摘　　要：MR灌注成像主要通过测量血流动力学参数来反映组织血流灌注及微血管渗透情况。根据其成像原理不同分为动态磁敏感对比增强MRI(DSC-MRI)、动态对比增强MRI(DCE-MRI)和动脉自旋标记(ASL)灌注成像。这些方法各有优缺点,就MR灌注成像的基本原理及其在脑胶质瘤中的研究进展进行综述。MR perfusion weighted imaging could evaluate tissue blood perfusion and microvascular permeability by measuring different parameters. According to the different imaging principles, the techniques could be classified into dynamic susceptibility contrast MRI （DSC-MRI）, dynamic contrast-enhanced MRI （DCE-MRI）, and arterial spin labeling perfusion weighted imaging （ASL-PWI）. Each technique has its advantages and disadvantages. In this review we summarized the basic principles and applications of PWI in glioma.
