Comparing Diagnosis of Fetal Growth Restriction and the Potential Impact on Management and Outcomes Using Different Growth Curves.

Objectives: 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.
