What is the normal anomaly scan report?
An anomaly scan, also known as a mid-pregnancy scan, takes a close look at your baby and your womb (uterus). The person carrying out the scan (sonographer) will check that your baby is developing normally, and look at where the placenta is lying (NICE 2021, PHE 2021a).
What does anomaly scan reveal?
Detect birth defects, such as a spina bifida or heart problems. If you are concerned about the chances of chromosome issues, this scan can search for subtle markers that may suggest a higher risk that your baby may have a syndrome. If you want to know your baby’s gender this can usually be seen at this scan.

Studies have shown that scans to determine the sex of the baby can be wrong 1-3% of the time so you must accept there is a small possibility of being told the wrong sex.
Can a girl be mistaken for a boy at 20 weeks?
We tend to overpredict boys more often than girls. This can happen, for example, if the baby is developing slowly and the tubercle hasn’t begun to point up or the umbilical cord is mistaken for a penis. While gender prediction is much more accurate during the 20-week ultrasound, there’s still a chance it can be wrong.
What is the BPD of baby boy?
At 24 weeks, the 50th percentile BPD for boys (60.4 mm) is significantly higher as compared to girls (58.9 mm, p < 0.001; Additional file 5). This corresponds to a difference of three gestational days.
How can you tell the gender of an anomaly scan?
We can tell the sex of the baby at the 12 week scan by assessing the direction of the nub. This is something that can be identified on babies at this stage and if it points vertically then it is likely to be a boy. If it points horizontally then it is likely to be a girl.
