为了帮助区分结直肠癌肝转移和肝细胞癌，比较了造影剂给药后5分钟以上进行的计算机断层扫描（CT）（“晚期增强CT扫描”）和病理结果。转移性腺癌的晚期增强CT扫描显示与存活肿瘤相对应的外周低密度区（PLDA）和代表纤维结缔组织的中心高密度区。这种现象在20例转移性腺癌患者中的15例（75%）和50例肝细胞癌患者中的1例（2%）中被发现。晚期增强CT扫描可能有助于鉴别转移性非粘液性结直肠癌和肝细胞癌。
To aid in the distinction between colorectal cancer metastasis to the liver and hepatocellular carcinoma, findings on computed tomographic (CT) scans taken more than 5 minutes after contrast material administration ("late-enhanced CT scans") and pathologic findings were compared. Late-enhanced CT scans of metastatic adenocarcinoma showed a peripheral low-density area (PLDA) that corresponded to viable tumor and a central high-density area that represented fibrous connective tissue. This phenomenon was recognized in 15 of 20 (75%) patients with metastatic adenocarcinoma and in one of 50 (2%) patients with hepatocellular carcinoma. Late-enhanced CT scans may be useful in distinguishing between metastatic nonmucinous colorectal cancer and hepatocellular carcinoma.
