摘　　要：近年来,随着MR设备的发展和新序列的开发,非对比增强MR血管成像(NCE-MRA)技术发展迅速,除传统的时间飞跃法和相位对比法外,许多新方法已可用于全身各部位血管成像。NCE-MRA包括血流依赖和非血流依赖两大类成像技术,这些技术联合应用于不同的成像序列。为了提高对NCE-MRA技术的认识,促进该类技术的开发应用,对多种NCE-MRA方法的成像机制、优缺点和临床应用作一综述。In recent years, noncontrast-enhanced magnetic resonance angiography（NCE-MRA） technique has been developed rapidly in both hardware and software. In addition to the classical methods, such as time of flight（ TOF） and phase contrast（PC）, many new methods have been applied in whole-body angiography. NCE-MRA includes flow-depended and flow-independent techniques. These techniques are combined used with multiple MR scan sequences. We summarized the imaging mechanisms, advantages and limitations, and clinical applications of NCE-MRA methods to promote development and application of these techniques.
