BRAIN IMAGING

各种临床成像方法被用于研究体内的大脑。 这些技术能够比较大体解剖结构（CAT计算轴向 断层摄影术，MRI -磁共振成像）的大脑与电 活动（EEG -脑电图; ERP-事件相关电位）和 特定区域中葡萄糖利用率（PET正电子发射 断层扫描）。从临床的角度来看，这些技术， 与其他诊断测试，使定性判断作出， 大脑的解剖和生理完整性为了 定量分析图像数据，成像技术本身是 正在调查，以及相关的数学的影响， 模型和主观输入对大脑图像重建的影响。 此外，用于评估和关联的数学和统计方法 正在开发多变量数据的这些各种来源。

Various clinical imaging methods are being used to study the brain in vivo. These techniques enable comparisons of gross anatomy (CAT-Computed Axial Tomography, MRI - Magnetic Resonance Imaging) of the brain with electrical activity (EEG - electroencephalography; ERPs-Event-Related Potentials) and rate of glucose utilization in a specific regions (PET Positron Emission Tomography). From a clinical perspective, these techniques, in association with other diagnostic tests, enable qualitative judgments to be made as to the anatomic and physiologic integrity of the brain. In order to quantitatively analyze image data, the imaging techniques themselves are being investigated, as well as the effects of the associated mathematical models and subjective inputs on the reconstruction of the brain image. Moreover, mathematical and statistical methods for evaluating and relating these various sources of multivariate data are being developed.
