迄今为止，超声、CT和2D电影相位对比MRI已被用于评价门静脉系统的血流和血管形态;然而，所有这些技术都存在一些缺点，例如视野有限和难以准确评价血流。一种新的成像技术，即3D电影相位对比（4D Flow）MRI，可以一次性以时间分辨的方式采集整个腹部的血流数据，从而可以对门静脉系统中的血流进行可视化、定量和全面的评估。此外，回顾性血流分析，即，“回顾性流量测定”是可能的。虽然门静脉系统的4D Flow MRI的发展相对于动脉系统的发展有所延迟，这是由于门静脉系统的流速较低以及呼吸伪影的存在，但是随着技术的进步，最近已经发表了一些有用的报告。在这篇叙述性综述文章的第一部分中，描述了门静脉系统4D Flow MRI图像采集和分析方法的技术考虑及其结果的验证。第二部分综述了4D Flow MRI在门静脉系统的临床应用现状。在线版本包含补充材料，可通过10.1007/s11547-022-01553-x获得。
Thus far, ultrasound, CT, and 2D cine phase-contrast MRI has been adopted to evaluate blood flow and vascular morphology in the portal venous system; however, all these techniques have some shortcomings, such as limited field of view and difficulty in accurately evaluating blood flow. A new imaging technique, namely 3D cine phase-contrast (4D Flow) MRI, can acquire blood flow data of the entire abdomen at once and in a time-resolved manner, allowing visual, quantitative, and comprehensive assessment of blood flow in the portal venous system. In addition, a retrospective blood flow analysis, i.e., "retrospective flowmetry," is possible. Although the development of 4D Flow MRI for the portal system has been delayed compared to that for the arterial system owing to the lower flow velocity of the portal venous system and the presence of respiratory artifacts, several useful reports have recently been published as the technology has advanced. In the first part of this narrative review article, technical considerations of image acquisition and analysis methods of 4D Flow MRI for the portal venous system and the validations of their results are described. In the second part, the current clinical application of 4D Flow MRI for the portal venous system is reviewed. The online version contains supplementary material available at 10.1007/s11547-022-01553-x.
