摘要

在过去二十年里,超高场 7-Tesla (7T) 磁共振成像技术在多发性硬化症(MS)研究中的应用大幅增长。随着最近监管部门批准 7T 扫描仪于 2017 年和 2020 年用于临床,该技术在常规护理中的使用在未来几年将继续增加。在此背景下,北美多发性硬化症成像合作组织(NAIMS)于 2023 年 2 月召开了一次研讨会,回顾 7T 技术以前和现在在多发性硬化症研究中的使用情况,以及未来潜在的研究和临床应用。在这次研讨会上,专家们的任务是回顾当前的文献并提出一系列共识声明,这些声明已经过 NAIMS 的审查和批准。在这篇综述和共识文件中,我们介绍了在多发性硬化症研究中使用 7T 磁共振成像的背景,强调了该技术在识别和量化多发性硬化症病理方面的前景,而低磁场磁共振成像较难显示这些病理,如灰质病变、顺磁性边缘病变、脑外膜强化和中央静脉征。我们还回顾了 7T MRI 在研究多发性硬化症患者大脑代谢和功能变化方面的前景。NAIMS 就目前 7T MRI 在多发性硬化症中的应用提供了一系列共识声明,并就今后需要开展哪些工作以加快 7T MRI 在多发性硬化症中的研究以及将该技术应用于临床实践和临床试验提供了指导。这包括技术开发指导、通用采集协议建议以及旨在评估 7T MRI 在改善多发性硬化症诊断、预后和疗效监测方面的实用性的研究建议。NAIMS 希望这篇文章能为未来 7T MRI 在多发性硬化症中的应用提供一个路线图。

The use of 7T MRI in multiple sclerosis: review and consensus statement from the North American Imaging in Multiple Sclerosis Cooperative.

The use of ultra-high-field 7-Tesla (7T) MRI in multiple sclerosis (MS) research has grown significantly over the past two decades. With recent regulatory approvals of 7T scanners for clinical use in 2017 and 2020, the use of this technology for routine care is poised to continue to increase in the coming years. In this context, the North American Imaging in MS Cooperative (NAIMS) convened a workshop in February 2023 to review the previous and current use of 7T technology for MS research and potential future research and clinical applications. In this workshop, experts were tasked with reviewing the current literature and proposing a series of consensus statements, which were reviewed and approved by the NAIMS. In this review and consensus paper, we provide background on the use of 7T MRI in MS research, highlighting this technology's promise for identification and quantification of aspects of MS pathology that are more difficult to visualize with lower-field MRI, such as grey matter lesions, paramagnetic rim lesions, leptomeningeal enhancement and the central vein sign. We also review the promise of 7T MRI to study metabolic and functional changes to the brain in MS. The NAIMS provides a series of consensus statements regarding what is currently known about the use of 7T MRI in MS, and additional statements intended to provide guidance as to what work is necessary going forward to accelerate 7T MRI research in MS and translate this technology for use in clinical practice and clinical trials. This includes guidance on technical development, proposals for a universal acquisition protocol and suggestions for research geared towards assessing the utility of 7T MRI to improve MS diagnostics, prognostics and therapeutic efficacy monitoring. The NAIMS expects that this article will provide a roadmap for future use of 7T MRI in MS.
