The diagnosis of fetal growth restriction (FGR) is managed with close fetal surveillance and often requires iatrogenic delivery, as there is an associated increased risk of fetal demise. However, there is no standard reference for fetal growth. We sought to compare the intrauterine growth curve of Hadlock et al (Radiology 1991; 181:129–133) to other known growth curves to determine which one best identifies fetuses at risk without overburdening the patient and health care system with unnecessary intervention.

We retrospectively reviewed charts of singleton euploid pregnancies with a diagnosis of FGR (per Hadlock) at a tertiary care center from June 2014 to May 2015. We applied the estimated fetal weights from ultrasound at diagnosis of FGR to 4 population‐based growth curves by Brenner et al (Am J Obstet Gynecol 1976; 126:555–564), Williams et al (Obstet Gynecol 1982; 59:624–632 …
