稳态自由旋进(SSFP)是一种高效的MRI脉冲序列,最近才进入功能性MRI领域。迄今为止,已经提出了几种使用平衡SSFP检测BOLD信号的方法,并将在本次审查中进行讨论。在简要介绍SSFP的一般特性后,本文从功能对比机制的角度描述了过渡带SSFP和通带SSFP的截然不同的方法。然后,它讨论了这些技术的潜在优势,其次是他们的挑战和缺点。最后,它给出了一个概述的一些应用程序认为,到目前为止,作者的角度来看,这些技术的领导。本着这一特刊的精神,作者还包括了她在这一领域探索的一些个人历史。
Steady-state free precession (SSFP) is a highly-efficient MRI pulse sequence that has been a fairly recent arrival in the functional MRI realm. Several methods for using balanced SSFP to detect the BOLD signal have been proposed to date and will be discussed in this review. After a brief introduction to the general properties of SSFP, this review describes the quite different approaches of transition-band and pass-band SSFP in terms of functional contrast mechanism. It then discusses the potential advantages of these techniques, followed by their challenges and shortcomings. Finally, it gives an overview of some applications considered to date and the author's perspective on where these techniques are headed. In the spirit of this special issue, the author also includes some of the personal history underlying her own explorations in this area.
