The cross-sectional imaging findings play a crucial role in the diagnosis of hepatocellular carcinoma (HCC). Recent studies have shown that imaging findings of HCC are not only relevant for the diagnosis of HCC, but also for identifying genetic and pathologic characteristics and determining prognosis. Imaging findings such as rim arterial phase hyperenhancement, arterial phase peritumoral hyperenhancement, hepatobiliary phase peritumoral hypointensity, non-smooth tumor margin, low apparent diffusion coefficient, and the LR-M category of the Liver Imaging-Reporting and Data System have been reported to be associated with poor prognosis. In contrast, imaging findings such as enhancing capsule appearance, hepatobiliary phase hyperintensity, and fat in mass have been reported to be associated with a favorable prognosis. Most of these imaging findings were examined in retrospective, single-center studies that were not adequately validated. However, the imaging findings can be applied for deciding the treatment strategy for HCC, if their significance can be confirmed by a large multicenter study. In this literature, we would like to review imaging findings related to the prognosis of HCC as well as their associated clinicopathological characteristics.

Abstract PDF: Background/Aim
s: This study compared the outcomes of patients with small hepatocellular carcinomas (HCCs) who were treated using transarterial chemoembolization (TACE) or radiofrequency ablation (RFA).
Methods
This was a post-hoc analysis of a prospective study that evaluated the diagnostic efficacy of magnetic resonance imaging (MRI) and computed tomography (CT). We analyzed 41 small hepatic nodules in 32 patients that showed typical radiologic hallmarks on both CT and gadoxate-enhanced MRI (typical nodules) and 25 small hepatic nodules from 22 patients that showed atypical radiologic hallmarks on CT and typical radiologic hallmarks on MRI (discrepant nodules).
Results
There were no significant differences in the baseline characteristics of the patients with typical and discrepant nodules. Complete response rates 1 month after TACE or RFA were 75.0% (18/24) and 94.1% (16/17; P=0.20), respectively, for the patients with typical nodules and 58.8% (10/17) and 100% (8/8; P=0.05), respectively, for the patients with discrepant nodules. Treatment failure rates after TACE or RFA were 33.3% (8/24) and 5.8% (1/17; P=0.15), respectively, for the patients with typical nodules and 47.0% (8/17) and 0.0% (0/8; P=0.02), respectively, for the patients with discrepant nodules. Among patients achieving complete response, there were no significant differences in the risk of marginal recurrence.
Conclusions
RFA provided higher complete response rates and significantly lower treatment failure rates than TACE for patients with discrepant nodules of HCC. Therefore, a treatment modality such as RFA may be preferable for small HCCs which show discrepancy on two imaging modalities.
