摘　　要：目的:探讨T2*-PWI在肝细胞癌血流灌注评估中的价值。方法:对21例原发性肝细胞癌患者治疗前行常规扫描,并加扫T2*-PWI检查,比较T2*-PWI肿瘤与正常肝实质的灌注参数。结果:21例患者中,T2*-PWI肿瘤感兴趣区的TIC图像基本表现为迅速下降迅速上升,而正常肝组织的TIC曲线大致表现为缓慢下降缓慢上升。T2*-PWI肿瘤与正常肝实质的各灌注参数均有显著性差异(P<0.05)。结论:T2*-PWI能够反映出肝细胞癌的血流灌注特点;对肝细胞癌有重要的评估价值。Purpose：To explore the potential clinical value of T2＊-weighted perfusion weighted image（T2＊-PWI） in the pre-operation evaluation of hepatocellular carcinoma（HCC）.Methods：Twenty-one patients with hepatocellular carcinoma were performed MRI scans,which including T2＊-PWI,before operation.The perfusion parameters of the hepatic tumor and normal liver tissue were compared.Results：In the 21 patients,the TIC images of tumor showed rapid decline and rapid rise;However,the normal liver parenchyma TIC images showed slow decline and slow rise.Conclusion：T2＊-PWI can reflect the blood perfusion characteristics of hepatocellular carcinoma.T2＊-PWI has important preoperative evaluation value for hepatocellular carcinoma.
