Comparison between cerebroplacental ratio and umbilicocerebral ratio in predicting adverse perinatal outcome at term

Objective Cerebroplacental ratio (CPR) has been associated with adverse perinatal outcome irrespective of fetal weight. More recently, it has been proposed that the ratio between umbilical and middle cerebral artery pulsatility index, the umbilicocerebral ratio (UCR) had a higher diagnostic accuracy compared to CPR in predicting adverse outcome. The aim of the study was to compare the diagnostic accuracy of CPR and UCR in predicting adverse...
