摘　　要：相位对比法磁共振血流成像(phased-contrast magnetic resonance angiography,PC-MRA)是一种不仅能显示血管解剖结构,而且能够提供血流方向、血流速率及流量等血流动力学信息的磁共振检查技术。本文介绍了PC-MRA的基本原理、对脑血管疾病的诊断价值、优点和缺点,并对其应用前景作了展望。Phased-contrast magnetic resonance angiography is a magnetic resonance technology which can not only display the anatomic structure of blood vessel, but also provide haemodynamic informations of the blood flow direction, rate, amount and so on. The article recommends the rudiment, diagnostic values in cerebrovascular disease, advantages and defects of PC-MRA, as well as prospects the application perspective.
