目的：分析多层螺旋CT（ MSCT）灌注成像下肝癌结节血流动力学的改变。方法对98例肝癌患者进行MSCT灌注扫描，分析肝癌结节血流动力学改变情况。结果正常组织、肝癌结节、交界处HBF、HPI、HPP、HAP、HBV值比较具有明显差异（P＜0．05）；三者TTP及PEI值比较具有明显差异（P＜0．05）；大结节病灶中心、交界内1 cm、交界处、交界外1 cm及正常组织HBF、HPI、HPP、HAP、HBV、TTP、PEI比较呈现明显差异（P＜0．05）。结论 MSCT灌注成像可以清楚反应肝癌结节附近血流动力学改变情况，值得临床推广。

Objective To study the hemodynamic changes in liver nodules under multi-slice spiral CT (MSCT) perfu-sion imaging .Methods 98 cases of liver cancer patients received MSCT perfusion scan ,and hemodynamic changes in liver nod-ules were studied.Results HBF,HPI,HPP,HAP and HBV in normal tissue,liver nodules,and junction area had significant difference (P<0.05);TTP and PEI values of the 3 groups had significant difference (P<0.05);HBF,HPI,HPP,HAP,HBV, TTP and PEI in larger nodules center ,1 cm inside the junction area ,junction area,cross area,1 cm outside the cross area and nor-mal tissues had significant differences (P<0.05).Conclusion MSCT perfusion imaging can clearly show hemodynamic chan-ges in liver nodules ,and it is worthy of clinical promotion .
