Background: Intrauterine growth restriction (IUGR) is associated with an increased risk of perinatal mortality & morbidity. It accounts for a sizeable number of future unhealthy children, which is a significant burden to parents and society. IUGR can be minimized to some extent by timely & accurate detection of IUGR. Aims and objectives: To evaluate various waveforms of the umbilical artery, middle cerebral artery, ductus venosus, and cerebroplacental ratio as a predictor of adverse pregnancy outcomes in high-risk pregnancies. Materials and Methods: Eightywomen with a gestational age of 24 to 36 weeks were studied in the department of Radiodiagnosis of SAMC & PGI, Indore, Madhya Pradesh, from April 2021 to September 2022. Subjects were divided into non-complicated pregnancy [Appropriate for gestational age (AGA); n=40) and high-risk pregnancy [Small for gestational age (SGA); n=40; ≥18 years of age, with or without risk factors]. All underwent Doppler interrogation of the uterine arteries, umbilical artery, middle cerebral artery, and ductus venosus between 24-36 weeks of gestation. Results: Elevated head circumference (HC)/ abdominal circumference (AC) ratio, elevated femur length (FL)/AC ratio, presence of oligohydramnios without ruptured membrane, and advanced placental grade was more frequently observed among SGA babies. In this series, among the various risk factors, hypertension was a significant risk factor for IUGR, which other workers also accepted. Pulsatility index (PI), resistive index (RI) and systolic/diastolic (SD) ratio of uterine & umbilical arteries was significantly raised in SGA babies compared to AGA babies. In contrast, middle cerebral artery (MCA)'s PI, RI, and SD ratios were significantly lower in SGA babies than in AGA babies. Uterine artery early Diastolic Notch was seen in 11 cases & all of them delivered SGA babies. Hypertension was present in 8 of these 11 cases. Absent Diastolic Flow was detected in only one case, and the foetus ......
