这篇综述文章概述了速度选择性动脉自旋标记（VSASL）灌注MRI的现状，是国际医学磁共振学会（ISMRM）灌注研究组更广泛工作的一部分。自2015年发表关于脑灌注成像动脉自旋标记（ASL）的共识论文以来，该领域取得了重要进展。因此，ASL社区决定对技术开发和应用的各个方面提供一个扩展的视角。由于VSASL相对于传统方法具有独特的优势，因此有可能成为主要的ASL方法，因此有必要进行深入讨论。VSASL根据血液的速度标记血液，并在成像体积内紧邻微血管系统的位置创建磁团。因此，与空间选择性脉冲和（伪）连续ASL方法相比，VSASL对传输延迟效应不敏感。最近的技术发展提高了VSASL的鲁棒性和标记效率，使其成为一个潜在的更有利的ASL方法，在广泛的应用中，过境延迟效应的关注。在这篇综述文章中，我们（1）描述VSASL的概念和理论基础;（2）描述VSASL的不同变体及其实施;（3）提供临床采用的推荐参数和实践;（4）描述开发和实施VSASL的挑战;（5）描述其当前应用。随着VSASL的持续快速发展，本文的重点是总结VSASL的基本概念，描述现有的VSASL技术和应用，并提供建议，以帮助临床社区采用VSASL。 点击此处进行作者-读者讨论
This review article provides an overview of the current status of velocity‐selective arterial spin labeling (VSASL) perfusion MRI and is part of a wider effort arising from the International Society for Magnetic Resonance in Medicine (ISMRM) Perfusion Study Group. Since publication of the 2015 consensus paper on arterial spin labeling (ASL) for cerebral perfusion imaging, important advancements have been made in the field. The ASL community has, therefore, decided to provide an extended perspective on various aspects of technical development and application. Because VSASL has the potential to become a principal ASL method because of its unique advantages over traditional approaches, an in‐depth discussion was warranted. VSASL labels blood based on its velocity and creates a magnetic bolus immediately proximal to the microvasculature within the imaging volume. VSASL is, therefore, insensitive to transit delay effects, in contrast to spatially selective pulsed and (pseudo‐) continuous ASL approaches. Recent technical developments have improved the robustness and the labeling efficiency of VSASL, making it a potentially more favorable ASL approach in a wide range of applications where transit delay effects are of concern. In this review article, we (1) describe the concepts and theoretical basis of VSASL; (2) describe different variants of VSASL and their implementation; (3) provide recommended parameters and practices for clinical adoption; (4) describe challenges in developing and implementing VSASL; and (5) describe its current applications. As VSASL continues to undergo rapid development, the focus of this review is to summarize the fundamental concepts of VSASL, describe existing VSASL techniques and applications, and provide recommendations to help the clinical community adopt VSASL.
