Abstract: Objective: To assess the predictive value of cerebroplacental ratio in detection of perinatal outcome with its components in high risk pregnancy. Materials and method: A total of 150 high risk pregnant women underwent color Doppler ultrasound after 28 weeks of gestation, Doppler indices (S/D ratio of MCA and UA ) were noted. Cerebroplacental ratio was calculated, CPR of less than 1 was considered abnormal. Perinatal outcome was noted and predictive value of cerebroplacental ratio calculated using SPSS software. Results: Cerebroplacental ratio is having higher sensitivity and negative predictive value for detection of poor Apgar score, IUGR, meconium aspiration syndrome, HIE, neonatal death and operative interference for fetal distress. Conclusion: CPR has better predictive value in detection of perinatal outcome.
