| Abstract: | OBJECTIVES: 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. |
