本文报告14例原发性肝癌（HCC）患者在动脉门脉造影（CTAP）时及碘油动脉注射后CT检查结果。主要病变和相关的子结节或肝内转移瘤的可检测性进行了评估。所有14例患者随后均行肝切除术。通过逐病灶分析，将影像学检查结果与手术和病理结果进行比较。在切除的标本中，共发现34个肿块：18个主要肿瘤肿块和16个肝内转移瘤。CTAP对主要肿瘤的检出率为94%，碘化油CT为82%。然而，这两种技术的子结节检出率都很低，CTAP仅为38%，而碘化油CT为50%。尽管这两种技术仍然是HCC患者重要的术前成像方法，但本研究结果表明，小的子结节（
Fourteen patients with hepatocellular carcinoma (HCC) were examined with computed tomography (CT) during arterial portography (CTAP) and with CT after intraarterial injection of iodized oil. The detectability of main lesions and associated daughter nodules or intrahepatic metastases was assessed. Hepatic resection was subsequently performed in all 14 patients. The results of the imaging studies were compared with the surgical and pathologic findings by means of a lesion-by-lesion analysis. A total of 34 masses were identified in the resected specimens: 18 main tumor masses and 16 intrahepatic metastases. For CTAP, the detection rate of main tumors was 94%; for iodized-oil CT, 82%. However, the daughter-nodule detection rates for both techniques were poor-only 38% detected for CTAP and 50% for iodized-oil CT. Although these two techniques remain important preoperative imaging methods in patients with HCC, the results of this study suggest that small daughter nodules (
