目的：探讨640层容积CT 4D-DSA技术评价肝动脉解剖变异及肝癌供血动脉类型的应用价值。方法回顾分析经640层容积CT4D-DSA技术处理的31例拟诊或确诊肝癌患者4D血管图像，并结合横轴位容积图像观察分析。结果除2例图像质量不符合诊断要求外，29例中肝动脉解剖变异MichelsⅠ型21例（79.31%），Ⅸ型6例（20.67%），Michels未描述分型2例（22.22%）；规则性肝动脉供血肝癌18例（75%），其中存在寄生动脉供血3例，变异型肝动脉供血肝癌5例（25%）。动门静脉双供血4例（17.39%）；结论640层容积CT 4D-DSA技术有助于全面评价肝动脉解剖变异及肝癌供血动脉类型。

Objective To explore the value of 640 slices volume CT 4D-DSA technique in evaluating the types of anatomical variations of hepatic arteries and the classification of arterial blood supply of hepatocellular carcinoma. Methods 4D-DSA hepatic angiography data of 31 patients with confirmed or suspected hepatocellular carcinoma underwent the 640-slices volume CT scanning were analysed. The anatomical variations of hepatic arteries and the supply artery of liver cancer were analyzed and classified, combining with the axial imaging. Results Except 2 patients the image quality does not meet the diagnostic requirements, 29 patients were enrolled. The anatomical variations of hepatic arteries includes Michels classification Ⅰtype 21 patients(79.31%),Ⅸ type 6 patients(20.67%), and Michels classification no mentioned 2 patients(22.22%). Regular blood supply of hepatic cancer was seen in 18 patients(75%, including 3 patients with parasitic blood supply), and variant blood supply was observed in 5 patients(25%). Portal vein and hepatic artery blood supply were displayed in 4 hepatocellular carcinoma. Conclusion 640 slices volume CT 4D-DSA technique can obviously display anatomical variations of hepatic arteries and the classification of arterial blood supply of hepatocellular carcinoma.
