概括

多发性硬化症 (MS) 病变扩张受到静脉和白质道的影响,但不是贝克萨罗. 表面因子促进了雷米林化,这表明MS组织修复的多方面的治疗点.

科学领域:

神经科学是一个神经科学.
免疫学免疫学免疫学
放射学放射学是一门学科.

背景情况:

多发性硬化症 (MS) 是一种慢性炎症性疾病,其特点是白质 (WM) 病变.
了解病变扩张,收缩和复髓化的病理机制对于开发有效的MS疗法至关重要.

研究的目的:

研究驱动白质病理机制的病变动态 (扩张/收缩) 和多发性硬化症 (MS) 中的复髓化.
评估损伤方向相对于WM通道,静脉和表面入梯度对这些过程的影响.
评估贝克萨罗对病变扩张/收缩和复髓化的影响.

主要方法:

从CCMR-One贝克沙罗试验中分析了49名复发性复发性多发性硬化症患者的1,613个病变.
测量损伤方向相对于WM通道,表面入梯度和静脉.
通过6个月的雅科比变形和通过磁化转移比率 (MTR) 成像的再髓化来评估病变扩张.

主要成果:

当与基线上的面入梯度和静脉对齐时,损伤体积较小.
损伤的扩张和收缩受到相对于WM通道和静脉的方向的影响.
贝克萨罗没有影响病变的扩张或收缩,但在与表面入梯度和静脉对齐的病变中,MTR显著增加,这表明了复髓化.

结论:

静脉和WM通道因素调节MS病变的扩张和收缩.
贝克萨罗的复效应与表面的因素有关,而不是病变扩张的动态.
针对多种病理过程,包括静脉/WM通道的影响和表面因素,可能是限制病变扩张和促进MS组织修复的必要条件.

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...
