Understanding the fetal anatomy scan: What to look for?

Pregnancy is an incredible journey filled with milestones that ensure the health and well-being of both the mother and baby. One such important milestone is the fetal anatomy scan, also known as the anomaly scan. Performed around the midpoint of pregnancy, this detailed ultrasound plays a vital role in assessing your baby’s development. Here’s everything you need to know about this essential test.

What is a fetal anatomy scan?

A fetal anatomy scan is a detailed ultrasound examination typically performed between 18 to 22 weeks of pregnancy. This scan is not just a routine checkup—it’s a comprehensive assessment of your baby’s organs, growth, and overall development.

The scan uses high-frequency sound waves to create images of the baby inside the womb. It’s a safe and painless procedure that helps doctors detect potential abnormalities and ensure your baby is growing as expected.

Why is the anatomy scan important?

This scan is a critical component of prenatal care because it:

• Detects physical abnormalities – The scan can identify congenital issues such as heart defects, neural tube defects, and limb deformities.
  

• Monitors organ development – Key organs like the brain, heart, kidneys, and liver are checked to confirm proper formation and functioning.
  

• Checks placenta and Amniotic fluid levels – The position and health of the placenta, as well as the amount of amniotic fluid, are vital for a healthy pregnancy.
  

• Provides reassurance – A normal scan can give parents peace of mind and help them bond with their baby.

What does the fetal anatomy scan examine?

During the scan, the ultrasound technician or doctor will focus on specific areas of the baby’s body:

1. Head and Brain

• The size, shape, and symmetry of the head are measured.
• The brain is assessed for proper development of structures like the ventricles and cerebellum.

2. Face and Neck

• Facial features are examined for abnormalities, such as cleft lip or palate.
• The nasal bone and neck measurements help assess the risk of chromosomal conditions.

3. Heart

• The chambers, valves, and major blood vessels of the heart are carefully evaluated.
• The scan ensures that the heart is beating normally and pumping blood effectively.

4. Spine

• The spinal column is checked for proper alignment and formation.
• The skin covering the spine is inspected to rule out neural tube defects like spina bifida.

5. Abdomen and Organs

• The stomach, kidneys, liver, and bladder are checked for size, location, and functioning.
• The umbilical cord is examined to ensure it has the normal three blood vessels.

6. Limbs

• The arms, legs, hands, and feet are inspected for proper formation and movements.
• Measurements are taken to confirm normal growth.

7. Placenta and Amniotic Fluid

• The position of the placenta (anterior, posterior, or low-lying) is noted.
• Amniotic fluid levels are measured to ensure the baby has enough cushioning.

Preparing for the fetal anatomy scan

To get the most out of your anatomy scan, here are some preparation tips:

• Drink water beforehand – A moderately full bladder enhances image clarity, making it easier to see your baby’s features.
• Wear comfortable clothes – Choose loose clothing for easy access to your abdomen during the scan.
• Bring a companion – Many clinics encourage you to bring your partner or a family member to share this special experience.

What happens during the scan?

The scan usually takes 30 to 90 minutes and is performed in a calm, comfortable environment. Here’s what you can expect:

• Positioning: You will lie on an examination table while a gel is applied to your abdomen.
  

• Ultrasound imaging: A transducer (handheld device) is moved across your belly to capture images of your baby.
  

• Detailed examination: The technician or doctor will examine various parts of your baby’s anatomy.
  

• Discussion: After the scan, your doctor will explain the findings and answer any questions you may have.

What happens if abnormalities are found?

If the scan detects any abnormalities, don’t panic. Early detection allows doctors to:

• Recommend additional tests, such as an amniocentesis or MRI, for more information.
• Plan for specialized care or interventions during pregnancy or after birth.
• Provide referrals to genetic counselors or pediatric specialists.

Conclusion

The fetal anatomy scan is an invaluable tool in ensuring your baby’s health and well-being, offering both early detection of potential concerns and peace of mind for expectant parents. This thorough examination allows healthcare providers to assess the baby’s growth and development while reassuring you that your pregnancy is progressing smoothly. Remember, early detection can make a significant difference in managing any health issues effectively.
