磁共振冠状动脉造影术（MRCA）已经存在了几十年（1）。早期报告（2）证明了该技术的主要可行性，可无创地显示冠状动脉和冠状动脉狭窄。通过从屏气成像到导航器校正数据集的转变，取得了重大进展（3）。这允许在自由呼吸期间进行测量，实现更高的空间分辨率和每个心动周期更短的采集时间。T2准备脉冲的发展，以抑制来自心肌的信号，并增强血液和周围组织之间的对比度（4），导致在良好的初步数据和强大的图像质量的基础上，在社区欣快反应。因此，进行了第一项多中心MRCA试验（5）。尽管这是心血管疾病的一个里程碑
Magnetic resonance coronary angiography (MRCA) has been around for several decades (1). Early reports (2) demonstrated the principal feasibility of the technique to visualize the coronary arteries and coronary artery stenoses noninvasively. Major advances were achieved by moving from breath-hold imaging to navigator-corrected datasets (3). This allowed measuring during free breathing, achieving higher spatial resolution and shorter acquisition time per cardiac cycle. The development of T2 preparation pulses to suppress the signal from the myocardium and enhance the contrast between blood and surrounding tissue (4) led to euphoric reactions in the community based on excellent preliminary data and robust image quality. As a consequence, the first multicenter MRCA trial was conducted (5). Even though this was a milestone for cardiovascular
