为了阐明肝内周围胆管癌的特征性CT表现，我们仔细分析了16例20例胆管癌的两期动态增量CT扫描。采用动力注射器以2ml /s的速度静脉注射100ml碘化造影剂后进行动态增量CT扫描。CT扫描（8-16片）在开始注射造影剂后45-110 s（早期）和6-7 min（延迟期）完成。在CT上，55%（11 / 20）的肝内周围胆管癌在两期均表现为低密度。大多数肿瘤（80%）在早期表现为低密度，其延迟图像的CT数增加。主要肿瘤直径超过3cm的患者中有69%（11 / 16）出现淋巴结病变。所有肿瘤均呈不规则或模糊。20%（4 / 20）的胆管癌难以与肝细胞癌或血管瘤区分。
To elucidate the characteristic CT findings of intrahepatic peripheral Cholangiocarcinoma, two-phased dynamic incremental CT scans of 20 cholangiocarcinomas in 16 patients were carefully analyzed. Dynamic incremental CT scanning was performed after intravenous administration of 100 ml iodinated contrast medium at a rate of 2 ml/s using a power injector. The CT scans (8–16 sections) were obtained during 45–110 s (early phase) and 6–7 min (delayed phase) after commencement of the injection of the contrast medium. On CT, 55% (11 of 20) of intrahepatic peripheral cholangiocarcinomas appeared hypo-dense in both phases. Most of the tumors (80%) appeared hypodense in the early phase and had increased CT numbers in their delayed images. Lymphadenopathy was observed in 69% (11 of 16) of patients whose main tumors exceeded 3 cm in diameter. All tumors appeared irregular or indistinct. Twenty percent (4 of 20) of the cholangiocarcinomas were difficult to distinguish from hepatocellular carcinomas or hemangiomas.
