This report provides practical recommendations for the design and execution of multicenter functional MRI (MC-fMRI) studies based on the collective experience of the Function Biomedical Informatics Research Network (FBIRN). The study was inspired by many requests from the fMRI community to FBIRN group members for advice on how to conduct MC-fMRI studies. The introduction briefly discusses the advantages and complexities of MC-fMRI studies. Prerequisites for MC-fMRI studies are addressed before delving into the practical aspects of carefully and efficiently setting up a MC-fMRI study. Practical multisite aspects include: (i) establishing and verifying scan parameters including scanner types and magnetic fields, (ii) establishing and monitoring of a scanner quality program, (iii) developing task paradigms and scan session documentation, (iv) establishing clinical and scanner training to ensure consistency over time, (v) developing means for uploading, storing, and monitoring of imaging and other data, (vi) the use of a traveling fMRI expert, and (vii) collectively analyzing imaging data and disseminating results. We conclude that when MC-fMRI studies are organized well with careful attention to unification of hardware, software and procedural aspects, the process can be a highly effective means for accessing a desired participant demographics while accelerating scientific discovery.
本报告基于功能生物医学信息学研究网络(FBIRN)的集体经验,为基于中心的功能磁共振成像(MC-fMRI)研究的设计和执行提供了实用建议。这项研究的灵感来自 fMRI 社区向 FBIRN 小组成员提出的许多请求,他们希望获得如何进行 MC-fMRI 研究的建议。引言部分简要讨论了 MC-fMRI 研究的优势和复杂性。在深入探讨精心、高效地建立 MC-fMRI 研究的实际方面之前,先介绍了 MC-fMRI 研究的前提条件。实用的多站点方面包括:(i)建立和验证扫描参数,包括扫描仪类型和磁场;(ii)建立和监测扫描仪质量计划;(iii)开发任务范式和扫描会话文档;(iv)建立临床和扫描仪培训,以确保随时间的一致性;(v)开发用于上传、存储和监测成像和其他数据的手段;(vi)使用巡回 fMRI 专家;以及(vii)集体分析成像数据并传播结果。我们的结论是,当 MC-fMRI 研究组织良好,并且仔细注意硬件、软件和程序方面的统一时,这个过程可以成为一种非常有效的手段,可在加速科学发现的同时,获取所需的参与者人群。
