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.
