- 大脑研究 大脑研究
背景情况:
- 慢性偏头痛 (CM) 与药物过度使用头痛 (MOH) 呈现出明显的神经生物学变化.
- 以前使用单一成像模式的研究产生了不一致的结果.
- 多模式核磁共振 (MRI) 对于在有或没有MOH的情况下描述CM中的大脑变化至关重要.
研究的目的:
- 用多式核磁共振成像 (MRI) 来表征CM患者和没有MOH患者的脑部异常.
- 调查急性止痛药使用频率与大脑变化之间的关系.
- 为了区分CM患者和没有MOH的CM患者之间的神经生物学概况.
主要方法:

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...
