Screening tests during pregnancy: Fetal anomaly scan

You can expect to have an ultrasound done around the mid part of your pregnancy (between 18 and 22 weeks). The main objective of this scan is to detect any abnormalities in the fetus (also known as fetal anomalies). A special gel will be rubbed across the mother’s tummy as this will enhance the image from the sound waves produced by the sonogram. The doctor will then use the ultrasound wand (called a transducer) and move it across the tummy.

Through this fetal anomaly scan, images of the baby can be seen, measured and recorded. You will be able to look out for the size of the baby and determine the age. Pictures from the scan can also be kept and recorded on a DVD as a memento.
