  • The key to identifying fetal growth restriction is longitudinal surveillance of fetal growth. Some units consider instead a one-off scan in the third trimester, even though there is no evidence that they improve perinatal  outcome 27 28
  • There are furthermore many anecdotal examples that a one-off scan can provide false reassurance, with potentially adverse consequences.
  • A last scan between 34-36 weeks’ gestation is in fact a poor predictor of SGA, probably because it is too early to identify late onset slowing of growth.  An audit of pregnancies with a third trimester scan between 34-36 weeks, done for whatever reason, had a detection rate between 19 and 36% only 29
