摘要
近红外光谱(NIRS)是一种新型光学成像技术,可以通过监测血氧饱和度变化间接反映脑血流灌注的自动调节功能及脑激活水平。NIRS在神经危重症监护与脑血管介入治疗中已取得广泛应用。我们回顾了NIRS技术的基本原理和在认知障碍评估领域的应用进展,讨论了该技术与目前常用的功能磁共振成像技术的优劣对比。未来NIRS有望在认知障碍的评估中取得更广泛的应用。
Near-infrared spectroscopy(NIRS)is a new optical imaging technique,which can indirectly reflect the auto-regulation of cerebral blood perfusion and the brain activation by monitoring blood oxygen saturation.This technique has been widely used in neurocritical care in recent years.The basic principle of NIRS and its application in cognitive impairment were reviewed,and the comparison of this technique and functional magnetic resonance imaging which has been commonly used in brain activation assessment was discussed.In the future,NIRS is expected to be more widely used in the field of cognitive impairment assessment.
