy. It can be measured across and the weeks of the pregnancy can be determined with about 5-day accuracy. Yolk Sac The yolk sac is a membraneous sac attached to the embryo. It can be seen on ultrasound between the embryo and the gestational sac.

Without dramatic birth defects to stop its use, more subtle biological sequela may go unrecognized for years to come.

Reviewers analyze huge numbers of studies and create a meta-analysis of research data about these issues. The third edition of the book concludes the following about the potential hazards of obstetric ultrasound: Any consideration of the use of diagnostic ultrasound in obstetrical practice must weigh potential benefits against potential risks. There has been surprisingly little well-organized research to evaluate possible adverse effects of ultrasound exposure on human fetuses.
