使用多频带激励的同时多切片成像的最新进展已经显著地减少了大脑的扫描时间。这种并行成像技术的发展始于十多年前,通过最近的序列改进,多层EPI的采集时间缩短了十倍以上。这种技术最近已经变得非常有用,i)功能性MRI研究,以提高神经元网络的统计定义,和ii)基于扩散的纤维束成像,以提高可视化人脑中的结构连接的能力。几个应用和评估正在进行中,这表明这个家庭的快速成像序列的承诺。
The recent advancement of simultaneous multi-slice imaging using multiband excitation has dramatically reduced the scan time of the brain. The evolution of this parallel imaging technique began over a decade ago and through recent sequence improvements has reduced the acquisition time of multi-slice EPI by over ten fold. This technique has recently become extremely useful for i) functional MRI studies for improving the statistical definition of neuronal networks, and ii) diffusion based fiber tractography for improving the ability to visualize structural connections in the human brain. Several applications and evaluations are underway which show promise for this family of fast imaging sequences.
