Thirty patients with primary hepatocellular carcinoma were studied by computed tomography (CT) and angiography. Tumor images on CT could be classified into four groups according to the differences between precontrast and postcontrast scans. In comparing the findings of angiography and CT, hypervascular tumor shadows on angiography were visualized as low density areas on CT. However, in several cases, the vessel character of the tumor, hypervascularity, and prolonged capillary staining may have been responsible for the CT tumor appearance after contrast medium administration. The studies of cases with therapeutic embolization of the hepatic artery showed a marked decrease in density on CT. Patients with obstruction of branches of the portal vein had homogeneous low densities in the areas drained by the obstructed branches. Although the characteristics of the hepatic artery played an important role, portal blood flow was as significant in determining equally or more noticeably the CT appearance of hepatocellular carcinoma.
对30例原发性肝细胞癌患者进行了计算机断层扫描（CT）和血管造影研究。根据增强扫描前后的差异，CT上的肿瘤图像可分为四组。在比较血管造影和CT的结果时，血管造影上的高血供肿瘤阴影在CT上显示为低密度区。然而，在一些病例中，肿瘤的血管特征、高血供以及毛细血管染色时间延长可能是造影剂注入后CT上肿瘤表现的原因。对肝动脉治疗性栓塞病例的研究显示，CT上密度显著降低。门静脉分支阻塞的患者，在阻塞分支引流区域有均匀的低密度影。虽然肝动脉的特征起重要作用，但门静脉血流在同等程度或更显著地决定肝细胞癌的CT表现方面同样重要。
