使用2D相位对比电影MRI（PC-MRI）的血流定量长期以来一直是临床心血管方案的一部分，在心脏和瓣膜功能的评价和定量中非常有用（1）。在过去的十年中，3D电影PC-MRI（通常称为4D flow MRI）受到了越来越多的研究兴趣，并经历了重要的发展，使其更接近广泛的临床应用（2）。与标准的PC-MRI不同，4D flow MRI在所有三个空间方向上提供全面的3D解剖覆盖和流量量化。首先，它允许使用诸如流线、矢量场、等值面和体积渲染等技术来可视化3D解剖结构和流动模式。其次，它可以在任何位置进行回顾性多平面分析。当需要测量多个位置的血流时，例如在复杂先天性心脏病（CHD）的情况下，这简化了成像协议。最后，它能够计算高级血液动力学参数，例如涡度、螺旋度、壁面切应力、动能、粘性能量损失和血液淤滞。这种类型的分析的许多有用的应用程序已被证明（2，3），进一步的研究是必要的，以建立其在不同环境中的临床价值。
Flow quantification using 2D phase-contrast cine MRI (PC-MRI) has long been a part of clinical cardiovascular protocols and is extremely useful in the evaluation and quantification of cardiac and valve function (1). Over the last decade, 3D cine PC-MRI (more often called 4D flow MRI) has received increasing research interest and undergone important developments that have brought it closer to widespread clinical adoption (2). Unlike standard PC-MRI, 4D flow MRI offers comprehensive 3D anatomic coverage and flow quantification in all three spatial directions.This is beneficial for three main reasons. Firstly, it allows visualization of 3D anatomy and flow patterns, using techniques such as streamlines, vector fields, isosurfaces and volume renderings. Secondly, it enables retrospective multiplanar analysis at any location. This simplifies imaging protocols when it is necessary to measure flow in multiple locations, such as in cases of complex congenital heart disease (CHD). Finally, it enables the computation of advanced hemodynamic parameters, such as vorticity, helicity, wall shear stress, kinetic energy, viscous energy loss and blood stasis. Many useful applications of this type of analysis have been demonstrated (2, 3), and further research is warranted to establish its clinical value in different settings.
