Summary
Brief summary (as posted)
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.

Arms and outcomes
Arms (1)
- type
- OTHER
- label
- CT/US fusion
- description
- patients undergo routine conventional feasibility planning ultrasound, and clinical decision of RFA feasibility is made based on conventional planning ultrasound. Then additional planning ultrasound using CT/US fusion technique is immediately performed by the same operator, and clinical decision is made based on fusion imaging.
- interventionNames
- Device: CT/US fusion
Primary outcomes (1)
- measure
- RFA feasibility rates on planning USG with/without fusion CT/MR and US
- timeFrame
- 10 minutes after finishing planning USG
- description
- comparison of rates of RFA feasibility on conventional planning USG and on fusion planning USG
Secondary outcomes (2)
- measure
- Rate of tumor visibility on planning USG with/without fusion technique
