DOPPLER INDICES OF FETAL MIDDLE-CEREBRAL AND UMBILICAL ARTERIES IN NORMAL 28–40 WEEKS PREGNANCIES

Objectives: The aim of the study was to establish normative data for pulsatility index (PI), resistive index, and cerebro placental ratio umbilical artery (UA), fetal middle cerebral (MCA) Indian pregnant women in third trimester pregnancy using multiples median percentile reference range. Methods: It a cross-sectional study; carried out at Department Obstetrics Gynaecology Radiology MGM Medical College LSK Hospital, tertiary care teaching hospital. A total 200 cases were enrolled this study. Patients with Singleton low-risk pregnancies confirmed gestational age, normal anatomy, estimated weight, born term birth weight between 10th 90th age based on LMP date, corrected if required by first/second (Before 20 weeks) sonographic parameters included Results: We found from 28 weeks 39 MCA PI showed significantly positive correlation cerebro-placental (CPR) 40th week age. no significant correlation. While 40 UA negative CPR. Conclusion: Doppler ultrasound is used as part clinical protocol surveillance pregnancies. indices CPR are currently modify scheduling antepartum and, some cases, timely delivery compromised fetus. Researchers measured pulsatility, resistivity, cardiac gestation
