概括
针对50-70岁的泰国成年人,使用结构磁共振成像 (MRI) 开发了新的大脑模板. 这些特定人口的模板TH150和TH240显示了与现有的西方和中国模板的解剖学差异,提高了神经成像的准确性.
科学领域:
- 神经成像是一种神经成像.
- 医疗成像医学成像
- 人口特定的神经解剖学
背景情况:
- 全球老年人口的增加需要对阿尔茨海默病等与年龄相关的疾病进行研究.
- 结构磁共振成像 (MRI) 对阿尔茨海默氏症的研究和诊断至关重要.
- 由于解剖学变异,现有的大脑模板对泰国人群不适合,因此需要针对特定人口的模板.
研究的目的:
- 开发结构性MRI大脑模板,适用于50-70岁的认知正常的泰国成年人.
- 解决泰国个人的神经成像研究中非人口特定模板的局限性.
- 在泰国人口中创建可靠的模板,以提高阿尔茨海默病研究和诊断的准确性.
主要方法:
- 开发结构性MRI脑模板,使用泰国50-70岁成年人的3DT1加权扫描.
- 图像处理管道包括偏差场校正,刚性注册和代非刚性注册.
- 为了确保稳定性和一致性,创建了TH150 (单扫描仪) 和TH240 (多扫描仪) 的两个模板.
主要成果:
- 两种高度一致的泰国脑模板TH150和TH240已成功开发出来.
- 泰国模板的空间尺寸与个人的大脑测量几乎相同.
- 与中国和西方模板相比,观察到形态差异,包括较少的灰白质和更多的脑脊液,反映了与年龄相关的变化.
结论:
- 已经为50-70岁的泰国成年人建立了特定人口的结构性MRI脑模板.

Brain Imaging
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
