大多数脑成像研究人员都会同意功能性核磁共振成像（fMRI）正在取得进展的说法。自1991年fMRI问世以来，与fMRI相关的人员、论文和摘要数量不断增加；技术和方法在稳健性和复杂性方面取得了进步；人们对信号的生理机制有了更好的理解；而且，尽管它尚未在临床环境中取得重大进展，但应用范围正在扩大。从这种乐观的、也许过于笼统的观察中产生的问题包括，功能性磁共振成像的最终理论和实践极限是什么，以及我们离这些极限还有多远。在这篇评论中，我试图提供一个功能磁共振成像的快照，因为它存在于2005年底，并给一个清晰的印象，我们不仅在“点上I和交叉t”的进步，而且在功能磁共振成像的方法和处理的根本变化正在提出，随着该领域的成熟。Elsevier B.V.出版
Most brain imaging researchers would agree with the assertion that functional MRI (fMRI) is progressing. Since fMRI began in 1991, the number of people, papers, and abstracts related to fMRI has been increasing; the technology and methodology has shown advances in robustness and sophistication; the physiology of the signal is better understood; and, even though it hasn't yet made significant headway into the clinical setting, applications are widening. Questions that stem from this optimistic and perhaps overly general set of observations include those that ask what the ultimate theoretical and practical limits of fMRI are and how close are we to approaching these limits. In this commentary, I attempt to provide a snapshot of fMRI as it exists at the end of 2005, and to give a clear impression that not only are we progressing by "dotting the i's and crossing the t's" but that fundamental changes in fMRI methodology and processing are being put forth as the field matures.
