Current brain imaging techniques, such as computed tomography (CT) and magnetic resonance imaging (MRI), provide noninvasive, high-resolution images that depict fine anatomic structure and delineate pathology by control of image contrast and sensitivity to the physicochemical microenvironment. These methods, although invaluable for the identification, characterization, and localization of lesions, do not provide any assessment of the functional viability of brain tissues, nor of the spatial organization of sensory, motor, and cognitive systems. However, such additional functional information is of great significance to the clinician in the determination of treatment strategies and patient management.
当前的脑成像技术,如计算机断层扫描(CT)和磁共振成像(MRI),能够提供无创的高分辨率图像,通过控制图像对比度和对物理化学微环境的敏感性来描绘精细的解剖结构并勾勒出病变情况。这些方法虽然对于病变的识别、特征描述和定位非常宝贵,但并不能对脑组织的功能活力或感觉、运动和认知系统的空间组织进行任何评估。然而,这种额外的功能信息对于临床医生确定治疗策略和患者管理具有重要意义。
