这项工作回顾了人类大脑功能性磁共振成像(fMRI)技术的最新进展,并强调了基于提高空间分辨率和特定MR对比度的更高功能特异性的推动,以揭示以前无法检测到的小规模皮质结构的功能特性。我们讨论了如何结合MR硬件,先进的采集技术和各种MR对比机制,使功能性神经成像的最新进展。然而,迄今为止,这些先进的功能磁共振成像技术仅应用于少数神经科学问题,大多数神经科学界仍然使用传统的成像技术。因此,我们讨论了即将到来的挑战和可能性,功能磁共振成像技术在人类神经科学的发展。我们希望对功能性脑成像感兴趣的读者能够了解当前和新的发展以及潜在的未来应用,即使他们没有MR物理或工程背景。我们总结了标准fMRI采集方案的功能,并指出相关文献和全面评论,并介绍了最新的发展。
This work reviews recent advances in technologies for functional magnetic resonance imaging (fMRI) of the human brain and highlights the push for higher functional specificity based on increased spatial resolution and specific MR contrasts to reveal previously undetectable functional properties of small-scale cortical structures. We discuss how the combination of MR hardware, advanced acquisition techniques and various MR contrast mechanisms have enabled recent advances in functional neuroimaging. However, these advanced fMRI practices have only been applied to a handful of neuroscience questions to date, with the majority of the neuroscience community still using conventional imaging techniques. We thus discuss upcoming challenges and possibilities for fMRI technology development in human neuroscience. We hope that readers interested in functional brain imaging acquire an understanding of current and novel developments and potential future applications, even if they don’t have a background in MR physics or engineering. We summarize the capabilities of standard fMRI acquisition schemes with pointers to relevant literature and comprehensive reviews and introduce more recent developments.
