摘　　要：目的探讨CT灌注成像对肝细胞型肝癌(HCC)与局灶性结节增生(FNH)的鉴别诊断价值。方法比较14例HCC(A组)、10例FNH(B组)的实性成分的CT灌注值;比较FNH实性成分与远处肝组织CT灌注值;比较HCC实性成分、灶周组织及远处肝组织的CT灌注值。结果 A组的实性部分肝动脉灌注量(hepatic arterial perfusion,HAP)、总肝灌注量(total liver perfusion,TLP)、肝动脉灌注指数(hepatic artery perfusion index,HPI)都低于B组,门静脉灌注量(portal venous perfusion,PVP)高于B组,其中HAP、PVP及HPI存在统计学差异。A组病灶实性部分的HAP、HPI高于灶周、远处肝组织,并存在统计学意义;病灶实性部分的PVP低于灶周、远处肝组织,存在统计学差异。B组中病灶实性部分的HAP、HPI、TLP高于远处肝组织,PVP低于远处肝组织,其中HAP、HPI及PVP存在统计学差异。结论 CT灌注成像对肝癌及局灶性结节增生的诊断及鉴别诊断具有重要临床意义。Objective To investigate the differential diagnosis value of CT perfusion imaging in hepatocellular carcinoma（HCC） and focal nodular hyperplasia（FNH）. Methods Comparison of 14 cases of HCC （group A） and I0 cases of FNH （group B） CT perfusion value of solid part; Comparison of FNH of solid composition and the distant liver tissue CT perfusion value; Comparison of HCC solid component, Lesions surrounding tissue and distant liver tissue CT perfusion value. Results The group A solid part of the hepatic artery perfusion （HAP）, the total amount of liver perfusion （TLP）, hepatic artery perfusion index （HPI） is lower than that of group B, portal venous perfusion （PVP） higher than that of group B, the HAP, PVP and HPI statistical differences. Group A solid lesions component of HAP, HPI above focal weeks, liver tissue in the distance, and there is statistical significance; Solid lesions component of PVP below focal weeks, distant liver tissue, statistical differences. Solid lesions in group B component of HAP, the HPI, TLP is higher than the distant liver tissue, PVP is lower than the distant liver tissue, HAP, HPI and PVP statistical differences among them. Concluson CT perfusion imaging of HCC and FNH of the diagnosis and differential diagnosis has important clinical significance.
