Long-term follow-up of children exposed to scans before birth did not indicate that scans have a detrimental effect on children's physical or intellectual development.

Diagnostic ultrasound examination may be employed in a variety of specific circumstances during pregnancy such as after clinical complications, or where there are concerns about fetal growth.
