The anomaly scan, commonly referred to as the 20-week or mid-pregnancy scan, is an important ultrasound conducted between 18 and 20 weeks of pregnancy. This detailed examination provides a comprehensive assessment of the baby’s growth, anatomy, and development. The scan is designed to detect any structural abnormalities or anomalies, ensuring that the baby is developing as expected. In addition to identifying potential concerns, it also offers parents an opportunity to see their baby in more detail.
