20 Week scan
The 20-week scan is also called the SEO (Structureel Echoscopisch Onderzoek, translation: Structural Ultrasound Examination). It can take place from 18 to 23 weeks into the pregnancy, but is preferably carried out between the 19th and 21st week.
During this ultrasound the most important structures of the baby are examined according to the FMF (Fetal Medicine Foundation) protocol of the 20 week scan. A checklist of physical structures of the baby is followed which the sonographer must see. Such as: open skull, hydrocephalus, spina bifida, the most frequent heart defects, a closed tummy, the kidneys, the arms and legs. Our sonographers have specialized themselves by certification at the FMF. If possible they can ask for permission to look further than the standard. It is also good to know that not all defects are visible with ultrasonography. Sometimes defects are expressed after the 20-week scan or even after birth. You can read more about the 20-week scan (nl) via this link.
You can view ultrasound images which are made during the 20-week scan. Your midwife, gynaecologist or general practitioner will talk about these extensively. When the sonographer is in doubt or suspects an anomaly, you will be referred to the Radboud hospital in Nijmegen or to the Rijnstate hospital in Arnhem for further examination.
You healthcare provider will always be informed about the referral and will provide you with further support.
The 20-week scan is always reimbursed by your health insurer. You should bring a referral for this investigation from your midwife, gynaecologist or general practitioner. The test cannot take place without a referral.
