Preparation

The anomaly scan is the most detailed ultrasound most pregnancies receive. It systematically examines your baby's brain, face, spine, heart, stomach, kidneys, limbs, and blood flow, along with the placenta and fluid around the baby.

At our centre every anomaly scan is performed or supervised by a fetal medicine specialist, and the findings are explained to you in person.

What it checks

  • The baby's brain, face and spine
  • The heart chambers and major blood vessels
  • The stomach, kidneys and bladder
  • The arms, legs, hands and feet
  • The placenta, cord and the fluid around the baby

Who is it for

  • Every pregnancy; it is the standard detailed mid-pregnancy check
  • Pregnancies after IVF or other fertility treatment
  • Anyone with a previous baby affected by a structural condition
  • When another scan or blood test has raised a question
