作者描述了一种使用标准临床磁共振系统和体线圈进行冠状动脉超快磁共振(MR)血管成像的方法。通过使用心电门控的、分段的、超快的梯度回波脉冲序列，每段采集的八个相位编码步骤具有递增的激励翻转角度，在一次屏气内获得每个图像。通过使用重叠的4 mm厚的切片，在健康受试者中常规地从MR远端的冠脉开口显示冠状动脉。使用标准的体线圈进行冠状动脉的超快磁共振血管成像是可行的。这项技术作为一种研究工具提供了相当大的潜力，随着进一步的发展，可能会成为临床上有用的成像应用。
The authors describe a method for performance of ultrafast magnetic resonance (MR) angiography of coronary arteries with a standard clinical MR system and a body coil. Each image was obtained within a single breath hold by using an electrocardiography-gated, segmented, ultra-fast, gradient-echo pulse sequence with an incremental excitation flip angle for the eight phase-encoding steps acquired per segment. By using overlapping 4-mm-thick sections, the coronary arteries were routinely depicted from the coronary ostia distally at MR in healthy subjects. Ultra-fast MR angiography of the coronary arteries is feasible with use of a standard body coil. This technique offers considerable potential as an investigational tool and, with further development, may become a clinically useful imaging application.
