Ultrasound in antenatal diagnosis of structural abnormalities

Prenatal diagnosis commenced in the 1980s as part of routine antenatal care. Since then, the technical improvements and standardization of routine antenatal screening around the country have led to reliable diagnosis for fetal abnormalities, allowing for appropriate management strategies to be offered in a timely fashion. The National Screening Committee Fetal Anomaly Screening Program (FASP) recommends screening for eleven fetal conditions with a detection rate of more than 50%. To achieve uniformity in prenatal diagnosis, this committee has established a series of routine views, measurements and images that should be obtained and stored during the anomaly scan. In this article we will present some of the most common structural abnormalities through a series of case presentations.
