To determine the computed tomographic (CT) and magnetic resonance (MR) imaging appearances of early advanced hepatocellular carcinoma (HCC).
Twenty-seven surgically resected cases of early advanced HCC were studied with CT, CT during arterial portography, CT arteriography, and MR imaging.
The sensitivity of standard CT (unenhanced, early, and late CT combined) for the detection of early advanced HCC was 81%, while that of standard MR imaging (T1- and T2-weighted MR imaging combined) was 83%. A nodule-in-nodule appearance was identified in approximately one-third to one-half of cases. Signal behavior of early and advanced components of early advanced HCC followed the expected behaviors of isolated early HCC and isolated advanced HCC, respectively. Tumor size was accurately estimated with standard CT and standard MR imaging.
More research must be performed to ascertain whether any relationship exists between the different types of HCC and the clinical outcome.
确定早期进展期肝细胞癌（HCC）的计算机断层扫描（CT）和磁共振成像（MR）表现。
对27例手术切除的早期进展期HCC病例进行了CT、动脉门静脉造影CT、CT动脉造影和MR成像研究。
标准CT（平扫、动脉期和延迟期CT联合）检测早期进展期HCC的敏感性为81%，而标准MR成像（T1加权和T2加权MR成像联合）的敏感性为83%。约三分之一至二分之一的病例表现为结节内结节。早期进展期HCC的早期和进展期成分的信号表现分别遵循孤立早期HCC和孤立进展期HCC的预期表现。标准CT和标准MR成像能准确估计肿瘤大小。
必须进行更多研究以确定不同类型的HCC与临床结局之间是否存在任何关系。
