在过去的五年中，Flow MRI取得了令人兴奋的新进展。二维图像现在通常在100-200 ms内获取，在某些情况下，5-10 ms的获取时间是可能的。这不仅是通过在现有脉冲序列的实施方面取得的进展，而且还通过数据采集策略（如压缩感知和贝叶斯方法）以及并行成像和信号增强方法的技术建议来实现的。特别是，现在实现的短成像时间尺度在瞬态流动现象的研究提供了重要的机会。(C)2013年由Elsevier Inc.出版
The past five years have seen exciting new developments in Flow MRI. Two-dimensional images are now routinely acquired in 100-200 ms and, in some cases, acquisition times of 5-10 ms are possible. This has been achieved not only by advances in the implementation of existing pulse sequences but also in data acquisition strategies, such as Compressed Sensing and Bayesian approaches, and technical advices in parallel imaging and signal enhancement methods. In particular, the short imaging timescales that are now achieved offer significant opportunities in the study of transient flow phenomena. (C) 2013 Published by Elsevier Inc.
