为了阐明各种成像方式对小肝癌的可检测性，我们进行了数字减影血管造影、计算机断层动脉门静脉造影和二氧化碳增强超声检查。76例最大直径≤ 2cm的小肝癌患者中，61例同时行数字减影血管造影、CT动脉门静脉造影和超声增强检查。在61例接受所有手术的患者中，数字减影血管造影（DSA）、CT动脉门静脉造影（CTA）和超声增强检查（超声增强）分别发现57.4%（35/61）、75.4%（46/61）和72.1%（44/61）的肝癌特征。其中4例仅经超声增强检查发现肝癌，3例仅经CT动脉门脉造影诊断，2例两者均诊断。除了6个血管瘤结节仅通过血管造影容易诊断外，55个良性肝结节中有4个（7.3%）显示假阳性结果，提示肝细胞癌，无论是CT动脉门静脉造影还是增强超声。总之，CT动脉门脉造影和增强超声可以互补地发现小肝癌，比数字减影血管造影更敏感。（Hepatology 1994;20：82-87.）
To elucidate the detectability of small hepatocellular carcinoma by various imaging modalities, we performed digital subtraction angiography, computed tomographic arterioportography and carbon dioxide‐enhanced ultrasonography. Of 76 patients with a small hepatocellular carcinoma of 2 cm or less in maximum diameter, 61 underwent digital subtraction angiography, computed tomographic arterioportography and enhanced ultrasonography at the same time. Concerning the 61 patients undergoing all the procedures, the characteristics of hepatocellular carcinoma were found in 57.4% (35 of 61) by digital subtraction angiography, 75.4% (46 of 61) by computed tomographic arterioportography and 72.1% (44 of 61) by enhanced ultrasonography. Among them, four hepatocellular carcinomas were detected only by enhanced ultrasonography, three were diagnosed only by computed tomographic arterioportography and two were diagnosed by both of them. Except for six hemangioma nodules that were easily diagnosed only with angiography, four of 55 benign hepatic nodules (7.3%) showed false‐positive findings suggestive of hepatocellular carcinoma with either computed tomographic arterioportography or enhanced ultrasonography. In conclusion, computed tomographic arterioportography and enhanced ultrasonography could complementarily detect a small hepatocellular carcinoma more sensitively than digital subtraction angiography.
