The aim of diagnosis imaging is to detect hepatocellular carcinoma at an early stage, when a curative treatment is available. Biopsy is no longer required prior to treatment, and diagnosis of hepatocellular carcinoma is heavily dependent of imaging characteristics. Therefore, the purpose of this article is to describe the typical features of small (<20mm) and larger hepatocellular carcinomas with noninvasive diagnostic criteria, including ultrasound, computed tomography and MRI. Advances in these imaging modalities have greatly improved the detection of small hepatic nodules on liver cirrhosis, including the different steps of carcinogenesis, from regenerative to dysplastic nodules, and we emphasize the difficulties of radiological differentiation of precancerous lesions and small hepatocellular carcinomas.
诊断成像的目的是在有治愈性治疗方法时早期检测肝细胞癌。治疗前不再需要活检,肝细胞癌的诊断在很大程度上依赖于成像特征。因此,本文的目的是描述小(<20mm)和较大肝细胞癌的典型特征以及无创诊断标准,包括超声、计算机断层扫描和磁共振成像。这些成像方式的进展极大地提高了对肝硬化肝脏上小肝结节的检测,包括从再生结节到发育异常结节的癌变不同阶段,并且我们强调癌前病变和小肝细胞癌的放射学鉴别困难。
