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.
