The Importance of the Cerebroplacental Ratio in the Evaluation of Fetal Well-Being in SGA and AGA Fetuses

Abstract

(Am J Obstet Gynecol. 2015;213(1):5–15) The cerebroplacental ratio (CPR) is becoming an important way to assess fetal well-being and risk of adverse pregnancy outcome in fetuses diagnosed as small for gestational age (SGA) and appropriate for gestational age (AGA). Recent reports have indicated that abnormal CPR scores are associated with adverse perinatal events, fetal distress, and a higher rate of emergency cesarean deliveries. This article reviews studies where CPR has been used to evaluate SGA and AGA fetuses to predict adverse outcomes during labor and subsequent neonatal complications.
