At the early onset of the 20th century, several studies already reported that the gray matter was implicated in the histopathology of multiple sclerosis (MS). However, as white matter pathology long received predominant attention in this disease, and histological staining techniques for detecting myelin in the gray matter were suboptimal, it was not until the beginning of the 21st century that the true extent and importance of gray matter pathology in MS was finally recognized. Gray matter damage was shown to be frequent and extensive, and more pronounced in the progressive disease phases. Several studies subsequently demonstrated that the histopathology of gray matter lesions differs from that of white matter lesions. Unfortunately, imaging of pathology in gray matter structures proved to be difficult, especially when using conventional magnetic resonance imaging (MRI) techniques. However, with the recent introduction of several more advanced MRI techniques, the detection of cortical and subcortical damage in MS has considerably improved. This has important consequences for studying the clinical correlates of gray matter damage. In this review, we provide an overview of what has been learned about imaging of gray matter damage in MS, and offer a brief perspective with regards to future developments in this field.
在 20 世纪初,已有几项研究报道称灰质参与了多发性硬化症(MS)的组织病理学。然而,由于白质病理学在该病中一直受到主要关注,且用于检测灰质髓鞘的组织学染色技术并不理想,直到 21 世纪初,MS 中灰质病理学的真正程度和重要性才最终得到认识。研究表明,灰质损伤频繁且广泛,在进行性疾病阶段更为明显。随后的几项研究表明,灰质病变的组织病理学与白质病变不同。不幸的是,对灰质结构的病理学成像证明很困难,特别是使用常规磁共振成像(MRI)技术时。然而,随着最近引入了几种更先进的 MRI 技术,MS 中皮质和皮质下损伤的检测得到了极大改善。这对研究灰质损伤的临床相关性有重要影响。在本文综述中,我们概述了在 MS 中关于灰质损伤成像的研究成果,并对该领域的未来发展提供了简要展望。
