摘要目的采用动态容积灌注CT测量足部血流量的方法应用于动物实验和人体研究,验证其可行性。材料与方法人体研究经伦理委员会批准,所有病人均签署知情同意书。动物研究由动物管理及使用委员会批准。首先采用家兔进行灌注成像。基于斜率法的灌注分析软件构建出有颜色代码的 Abstract Objective To evaluate the feasibility of using dynamic volumetric perfusion CT to measure foot blood flow in animal experiments and human studies. Materials and Methods Human studies were approved by the Ethics Committee and all patients signed informed consent. Animal studies approved by the Animal Management and Use Committee. First, rabbits were used for perfusion imaging. The perfusion analysis software based on the slope method constructs a color code
