Brain Imaging

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...

背景情况:

结构性MRI的测量误差限制了检测群体差异和大脑形态学纵向变化的统计能力.
加速的T1加权MRI扫描 (约1分钟) 提供与传统的较长扫描相比的形态测量误差.

结论:

用加速MRI进行集群扫描可以显著提高形态测量精度.
这种方法提高了检测群体差异和纵向变化的统计能力.
集群扫描有可能开发出更敏感的疾病进展生物标志物.
