The 20-week anatomy scan is often called the “big ultrasound,” and for good reason. Scheduled midway through pregnancy, usually between 18 and 22 weeks, this detailed appointment checks your baby’s growth, organs, and development. For many parents in Roseville, it’s also the first time seeing their baby in such detail — tiny fingers, toes, and even facial features.
While it’s an exciting milestone, the scan can also feel overwhelming. Preparing a list of questions helps you leave the appointment with clarity and confidence.
What Happens at the 20-Week Anatomy Scan
During this ultrasound, the sonographer examines:
- Baby’s brain, heart, spine, and major organs
- Measurements of the head, abdomen, and limbs
- Placenta position and blood flow
- Amniotic fluid levels
- Umbilical cord placement and heartbeat
The appointment typically lasts 45–60 minutes. If the baby is in a tricky position, you may be asked to move around or return later to complete the scan.
Key Questions to Ask Your Provider
- Is my baby’s growth on track?
Ask about measurements and percentiles. This helps you understand how your baby compares to average growth at 20 weeks. - Are all major organs developing normally?
The main goal of the scan is to check organ development. Request a simple explanation of each system reviewed. - How is the placenta positioned?
A low-lying placenta (placenta previa) can affect delivery planning. Your provider will note whether it needs monitoring. - Are amniotic fluid levels normal?
Fluid levels affect movement and lung development. Both high and low levels may require follow-up. - Do you see anything that needs re-checking?
Sometimes, parts of the body aren’t visible in one session. It’s common to return for additional views. - Can we learn the baby’s sex today?
If you’d like to know, this is usually the right time to ask. Some Roseville providers may have policies around revealing gender.
Tips for a Smooth Appointment
- Write questions down beforehand so you don’t forget
- Bring a partner or support person to share in the experience and help remember details.
- Ask for keepsake images or videos — most Roseville ultrasound clinics provide them.
Don’t hesitate to ask for clarification if medical terms feel confusing.
What to Expect in Roseville Clinics
If you’re having your scan in Roseville, most OB/GYN practices and diagnostic centers follow the same standard procedures. Plan for about an hour, including waiting time. Some clinics give immediate results, while others send reports to your OB for discussion at your next visit. Many also provide ultrasound pictures, which families cherish as an early connection to their baby.
Conclusion
The 20-week anatomy scan is both a joyful and informative milestone in pregnancy. By coming prepared with questions, you’ll not only better understand your baby’s development but also feel more confident about the weeks ahead. Remember — no question is too small when it comes to your baby’s health.
