Ultrasound Scans Can Tell When Baby Is Due
Ultrasound scans use sound waves to create a picture of the baby in the womb. Most women have one or more ultrasound scans during pregnancy. The two scans routinely offered during pregnancy are the nuchal scan and the anatomy scan. Sometimes other scans are performed earlier or later in pregnancy to check the growth of the baby, the position of the baby or the placenta, or for other reasons. A baby and heartbeat can be seen on the scan after 6 weeks. Before 6 weeks it is not always possible to see the baby as it is too small. You will be offered a scan between 11 and 14 weeks' gestation.

Author information: Ultrasound has a number of valuable functions in obstetrics including dating, confirming viability, counting the number of fetuses and the exclusion of gross fetal anomalies. During two routine obstetric ultrasound scans, between 11 and 14 gestational weeks and around 20 weeks, the fetus should be carefully examined after which the existence of anomalies can be confirmed or, with a limited certainty that ultrasound enables, excluded. In order to obtain high standards of ultrasound screening, a uniformed protocol is needed, which would enable standardized examination. In this paper the Novi Sad University Department of Obstetrics and Gynaecology presents a new protocol for ultrasound examination which would ensure standardized ultrasound scanning and adequate record keeping.
