Three-dimensional power Doppler ultrasonography during pregnancy.
OBJECTIVE
To present the appearance of fetal and placental vascular anatomic structures by three-dimensional power Doppler ultrasonography.


METHODS
Three-dimensional multiplanar imaging, surface rendering, and volume rendering were combined with power Doppler ultrasonography to show the methods, imaging artifacts, and diagnostic potential of this technology during pregnancy.


RESULTS
Fetuses with normal and abnormal vascular anatomic structures were evaluated by three-dimensional power Doppler ultrasonography. The combination of several imaging modalities (e.g., three-dimensional multiplanar imaging, surface rendering, and volume rendering) with power Doppler ultrasonography is shown.


CONCLUSIONS
Three-dimensional power Doppler ultrasonography is an important adjunctive method that can be used to characterize normal vascular development and circulatory anomalies of the fetus.
