对近红外光谱大脑拓扑图技术的成像原理进行了探讨 ,并对大鼠大脑光敏剂诱导梗塞模型的皮层缺血部位进行定位成像。分别用NIRS拓扑仪、磁共振成像和解剖样本染色 ,对 10只SD雄性大鼠大脑皮层缺血部位进行成像。结果表明 ,NIRS拓扑图所显示的皮层缺血面积与磁共振图象及解剖样本显示的皮层缺血面积的相关系数分别为 0 87(p <0 0 5 )和 0 81(p <0 0 1)。
The imaging principle of near infrared spectroscopy brain topography was discussed, and the imaging and imaging of cortical ischemia in rat brain photosensitizer-induced infarction model was carried out. NIRS topographs, magnetic resonance imaging and anatomical samples were used to stain the cerebral cortex of 10 male SD rats. The results showed that the correlation coefficient between ischemic area of ischemic cortex and magnetic resonance imaging and cortical ischemic area showed by NIRS topography were 0 87 (p 0 05) and 0 81 (p 0 01, respectively) ).
