“Doctor, everyone is telling me not to miss my Level 2 scan. Is it really that important?”

I hear this question often from expecting parents. And my answer is simple: yes, it is an important milestone in pregnancy—not because something is necessarily wrong, but because this is the stage when we can look at your baby in much greater detail.

Also called the Anomaly Scan or TIFFA Scan, the Level 2 ultrasound is usually performed between 18 and 22 weeks of pregnancy. By this time, your baby has grown enough for us to examine many organs and body structures more clearly.

What does the Level 2 scan check?

This is much more than a scan to check your baby’s growth.

During the examination, we systematically look at the brain, face, spine, heart, stomach, kidneys, bladder, arms, legs, hands and feet. We also assess the placenta, amniotic fluid, umbilical cord and the baby’s overall growth.

Think of it as your baby’s detailed health check before birth.

The scan may take time because every structure needs to be assessed carefully. And sometimes, your baby simply refuses to cooperate! If the baby is in an unfavourable position, you may be asked to walk around, have something to eat or return later for another look.

Why is 18–22 weeks the right time?

Parents sometimes ask why this detailed scan cannot be done much earlier.

I often explain it with a simple example: when a flower is still a tightly closed bud, you cannot see every petal. As it opens, its details become easier to appreciate.

Your baby’s organs develop early, but by 18–22 weeks, many structures can be examined in greater detail.

Can the scan detect every problem?

No medical test can guarantee that a baby will have no health problems.

A Level 2 scan can identify many major structural abnormalities, but some conditions may become apparent only later, while others may not be detectable on ultrasound.

Therefore, a normal scan is very reassuring, but it is not a 100% guarantee.

If something unusual is seen, it does not automatically mean that your baby has a serious problem. Sometimes the baby’s position makes an organ difficult to see, or a finding simply needs further assessment. Your doctor may recommend a repeat scan or additional tests when required.

What should parents remember?

The Level 2 scan is not meant to create fear. It is about knowing more, earlier.

As a radiologist, I know that parents may see a beautiful moving image on the screen. My responsibility is to look beyond that picture—to examine each structure carefully and provide information that can help guide the pregnancy.

A beautiful ultrasound picture is wonderful. But the real purpose of the Level 2 scan is to understand your baby’s development as thoroughly as possible.

At Pacific OneHealth, our approach is centred on combining careful imaging, clinical expertise and compassionate communication—because every expecting parent deserves not just a scan, but clarity and confidence.
