血流模式与心血管系统的形态和功能密切相关。这些模式反映了心血管系统在广泛的工作负荷下保持正常血液循环的特殊适应性。准确的检索和显示的流量相关的信息仍然是一个挑战，因为在映射的特定腔室的心脏内的流速场所涉及的过程。我们回顾了目前血流可视化方法的潜力和缺陷，重点是多方向流动的采集、显示和分析。本文件分为三个部分。首先，我们提供了一个描述性的概述，在心脏流体力学的相关概念，包括出现的旋转流和变量，描绘旋涡结构。其次，我们详细介绍了主要的方法，开发图像和可视化多方向心血管血流，这主要是基于心脏磁共振，超声多普勒和对比粒子成像测速，与建议开发专用的成像协议。最后，我们讨论了潜在的临床应用和技术挑战，并提出了进一步研究的建议。（J Am科尔心脏病学杂志2012;5：305-16）（C）美国心脏病学会基金会2012年
Blood flow patterns are closely linked to the morphology and function of the cardiovascular system. These patterns reflect the exceptional adaptability of the cardiovascular system to maintain normal blood circulation under a wide range of workloads. Accurate retrieval and display of flow-related information remains a challenge because of the processes involved in mapping the flow velocity fields within specific chambers of the heart. We review the potentials and pitfalls of current approaches for blood flow visualization, with an emphasis on acquisition, display, and analysis of multidirectional flow. This document is divided into 3 sections. First, we provide a descriptive outline of the relevant concepts in cardiac fluid mechanics, including the emergence of rotation in flow and the variables that delineate vortical structures. Second, we elaborate on the main methods developed to image and visualize multidirectional cardiovascular flow, which are mainly based on cardiac magnetic resonance, ultrasound Doppler, and contrast particle imaging velocimetry, with recommendations for developing dedicated imaging protocols. Finally, we discuss the potential clinical applications and technical challenges with suggestions for further investigations.
