静息状态功能磁共振最早是由Biswal等人描述的。自1995年以来，它被广泛用于健康受试者和各种神经学、神经外科和精神疾病患者。与基于范例或基于任务的功能磁共振不同，RS-fMRI不需要由受试者执行任何特定的任务。RS-fMRI信号的低频振荡已被证明与自发神经活动有关。有许多不同的方法来分析RS-fMRI数据。在这篇评论文章中，我们将简要描述其中的几种方法，并强调每种方法的优点和局限性。这是为了帮助和便利在临床环境中采用和使用rs-fmri，帮助神经放射科医生熟悉这些技术，并将其应用于神经和精神疾病患者的护理。
Resting-state functional MRI (rs-fMRI) was first described by Biswal et al. in 1995 and has since then been widely used both in healthy subjects and patients with various neurological, neurosurgical and psychiatric disorders. As opposed to paradigm- or task-based functional MRI, rs-fMRI does not require any specific task to be performed by the subjects. The low-frequency oscillations of the rs-fMRI signal have been shown to relate to the spontaneous neural activity. There are many different ways to analyze rs-fMRI data. In this review article, we will briefly describe a few of these and highlight the advantages and limitations of each. This is to help and facilitate the adoption and use of rs-fMRI in the clinical setting, helping neuroradiologists to become familiar with these techniques and to apply them for the care of patients with neurological and psychiatric diseases.
