What the Fetal Growth & Wellbeing Scan assesses.
The examination combines standard fetal growth measurements with gestation-appropriate wellbeing observations. What can be assessed depends on fetal position, gestation and technical visibility.
Fetal biometry
Standard measurements of the head, abdomen and femur are obtained where technically possible.
Estimated fetal weight
Biometric measurements are combined to estimate fetal weight, recognising the accepted margin of error of ultrasound estimation.
Growth percentile
Estimated size is considered against gestational age using reference charts, with the result interpreted in clinical context.
Umbilical artery Doppler
Umbilical artery blood-flow waveforms are assessed using pulsed-wave Doppler, with indices interpreted against gestational age where technically obtainable.
Amniotic Fluid Index (AFI)
Amniotic fluid is assessed using an AFI measurement to provide a structured estimate of fluid volume around the baby.
Placenta, position & movement
Placental location, fetal lie or presentation and visible movements are reviewed where appropriate and technically visible.
How fetal growth is estimated on ultrasound.
Growth assessment is based on a combination of biometric measurements rather than a single measurement. Each contributes different information about fetal size and proportionality.
BPD / HC
Biparietal diameter and head circumference may be measured to assess fetal head size.
AC
Abdominal circumference is an important measurement used in estimating fetal size and weight.
FL
Femur length contributes to fetal biometric assessment and estimated fetal weight calculations.
EFW
Estimated fetal weight is calculated from biometric measurements and interpreted with gestational age and recognised ultrasound limitations.
Umbilical artery Doppler
Umbilical artery Doppler evaluates blood-flow resistance within the placental circulation. The waveform is sampled from the umbilical artery and Doppler indices are interpreted in relation to gestational age. This adds important haemodynamic information to the fetal growth assessment.
Amniotic Fluid Index (AFI)
AFI is assessed by measuring the deepest vertical fluid pocket in each of four uterine quadrants and combining the measurements. The result helps document whether amniotic fluid volume appears within the expected range for the pregnancy.
Designed for a clear, clinically useful assessment.
The examination is usually performed through the abdomen and is tailored to gestation, the baby’s position and your reason for booking.
A single scan is a snapshot. Growth trend can matter more.
Estimated fetal weight and centiles are useful, but they are not exact. When growth is being monitored clinically, the pattern across time may be more informative than one isolated measurement.
What this scan is designed for
Fetal biometry, estimated fetal weight, growth percentile, umbilical artery Doppler, amniotic fluid index (AFI), placental overview, fetal position and visible movement from 24–40 weeks.
What this scan does not replace
Formal NHS growth surveillance, specialist fetal medicine review, CTG, maternity triage, additional specialist fetal Doppler examinations beyond the included umbilical artery assessment, or emergency pregnancy care when these are clinically indicated.
Detailed measurements, explained in context.
Your Sonographer explains the fetal growth measurements, umbilical artery Doppler, AFI and other wellbeing findings during the appointment and provides a same-day digital report. Where a measurement or observation needs maternity review, you will be advised about the appropriate next step.
If your baby’s movements are reduced or changed, or you have heavy bleeding, severe pain, leaking fluid, regular contractions when not expected, severe headache or visual symptoms, fainting, fever or feel very unwell, contact your NHS maternity unit or maternity triage promptly.
Detailed answers before you book.
Common questions about fetal measurements, estimated weight, growth percentiles, placenta, fluid, Doppler, reporting and when NHS maternity assessment is more appropriate.
