通过影像学手段在一定程度来直观显示活体器官、组织的血流动力学状态和功能情况的灌注过程并进行定量或半定量分析的方法称为灌注成像。目前应用多排螺旋CT结合计算机图像后处理技术可快速、准确、无创、三维地评价组织器官微循环内血流动力学变化,成功实现了肝脏的CT灌注成像
Imaging methods to some extent to visualize living organs, tissue hemodynamic status and functional perfusion process and quantitative or semi-quantitative analysis of the method known as perfusion imaging. Currently using multi-slice spiral CT combined with computer image post-processing technology can be rapid, accurate, noninvasive, three-dimensional evaluation of tissue and organ microcirculation hemodynamic changes, the successful realization of the liver CT perfusion imaging
