Do you always have to have an ultrasound scan?

An ultrasound scan provides us with the only means available for directly observing the unborn child in the womb. This is not just a wonderful experience for you, but it can help us detect problems at an early stage. You usually undergo a brief initial ultrasound scan during your first examination (at approx. 8 weeks), to determine how advanced your gestation period is and whether you might be expecting twins...


In order to exclude the possibility of any malformations, there are two main ultrasound scans during your antenatal treatment:

- In the 11-13th week, we calculate the risk of possible chromosome disorders (e.g. Down syndrome) by measuring the clear (translucent) space in the tissue at the back of your baby's neck and a blood sample.

- In the 20-23rd week your doctor will take a close look at the major organs such as the heart, kidneys and brain and he will note the development of the foetus. And with a little luck, you’ll find out whether it is a boy or a girl.


There is then a further examination in the 32-34th week of pregnancy to monitor the progress of the growth, and to review the estimated weight on the expected delivery date.


In addition, we offer you the opportunity of having a 3-D ultrasound scan – this is done at your request.
