About
The purpose of this study is to determine whether fusion technique of pre-radiofrequency ablation (RFA) cross-sectional imaging (CT or MR) and real-time ultrasonography would improve feasibility of RFA in patients with liver tumor in comparison with ultrasonography guidance alone.
Full description
RFA is one of commonly used local therapies for primary or secondary liver tumors. For successful and safe procedure, safe route of electrode and lesion visibility are essential for RFA, and the conditions are usually evaluated on pre-RFA planning ultrasonography (USG). However, RFA is sometimes aborted due to limited sonic window of various cause and challenging identification of small isoechoic tumors or hepatocellular carcinomas among dysplastic nodules . Therefore, precise targeting and assuring safe route would be of clinical importance. In this preliminary study, investigators attempted to determine US and CT/MR fusion technique would be able to improve RFA feasibility in patients with liver tumors in comparison with conventional US alone technique.
