SlowflowHD (GE Voluson E10, BT 19) is a new Doppler technology, which can visualize blood flow of smaller vessels in the branching vascular bed of the fetus and placenta. Its main characteristics are a high-display frame-rate, high-line density (high-resolution), and good sensitivity. In this article, we present our first experience of using SlowflowHD for the detection of small fetal peripheral vasculature.
