Antenatal Ultrasound Abnormalities: Soft Markers
01 In Brief
Soft markers identify an increase in fetal risk of genetic disease or malformation. These are findings detected at the 18-20 week scan can occur in a normal fetus and are not automatically considered an abnormality. However, they can be seen more frequently in a fetus with chromosomal problems and so their presence is an indication that a detailed scan should be conducted.
In isolation (not associated with other defects), and in a woman whose screening tests have not revealed any other problems, they are less likely to be of significance.
