摘　　要：目的初步探讨基于PC机的CT肝脏灌注成像和定量测量方法的可行性。方法以10例行肝脏动态增强扫描的患者为研究对象,合理建立双输入单隔室模型,通过去卷积运算,获得肝脏灌注参数,并绘出肝脏灌注图像。结果基于PC机的肝脏灌注成像和定量测量可真实反映肝组织血流灌注量的变化。结论基于PC机的CT肝脏灌注成像和定量测量方法的初步研究有临床应用价值。Objective： To determine the feasibility of liver CT perfusion mapping and quantitative measurement programs for PC. Methods：Ten patients underwent dynamic contrast enhanced liver CT. A dual-input one-compartment model of blood flow was established to compute related parameters of liver hemodynamics and draw the CT perfusion images through deconvolution. Results：The liver CT perfusion mapping and quantitative measurement programs for PC reflected the changes in liver tissue perfusion amount and figured out the related parameters of liver hemodynamics. Conclusion： This study based on the idea of computer aided diagnosis is worth being used in clinical practice.
