ABSTRACT
A considerable decline in prenatal mortality and morbidity can be attributed to the adoption of Doppler. The colour Doppler ultrasound provides us with data on blood flow and vascular resistance both directly and indirectly.
Doppler is a non-invasive technique for assessing the circulation of the foetus and placenta without interfering with human pregnancy. It provides crucial information on the foetus’s hemodynamic status and is thus a helpful diagnostic tool for recognising foetal risk and assisting in the treatment of high-risk pregnancy.
The cerebroplacental ratio, defined as “the ratio of the pulsatility index of the foetal middle cerebral artery to that of the foetal umbilical artery, will be used to evaluate the perinatal outcome in high-risk pregnancies between 30 and 36 weeks.”
