If you’re approaching your 20-week anatomy scan, it’s completely normal to have questions — sometimes more questions after the appointment than before.
This FAQ guide is designed to answer the most common questions Canadian parents ask about the anatomy ultrasound, in clear, reassuring language. It complements our step-by-step anatomy scan guide and focuses on the details parents often search for later, at home, when emotions and curiosity settle in.
Understanding the Anatomy Scan
-
What is an anatomy ultrasound scan during pregnancy?
An anatomy ultrasound scan (also called a detailed second-trimester or level 2 ultrasound) is a comprehensive medical ultrasound that checks your baby’s growth, major organs, and overall development during pregnancy.
-
When is the anatomy ultrasound scan done?
The anatomy scan is typically performed between 18 and 22 weeks of pregnancy, when your baby’s organs and structures are developed enough to be carefully assessed.
-
Why is the 18–22 week anatomy ultrasound important?
This scan helps assess fetal growth, organ development, placental position, and amniotic fluid levels. It can also identify findings that may require follow-up care or additional imaging.
-
Is an anatomy ultrasound scan safe for my baby?
Yes. Anatomy scans use sound waves — not radiation — and are considered safe when performed by trained professionals following established medical guidelines.
What the Anatomy Scan Checks
-
What does the anatomy ultrasound examine?
During the scan, the sonographer usually evaluates the brain, spine, heart, stomach, kidneys, bladder, limbs, placenta, umbilical cord, and amniotic fluid levels, along with taking detailed growth measurements.
-
How long does the anatomy ultrasound appointment take?
Most anatomy scans take 30 to 60 minutes, depending on your baby’s position and how easily all structures can be seen.
Preparing for Your Appointment
-
How do I prepare for my anatomy ultrasound scan?
Some clinics may ask you to arrive with a partially full bladder, especially earlier in pregnancy. Your imaging clinic will provide specific instructions when you book your appointment.
-
Can my partner or family attend the anatomy ultrasound?
Policies vary by clinic. Some locations allow one support person, while others may have restrictions. It’s best to check with your imaging centre in advance.
Results, Follow-Ups, and Common Concerns
-
What happens if the sonographer cannot see everything clearly?
If your baby’s position limits visibility, a repeat or follow-up ultrasound may be recommended. This is common and does not necessarily indicate a problem.
-
Does a normal anatomy scan mean my baby is completely healthy?
A normal scan is very reassuring, but no ultrasound can detect every condition. Some issues may not be visible or may develop later in pregnancy.
-
When will I receive my anatomy scan results?
Images are reviewed by a qualified healthcare professional and sent to your doctor or midwife, who will discuss the results and any next steps with you.
-
What happens if an abnormality is suspected?
If a difference is noted, your provider may recommend additional imaging, referrals, or testing to better understand the findings and guide care.
Gender, Technology, and What Comes Next
-
Can the anatomy ultrasound tell my baby’s sex?
In some cases, yes — if the baby’s position allows and parents wish to know. However, sex determination is not the primary purpose of the anatomy scan and cannot be guaranteed.
-
Is 3D, 4D, or HD 5D ultrasound part of the anatomy scan?
No. The anatomy scan is a medical 2D diagnostic ultrasound. 3D, 4D, or HD 5D ultrasounds are typically offered separately as elective bonding and keepsake experiences.
How UC Baby Fits Into Your Pregnancy Journey
-
Can I book a private anatomy ultrasound scan at UC Baby?
UC Baby does not replace medically indicated anatomy ultrasounds ordered by your healthcare provider. You should still attend your routine medical anatomy scan.
-
What is the difference between a medical anatomy scan and a UC Baby ultrasound?
A medical anatomy ultrasound is performed for diagnostic purposes. UC Baby’s elective 3D, 4D, and HD 5D ultrasounds are designed for bonding, extended viewing, and keepsake photos and videos.
-
Should I book a UC Baby ultrasound after my anatomy scan?
Many parents choose a UC Baby session after their anatomy scan to relax, connect with their baby, and create memories once medical assessments are complete.
-
Does UC Baby offer gender determination before or after the anatomy scan?
Yes. UC Baby offers gender blood testing as early as 7 weeks and gender determination ultrasounds starting at 16 weeks. Many families also choose to confirm or celebrate later with a 3D or HD 5D session.
-
Can family attend a UC Baby ultrasound?
UC Baby locations are designed to be family-friendly, with options for guests and live streaming so loved ones can share the experience.
