Hepatocellular carcinoma treatment response: Imaging findings and criteria

Imaging plays a crucial role in the evaluation of hepatocellular carcinoma (HCC) treatment response. Contrast enhanced computed tomography and magnetic resonance imaging with extra-cellular or hepatobiliary contrast agents are the imaging techniques of choice. Contrast enhanced ultrasound is a promising technique. In this paper, we describe radiological techniques, imaging findings after HCC treatment, and the criteria of response evaluation. The utility of the structured report is also evaluated.
