Spectral Doppler ultrasound, an important diagnostic tool for the functional assessment of various organs, as yet has no major use in prenatal diagnosis due to the conventional technique's limitation of analyzing only one site at a time. Our aim was to develop a new modality that shows simultaneous studies of multiple sites in a vascular area, which should provide improved assessment of hemodynamic status of vascular systems.
The new Doppler modality features automatic acquisition and analysis of blood flow in multiple sites over a large area. The quantitative Doppler data are presented as color-coded maps of the spectral Doppler indices overlaid on the gray-scale sonographic images and as histograms of indices distribution.
Serial sequences of Doppler measurements in the umbilical artery were taken in 14 women. The reproducibility of the new modality was confirmed.
Our new Doppler modality provides reproducible and reliable data. This method is a viable alternative to the traditional Doppler ultrasound and might offer better assessment of feto-placental circulation.
频谱多普勒超声是评估各器官功能的重要诊断工具，但由于传统技术一次只能分析一个部位，目前在产前诊断中尚未得到广泛应用。我们的目标是开发一种新方法，能够同时研究血管区域的多个部位，从而更好地评估血管系统的血流动力学状态。
这种新的多普勒方法能够自动采集和分析大面积多个部位的血流情况。定量多普勒数据以频谱多普勒指数的彩色编码图叠加在灰阶超声图像上的形式呈现，同时还以指数分布直方图的形式呈现。
对14名女性的脐动脉进行了一系列多普勒测量。新方法的可重复性得到了证实。
我们的新多普勒方法能够提供可重复且可靠的数据。该方法是传统多普勒超声的可行替代方案，可能会更好地评估胎儿 - 胎盘循环。
