【摘要】 目的:探讨多层螺旋CT血管造影技术(MSCTA)对肝癌(HCC)与肝静脉和门静脉的相关性,及对HCC的诊断和鉴别诊断价值。方法:对病理证实或临床及实验室检查确诊、未经治疗的HCC患者120例进行全肝螺旋CT平扫及静脉期增强扫描,通过图像工作站获得静脉期CT血管造影图像,观察肿瘤与静脉血管的关系。结果:120例HCC中5例(4.2%)病灶与门静脉相关、2例(1.7%)病灶与肝静脉相关、113例(94.1%)病灶与门静脉及肝静脉双重相关,后者构成比最大。结论:绝大多数HCC病灶与门静脉及肝静脉具有双重相关性;此特征对HCC与肝局灶性结节增生的鉴别诊断具有重要价值,对HCC定性诊断及HCC与其他类型富血供肿物的鉴别诊断价值尚不明确。更多还原

【Abstract】 Objective:To study the correlation between intrahepatic vein and hepatocellular carcinoma(HCC) using Multislice CT Angiography, and to evaluate its diagnosis and differential diagnosis value.Methods: 120 patients with HCC proved by histopathology or diagnosed by clinical and laboratory examination were included before receiving treatment, unenhanced and venous-phase enhanced helical CT scans were performed in the entire liver, and the obtained data were sent to workstation to reconstruct the images of vein, the relationship was observed between intrahepatic vein and hepatocellular carcinoma.Results: 5(4.2%) of 120 HCC correlated with the portal vein, 2(1.7%) correlated with the hepatic vein, 113(94.1%) correlated with both the portal vein and the hepatic vein, the constituent ratio of the last is the highest in 120 cases.Conclusion: Most of HCC correlated with both portal vein and hepatic vein, this feature is of great value in differentiating HCC from focal nodular hyperplasia, but of uncertain value in accurate diagnosis and differential diagnosis of HCC from other hypervascular hepatic masses.更多还原
