Anatomy Scan at 18–22 Weeks: What to Expect, How to Prepare & Common Questions

As you approach the anatomy scan, it’s completely normal to feel a mix of excitement and a little anxiety. This milestone marks a key point in your pregnancy—usually between 18 and 22 weeks—when a detailed ultrasound examines your baby’s growth and development. It’s a routine part of care, but also a special moment.

What Is the Anatomy Scan?

The anatomy scan is a comprehensive ultrasound that checks your baby’s development. The sonographer will carefully look at the brain, heart, spine, stomach, kidneys, limbs, face, and other key organs. They’ll also assess the placenta, amniotic fluid, and umbilical cord. It’s a wonderful way to see how your baby is growing and to ensure everything is progressing as expected.

How Long Does It Take?

On average, the scan lasts between 30 and 60 minutes. The exact time may vary based on your baby’s position and how cooperative they are.

Preparing for Your Scan

Wear comfortable clothing, ideally something that makes it easy to access your belly. Your provider might give specific instructions; sometimes they suggest a full bladder early in pregnancy, but at this stage, it’s usually not required. Staying hydrated overall is always a good idea. If you’d like your baby to be a bit more active, a light snack beforehand might gently encourage some movement. But don’t worry—if your baby is calm, the sonographer can guide you to shift positions or take a short walk if needed.

What Will They Check?

The sonographer will measure your baby’s head, brain structures, heart chambers, spine alignment, limbs, kidneys, stomach, bladder, and more. They’ll also note the placenta’s position and the amniotic fluid levels. This scan helps ensure your baby is growing as expected. If anything needs further assessment, your provider will walk you through next steps.

Questions to Ask During the Scan

Feel free to ask about your baby’s position, measurements, or even the placenta’s location. It’s a good time to ask about anything you’re curious about. And remember, if the sonographer is quiet, it’s just because they’re focusing on capturing precise images.

It’s Okay to Feel Anxious

Many parents feel a bit nervous before this scan. Just know that it’s a routine part of care and, most of the time, a reassuring experience. Seeing your baby on the screen can be a wonderful bonding moment.

After the Scan
