A review of the basic physics and techniques for acquiring and evaluating magnetic resonance angiograms is provided, including time-of-flight and phase contrast techniques. Magnetic resonance (MR) angiography is becoming a routine method of evaluating carotid bifurcation atherosclerotic disease in both a screening and diagnostic capacity. The expanding clinical utility of MR angiography in the detection of intracranial aneurysms, characterization of arteriovenous malformations, and evaluation of intracranial atherosclerotic disease are also reviewed. Furthermore, MR angiography allows for the noninvasive diagnosis of arterial dissection. Magnetic resonance venography also allows the confirmation of the previously elusive and likely underdiagnosed entity of cerebral venous thrombosis.
本文介绍了获取和评估磁共振血管造影的基本物理原理和技术，包括飞行时间法和相位对比技术。磁共振（MR）血管造影正成为一种常规方法，用于筛查和诊断颈动脉分叉处的动脉粥样硬化疾病。本文还综述了MR血管造影在检测颅内动脉瘤、表征动静脉畸形以及评估颅内动脉粥样硬化疾病方面不断扩大的临床应用。此外，MR血管造影能够对动脉夹层进行无创诊断。磁共振静脉造影还能够证实之前难以捉摸且可能诊断不足的脑静脉血栓形成。
