ETSEO (13 week ultrasound)
Starting on the 1st of September 2021, all pregnant women will be offered an ultrasound around the 13th week of their pregnancy. This ultrasound is in addition to the 20-week anatomy ultrasound that checks for physical abnormalities in the baby. Both are considered medical ultrasounds.
The 13-week ultrasound is part of a research project called the IMITAS study. You can only receive the 13-week scan if you agree to participate in the study and consent to having your information used for research purposes. Your details will be used to determine the possible advantages and disadvantages of offering the 13-week scan.
Your midwives will provide you with all the information you need about the 13-week scan during the intake. After this there will be a counseling discussion where you can make a well-informed decision about the 13-week scan.
The 13-week scan is performed when you are between 12+3 and 14+3 weeks pregnant.
The sonographer will immediately tell you the findings after the ultrasound. There are three possible outcomes:
- There is no indication for an abnormality.
This is the outcome for 95 out of every 100 pregnant women à in this case no additional testing is necessary.
- The sonographer performed the ultrasound but was not able to see everything clearly.
This doesn’t necessarily mean that there is a problem with the baby. It can sometimes be because the baby is lying in a position that makes it difficult to see. A high BMI can also impact the visibility of the scan. In this case there is no additional follow-up necessary. Have you decided to do the 20-week ultrasound? Then the sonographer will reevaluate your baby at this scan.
- There is an indication that the baby has an abnormality.
In this case you can choose to have additional testing and follow-up in the AMC hospital.
The sonographers at Vida are specially trained to be able to perform the 13-week scan.
This study will take place until May 2024. After this the Minister of Health, Well-being and Sports will decide if this scan will continue to be offered as a standard part of prenatal care.
