High Definition Power Flow Doppler (HDPD) is a bi-directional power Doppler imaging mode. B-flow
is a direct-volume non-gated scanning tool that images blood flow in real-time. These ultrasound modalities
have improved images of the fetal cardiovascular system to near-angiographic quality. Each has its particular
advantages, which are illustrated with examples of fetal cardiovascular malformations obtained with these tools.
HDPD and B-flow provide images not available to practitioners even five years ago.
