Background: The present study was planned for evaluating Colour Doppler values for localization of placenta and uterine artery Doppler as predictors of preeclampsia in 18-24 weeks of gestation. Materials & methods: One hundred patients underwent ultrasound scanning between 18 and 22 weeks of gestation and were subsequently monitored until delivery. During the ultrasound examination at 18-22 weeks, the positions of the placenta and the uterine artery Doppler were assessed in all participants. The primary outcomes of the study included the incidence of preeclampsia and intrauterine growth restriction (IUGR). Both grey scale ultrasound and color Doppler imaging were utilized in the assessment. Any correlations between the radiological findings and clinical or surgical outcomes will be documented and analysed. Results: The average gestational age recorded was 22.3 weeks. In 85% of the instances, the placenta was situated centrally, whereas in the remaining 15%, it was positioned laterally. Pre-eclampsia was observed in 12% of the patients. Notably, significant correlations were found between Doppler findings and the incidence of pre-eclampsia. Conclusion: Identifying high-risk patients and proactively monitoring those at risk for preeclampsia allows for enhanced supervision, which can mitigate morbidity and enhance pregnancy outcomes.
