Ultrasound is the main diagnostic tool in the prenatal detection of congenital abnormalities. It allows examination of the external and internal anatomy of the fetus and the detection of not only major defects but also of subtle markers of chromosomal abnormalities and genetic syndromes. Although some women are at high risk of fetal abnormalities, either because of a family history or due to exposure to teratogens such as infection and various drugs, the vast majority of fetal abnormalities occur in the low-risk group. Consequently, ultrasound examination should be offered routinely to all pregnant women.

The scan, which is usually performed at 18–23 weeks of pregnancy, should be carried out to a high standard and should include systematic examination of the fetus for the detection of both major and minor defects.
