核医学进行脑血流定量的方法很多 ,主要包括采血法和非采血法两类 ,其中采血法因为有创且方法较繁复而难以常规开展。本研究中建立了两种非采血的脑血流定量方法 ,即计算机仿真技术脑血流定量方法和颈动脉计数脑血流定量方法并讨论两种方法的结果的可靠性和相互关系。1 材料和
There are many ways to quantify cerebral blood flow in nuclear medicine, including blood collection methods and non-blood collection methods. Among them, the blood collection method is difficult to carry out routinely due to its invasiveness and complicated methods. In this study, we established two non-blood-collecting methods for quantitative determination of cerebral blood flow: computer simulation of cerebral blood flow quantitative method and carotid artery count of cerebral blood flow quantitative methods and discussed the reliability and interrelationship between the two methods. 1 material and
