Aim: This study was designed to evaluate umbilical artery Doppler indices [systolic/diastolic (S/D) ratio and pulsatility index (PI)] in normal fetus at term. Doppler ultrasound of umbilical arteries is widely accepted as a primary tool for quantitative analysis of fetoplacental and uteroplacental blood flow in highrisk pregnancies. Materials and methods: A total of 100 normal singleton pregnant women were recruited in this study from the Radiology Department Fatima Memorial Hospital (FMH) from August 3, 2012 to November 30, 2012. Their gestational ages were from 37 to 40 weeks. Results: A total of 100 Doppler indices measurements were performed. The values of S/D ratio were less than 3 and the values of mean PI were less than 1 from 37 to 40 weeks of gestation. Conclusion: Umbilical artery Doppler indices among normal pregnant women in our population are similar to most published reference values from other parts of the world. Clinical significance: This normative data will serve as a basis for the evaluation of the umbilical artery circulation in our population.
