fetoplacental circulation
The vascular pathway connecting fetal and placental blood vessels, evaluated in fetal MRI and Doppler ultrasound studies.
Full Definition
Fetoplacental circulation refers to the complex vascular network that facilitates nutrient, gas, and waste exchange between the developing fetus and maternal circulation through the placenta. In pediatric radiology, this circulation is assessed through fetal MRI, Doppler ultrasound studies, and occasionally fetal echocardiography. Key vessels include the umbilical arteries carrying deoxygenated blood from fetus to placenta, and the umbilical vein returning oxygenated blood to the fetus. Abnormalities in fetoplacental circulation can indicate conditions such as intrauterine growth restriction, placental insufficiency, or congenital heart disease. Understanding these patterns is crucial for interpreting fetal imaging studies and predicting postnatal complications.
