An ultrasound scan uses sound waves to produce an image
of your baby (in the womb) on the screen. Click here to find out how an ultrasound scan
is carried out.
Ultrasound scans are routinely done in all hospitals around 20 weeks (referred to as the anomaly scan) to check for structural abnormalities in the baby. In additon to this 20 week scan, some hospitals also offer a scan at 12 weeks to help confirm your due date. Check your antenatal care schedule to see if your hospital offers this additional scan.
If required, ultrasound scans may also be carried out at other times during your pregnancy.
