DOPPLER ASSESSMENT

Calculation of the cerebroplacental ratio (this is an assessment of the placental reserve) from 36 weeks onwards may be useful in timing the delivery of the fetus, especially when the cerebroplacental ratio is performed weekly. Recently, there is good data now to show that planning the timing of delivery based on the estimated fetal weight and the cerebroplacental ratio reduces the risk of severe morbidity to the baby (see the study here https://pubmed.ncbi.nlm.nih.gov/38219773/). Measurement of the uterine artery Doppler on the Astraia program that the clinic uses allows the risk assessment for pre-eclampsia before 36 weeks and at term.
