Definition of Ultrasound during pregnancy
Ultrasound during pregnancy: Ultrasound imaging has been done during pregnancy for over three decades. It has proven to be a very useful and very effective diagnostic procedure. A number of epidemiological studies of pregnancy ultrasound exposure have been done to look at its safety. These include studies with a highly sophisticated research design. There is no convincing evidence for any danger from ultrasound during pregnancy. (Reference: Ziskin MC. Intrauterine effects of ultrasound: Human epidemiology. Teratology 59:252-260, 1999.)
