Goodleying Scan (or Fetal Growth Scan) at The Birth Company, Harley Street, London. During this scan, we measure the baby's head, tummy and limbs and measure the baby's weight. This gives the manager how your baby will be born. We also look at how the baby moves, the amount of amniotic fluid and where the placenta is. We will also evaluate Doppler blood flow in navel blood vessels. Our clinic employs the best ultrasound technology and specialist sonographs.
