Background: Preeclampsia is remained a major cause of maternal and perinatal morbidity and mortality, despite recent advances in antenatal care. Hypertension in pregnancy is responsible for 18% of foetal (>19 weeks of gestation) and infant mortality and 46% of infants born small for gestational age. Early screening for preeclampsia may allow vigilant antenatal surveillance and appropriate timing of foetal delivery in order to avoid serious sequelae. Doppler ultrasound has important screening and diagnostic capabilities for screening preeclampsia. Objectives: The study was aimed to assess the doppler wave form in subjects with preeclampsia. Furthermore, to observe PSV, EDV, RI, PI in different groups of study subjects from 24 to 37 weeks. Methods: This cross sectional study was carried out to observe doppler wave form in subjects with preeclampsia enrolling 40 subjects, in the Department of Radiology and Imaging, Dhaka Medical College Hospital, Dhaka, over a period of six months from 20 May 2012. Forty normal pregnancies were also included for comparison. Results: Majority (35% in normal and 37.5% in preeclampsia) of the respondents were found in the age group of 21-30 years. Unpaired t-test revealed no significant difference between mean age between two groups. Among normal group, mean±SD PSV, EDV, PI and RI were 43.94±15.41 cm/sec and 15.51 (±4.93) cm/sec, 1.12±0.0846 and 0.571 (±0.058) respectively. Mean PSV, EDV, PI and RI were 83.19±18.44 cm/sec, 11.86±5.19 cm/sec, 2.497±0.369 and 0.8255±0.087 in preeclampsia group. There was statistically significant (By unpaired t-test) difference in mean doppler indices between these two groups. It was observed that early diastolic notch was found in 90% subjects with preeclampsia. Early diastolic notch was observed in doppler wave form in 5% subject with normal pregnancy. Chi-square test showed that there was statistically significant difference in presence of early diastolic notch between normal subjects and subjects with
