本文建立了肝血流动力学模型 ,通过回归分析 ,使得肝血流的拟合曲线与实际肝血流灌注的时间 -放射性曲线达到最佳近似 ,从而定量地计算出肝动脉与门静脉的分流指数 ,结果较好。 In this paper, a model of hepatic hemodynamics was established. Through regression analysis, the fitting curve of hepatic blood flow and the time-radiation curve of hepatic perfusion can be best approximated, and the shunt index of hepatic artery and portal vein can be calculated quantitatively , The result is better.
