Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

4.9K
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...

科学领域:

  • 神经成像是一种神经成像.
  • 精神病学是一个精神病学.
  • 数据科学数据科学数据科学

背景情况:

  • 对于精神分裂症和精神病的结构磁共振成像 (MRI) 研究,由于样本规模较小和方法不同,结果不一致.
  • 以前的多中心倡议已经推动了这一领域的发展,但往往专注于有限的疾病阶段,患者异质性,缺乏全球代表性.
  • 访问现有的神经成像数据集经常受到限制,特别是低收入国家的研究人员.

研究的目的:

  • 建立一个开放式访问平台,在多个全球站点共享结构性MRI数据,包括全球南方.
  • 通过提供统一的数据与丰富的相关临床信息来促进精神病中的综合神经解剖学标记研究.
  • 促进对神经成像数据的公平获取,并促进全球精神病研究能力建设.

主要方法:

  • 精神病MRI共享数据资源 (Psy-ShareD) 将从多个国际网站汇总先前存在的结构T1加权MRI数据.
  • 数据将使用先进技术进行协调,并以图像和功能级格式提供.
  • 相关的人口,诊断,症状,药物,认知和智商数据将与MRI扫描联系起来.

主要成果:

  • Psy-ShareD将提供免费访问用于精神病研究的结构性MRI数据的大型,协调和全球代表性的集合.
  • 该资源将通过将神经成像数据与全面的临床和认知措施联系起来,实现详细的子组和维度分析.
  • 该平台旨在显著提高神经成像研究在精神病障碍的范围和包容性.

结论:

  • 通过提供开放,全球和协调的数据,Psy-ShareD解决了精神病神经成像研究的关键局限性.
  • 这一举措将使研究人员,特别是职业生涯早期的科学家和代表性不足的地区的科学家能够进行先进的分析.
  • 该项目积极寻找合作者来扩大数据集,并促进一个更具包容性和生产力的研究社区.
