20 Week Scan
Your 20-week ultrasound scan is the 2nd routine pregnancy scans you’re offered on the NHS. It’s officially known as the ‘anomaly scan’ because at this stage sonographers check for abnormalities or anomalies in the baby. The 20-week scan can happen anywhere between 18 and 20 weeks. It shows what’s going on for your baby about halfway through the pregnancy.
The sonographer will use this scan to examine the baby’s size and position. They’ll also check if their brain, heart, lungs and other internal organs are developing as they would expect.
They are also looking for signs of 11 specific conditions, some of which are more obvious than others, such as spina bifida. About nine out of 10 of the babies diagnosed with a particular condition have spina bifida.
Other conditions will be more difficult to diagnose, like heart defects. In this case, you might have a foetal echocardiogram (sometimes called a cardiac echo). This test creates a four-chamber view of your baby’s heart .
Some conditions are harder to pick up at the dating scan but might be more apparent at the anomaly scan. For example, Edward’s syndrome is usually detected during first trimester antenatal screening but is often more obvious at the 18 to 20 week scan.
You are about halfway through your pregnancy at 20 weeks, your baby is about the size of a banana . The limbs, face, neck, spine and heart are formed, so they finally look like an actual baby, not just a tiny spot on the ultrasound.
