Imaging of the Placenta.

Placental imaging is crucial in prenatal care, offering insights into both normal and abnormal pregnancies. Traditional methods like grayscale ultrasound and magnetic resonance imaging evaluate placental anatomy, whereas Doppler ultrasound is used for functional assessment. Recent advancements include functional magnetic resonance imaging and advanced Doppler software for demonstrating placental density and visualizing spiral arteries. B-flow and spatio-temporal image correlation are pivotal, sensitive tools for quantifying spiral artery distensibility and volume flow in early pregnancy. These techniques enhance our understanding of placental vascular architecture and promise early diagnosis and intervention for pregnancies at risk. This paper emphasizes the importance of advanced imaging in prenatal care.
