Maternal and fetal blood flow discrimination in the placenta using ultrafast Doppler
Résumé
In the human placenta, maternal and fetal blood fows are in close contact, a discrimination of thoses flows could strongly help to achieve better diagnosis of placenta dysfunction. However, no current imaging modalities allow to tell these flows apart. Standard Doppler echocardiography lacks of sensibility to detect and evaluate the pulsatility of microvascularization. In this work we used an utrafast Doppler imaging to evaluate the variation of the Doppler frequency along a cardiac cycle in small vessels (100um). By studying its pulsatility we can separate maternal and fetal blood in 2D.
