In the first trimester: A 2D baby ultrasound scan is performed to verify the baby’s heartbeat, to look for multiples, and to determine estimated date of delivery. In addition, an ultrasound at this point can be invaluable in detecting any abnormalities such as an ectopic pregnancy. Sadly about 3% of women come in to discover their pregnancy has failed.

In the second trimester: A 2D ultrasound is performed for the purpose of ensuring that the baby is growing normally. At this point, measurements and a full anatomical survey are taken.

In the third trimester: An ultrasound is done to analyze foetal growth and foetal movement and to ensure foetal and maternal wellbeing. In the late stages of pregnancy it allows assessment of the presentation of the foetus i.e. to determine if the foetus is in breech or cephalic position. More recently, 4-D or dynamic 3-D scans have become available to look at the face and movements of the baby before birth. This is the mother’s first opportunity to see her baby’s face before he or she is born. This experience is exhilarating for the parents.
In addition we offer other maternity scans, see maternity ultrasound page for more info!
