抽象的。最初，飞行时间血管造影进入临床常规，用于血管形态成像。与相差成像相结合，血管病理学的功能和形态学评估成为可能。这些技术固有的血流依赖性和相关伪影限制了这些磁共振血管造影（MRA）技术在颅外和颅内动脉以及全身和门静脉系统的临床应用。随着高性能梯度系统的出现，一种新的、有前途的 MRA 策略已经开发出来：对比增强 3D MR 血管造影。它基于快速 3D 成像和静脉输注顺磁造影剂的 T1 缩短效应的结合。本综述提供了技术概述，并批判性地讨论了不同 MRA 技术在血管系统形态和功能评估方面的临床应用。
Abstract. Initially, time-of-flight angiography found its way into clinical routine for imaging vascular morphology. In conjunction with phase-contrast imaging, functional and morphological assessment of vascular pathology became possible. The flow dependence and associated artifacts inherent to these techniques have restricted the clinical use of these magnetic resonance angiography (MRA) techniques to the extra- and intracranial arterial, as well as the systemic and portal, venous systems. With the advent of high-performance gradient systems a new, promising MRA strategy has been developed: contrast-enhanced 3D MR angiography. It is based on the combination of rapid 3D imaging and the T1-shortening effect of intravenously infused paramagnetic contrast. This review provides a technical overview and critically discusses the clinical application for the different MRA techniques regarding morphological as well as functional assessment of the vascular system.
