Computed tomography (CT) was used to evaluate 47 cases of hepatocellular carcinoma: it was definite in 37, equivocal in 5 and negative in 5 cases. No specific patterns of CT images were recognized. Pre- and postcontrast scans were necessary because several tumors could only be detected on one or the other scan. CT may reveal the exact extent of tumor and show additional tumors in case of multiple lesions. However, false negative results are possible in isodense or very small tumors.
计算机断层扫描（CT）用于评估47例肝细胞癌患者：结果明确的有37例，不明确的有5例，阴性的有5例。未识别出CT图像的特定模式。由于一些肿瘤仅在增强扫描前或增强扫描后才能被检测到，因此增强扫描前后的扫描都是必要的。CT可以显示肿瘤的确切范围，并且在存在多个病灶的情况下显示额外的肿瘤。然而，等密度或非常小的肿瘤可能会出现假阴性结果。
