16层螺旋CT灌注成像在原发性肝癌中的应用

Application of CT perfusion in primary hepatocellular carcinoma

目的:探讨肝癌内部CT灌注特点及CT灌注成像在肝癌诊治中的应用价值。方法:对16例原发性肝癌共16个病灶的CT灌注参数进行分析。结果:灌注图像更真实显示病灶边缘。肝癌病灶中心BF、BV、HAP明显高于病灶边缘,MTT较边缘短,PS较边缘略低。结论:CT灌注成像对肝癌诊断及疗效评估、监测肿瘤复发方面具有重要价值。

Objective： To discuss the character and value of CT perfusion imaging in primary hepatocellular carcinoma with multislice helical CT. Methods： The parameters of 16 primary hepatocellular carcinoma focus confirmed by clinic were analyzed. Results： In CT perfusion images the boundary of tumors displayed more clearly. And the average parameter value of BF, BV, HAP in center focus is higher than the edge, but MTY was shorter and PS was a little lower than at the edge. Conclusion： CT perfusion imaging has significant value in diagnosing, inspecting curative effect and recrudescence of primary hepatocellular carcinoma.
