A method of blood flow measurement is described that determines flow through a particular artery in absolute units or as a fraction of the cardiac output. For measuring flow as a percentage of cardiac output, no assumption about the vessel's cross-sectional shape is necessary. If one assumes that the vessel's cross section is circular, then absolute flow determination is possible. All methods would require only a single intravenous injection of contrast material. Details of the theory of these methods are presented and alternative data analysis options are developed and discussed.
本文描述了一种血流测量方法，该方法可确定通过特定动脉的血流，单位为绝对流量或作为心输出量的一部分。对于将血流测量为心输出量的百分比，无需对血管的横截面形状进行假设。如果假设血管的横截面是圆形的，那么就可以确定绝对流量。所有方法仅需单次静脉注射造影剂。文中介绍了这些方法的理论细节，并开发和讨论了替代数据分析选项。
