13- and 20-week ultrasound

In addition to the ultrasounds we perform within our practice, there are also ultrasounds that are part of prenatal screening. These are conducted in a specialized ultrasound center by ultrasound technicians who are trained in this area.

These examinations are intended to assess the development of the baby and any indications of physical abnormalities. It is important to know that these are screening examinations and do not provide certainty. Participation is always voluntary.

13-week scan

The 13-week scan takes place between 12 weeks and 3 days and 14 weeks and 3 days of pregnancy.

During this scan, the early development of the baby is examined.

What is assessed

What is important to know

  • The head and the first brain structures

  • The belly

  • The arms and legs

  • The overall growth and development

  • The baby is still small, so not everything is visible yet

  • Some abnormalities can be seen early

  • Sometimes something is not clearly assessable, which can cause uncertainty

  • An advantage is that if there are any anomalies, there is more time for possible follow-up steps

20-week scan

The 20-week scan takes place between 18 and 21 weeks of pregnancy, usually around 19 weeks.

This is a detailed examination in which the baby is assessed as completely as possible.

What is assessed

What is important to know
  • The heart
  • The brain
  • The abdominal organs
  • The spine
  • The arms and legs
  • The placenta and amniotic fluid

  • This is a medical and detailed examination

  • Examination for possible physical abnormalities

  • Not all abnormalities are visible

  • A normal result does not guarantee completeness

What happens with an abnormal result?

Sometimes, something seen during a scan differs from expectations, or is not entirely clear to assess. This can be alarming.

What can happen next:

  • Further investigation is recommended, such as a more detailed scan
  • Sometimes additional tests are performed, such as an amniocentesis
  • It may turn out that no abnormalities are found
  • In other cases, more clarity about the baby's health is obtained

Choosing together what suits you

Both scans are part of prenatal screening and thus a choice.

  • You can choose whether to undergo these tests or not
  • There is no right or wrong choice
  • The most important thing is what feels right for you

During the consultations, we take the time to discuss everything calmly, so you can make a choice that fits your wishes and situation.
