With very fast MR imaging techniques, myocardial perfusion can be assessed by monitoring the changes of myocardial signal intensity over time following bolus injection of a contrast medium. Very fast MR imaging techniques also allow for freezing of cardiac motion that is important for coronary MR angiography and their high temporal resolution allow for coronary flow reserve measurements. In the current overview, basic principles and strategies of very fast cardiac MR imaging are presented. In the second part, applications of these fast sequences in the fields of myocardial perfusion, coronary MR angiography, and low measurements are presented.
使用超快速磁共振成像技术，可以通过监测团注造影剂后心肌信号强度随时间的变化来评估心肌灌注。超快速磁共振成像技术还能够冻结心脏运动，这对于冠状动脉磁共振血管造影很重要，并且其高时间分辨率使得能够进行冠状动脉血流储备测量。在本综述中，介绍了超快速心脏磁共振成像的基本原理和策略。在第二部分中，介绍了这些快速序列在心肌灌注、冠状动脉磁共振血管造影和低测量领域的应用。
