The applications of color Doppler sonography are reviewed in this article. Color Doppler is an efficient and time-saving means of assessing normal and abnormal flow in the fetus, making it an essential part of the echocardiographic examination for fetal congenital heart disease. In survey mode, color Doppler can be used to quickly evaluate whether flow channels are normal and to detect abnormal flow patterns. These abnormal flow patterns can then be examined further by pulsed or continuous wave Doppler, if needed. Color Doppler, which is subject to less rib shadowing than other Doppler techniques, also can help in assessing the fetal heart when there is less-than-adequate gray scale imaging.
本文对彩色多普勒超声的应用进行了综述。彩色多普勒是评估胎儿正常和异常血流的一种高效且省时的方法，使其成为胎儿先天性心脏病超声心动图检查的重要组成部分。在检测模式下，彩色多普勒可用于快速评估血流通道是否正常，并检测异常血流模式。如有需要，这些异常血流模式可通过脉冲或连续波多普勒进一步检查。与其他多普勒技术相比，彩色多普勒受肋骨阴影影响较小，在灰阶成像不足时也有助于评估胎儿心脏。
