Objective To investigate the feasibility of our new found 3-dimensional contrast-enhanced ultrasound 3D-CEUS registration system as an early assessment of the therapeutic response to radio frequency ablation for liver cancer Methods Twenty-seven patients with 28 lesions accepted 3D-CEUS before and after radio frequency ablation RFA the therapeutic respond to which would be assessed with 3D-CEUS registration system recording the rate of successful registration The CT was considered as the reference standard Results Ten cases 35 7% were successful matched with auto-registration and 24 cases 85 7% were succesful matched with interactive-registration relatively All cases were considered as complete ablated which were confirmed by CECT with 100% accuracy There were two cases achieving ablation margins ≥5 mm without local tumor progression LTP and nineteen cases achieving 0 -4 mm ablation margin with 3 LTP 3-month 6-month and 1-year later Conclusions The 3D-CEUS interactive-registration system can easily assess the therapeutic response of RFA in liver cancer immediately with high accuracy.
