1. To overview the current status of imaging evaluation after US-guided radiofrequency ablation (RFA) of liver tumors. 2. To illustrate the role of CT, US, MR imaging in the assessment of results of RFA. 3. To suggest strengths and limitations of various imaging modalities in determining technical success of RFA.
