概括

在患有多发性硬化症 (MS) 患者中,高级神经影像显示了大脑结构上的差异. 特别是观察到白体积的减少,这表明MS疼痛的潜在放射性相关性.

科学领域:

神经成像
神经学
治疗疼痛的方法

背景情况:

之前对多发性硬化症 (MS) 疼痛的研究依赖于结构性MRI和描述性方法.
多发性硬化症疼痛的解剖相关性需要客观和先进的分析技术.

研究的目的:

在MS患者中确定神经病痛的放射性相关性.
使用客观的大脑MRI细分和分析来评估疼痛.

主要方法:

探索性试点研究比较MS患者有疼痛 (n=8),MS患者没有疼痛 (n=11) 和小纤维神经病变 (SFN) 患者 (n=6).
使用激光唤起潜能 (LEPs) 证实了神经病痛.
用自动细分 (SAMSEG,SynthSEG) 和扩散张力成像进行的大脑MRI;在MS患者中进行脊柱MRI.

主要成果:

SynthSeg的分析显示,与没有疼痛的MS患者相比,右白体体积减少.
扩散张力成像显示了外部囊,内部囊,后部乳头辐射和上部纵向囊的显著差异.
两组之间没有发现脊髓损伤负荷的显著差异.

结论:

先进的神经影像技术在识别多发性硬化症中神经病痛的相关性方面显示出前景.
需要使用更大的样本进行进一步验证以确认这些发现.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
