Advances in high speed MR imaging methods are reviewed in connection with cardiac application. In cardiac MR imaging, the temporal relationship between signal acquisition and electrocardiogram has been altered with the progress from conventional spin-echo imaging to echo planar imaging. Introduction of K-space segmentation to electrocardiographic gating technique has realized a breath-hold cine MRI. As an example of functional MR imaging of the heart, assessment of left ventricular wall motion using turbo-FLASH imaging is presented. The importance of MR imaging for the functional assessment of cardiovascular system is increased by the recent progress in high speed imaging technique.
结合心脏应用对高速磁共振成像方法的进展进行了综述。在心脏磁共振成像中，随着从传统自旋回波成像到回波平面成像的发展，信号采集与心电图之间的时间关系发生了改变。将K空间分割引入心电图门控技术实现了屏气电影磁共振成像。作为心脏功能磁共振成像的一个例子，介绍了使用快速小角度激发成像评估左心室壁运动。高速成像技术的最新进展增加了磁共振成像在心血管系统功能评估中的重要性。
