Vascular segmentation has recently been given much attention. This review paper has two parts. Part I of this review focused on the physics of magnetic resonance angiography (MRA) and prefiltering techniques applied to MRA. Part II of this review presents the state-of-the-art overview, status, and new achievements in vessel segmentation algorithms from MRA. The first part of this review paper is focused on the nonskeleton or direct-based techniques. Here, we present eight different techniques along with their mathematical foundations, algorithms and their pros and cons. We will also focus on the skeleton or indirect-based techniques. We will discuss three different techniques along with their mathematical foundations, algorithms and their pros and cons. This paper also includes a clinical discussion on skeleton versus nonskeleton-based segmentation techniques. Finally, we shall conclude this paper with the possible challenges, the future, and a brief summary on vascular segmentation techniques.
血管分割最近受到了广泛关注。这篇综述文章分为两个部分。本综述的第一部分聚焦于磁共振血管造影（MRA）的物理学原理以及应用于MRA的预滤波技术。本综述的第二部分介绍了基于MRA的血管分割算法的最新概述、现状和新成果。这篇综述文章的第一部分关注非骨架或直接法技术。在此，我们介绍八种不同的技术及其数学基础、算法以及优缺点。我们还将关注骨架或间接法技术。我们将讨论三种不同的技术及其数学基础、算法以及优缺点。本文还包括关于基于骨架与非骨架的分割技术的临床讨论。最后，我们将以血管分割技术可能面临的挑战、未来发展以及简要总结来结束本文。
