Abstract

For hepatocelluar carcinoma(HCC), there are several treatment options such as transcatheter arterial chemoembolization (TACE), radiofrequency ablation (RFA), and radiation therapy. It is essential to be familiar with the radiologic findings to know whether the residual or recurrent tumor exist after treatment. But, radiological image findings show complex responses according to the initial tumor morphology and treatment methods. One purpose of this article is to discuss the guidelines to evaluate the tumor response of HCC after treatment. And the other purpose is to evaluate the imaging features of HCC after various treatment
methods
and to reveal the limitations of each imaging technique in evaluating the therapeutic effect on HCC.
