1 Fig. 6. RF ablation with high-power protocol and perpendicular access
Fig. 6. RF ablation with high-power protocol and perpendicular access.A, B. Pre- and post-RF ablation CT images. Post-RF ablation CT image (B) reveals contrast leak on hepatic surface after RF ablation, compared to that observed on pre-RF ablation CT image (A)(arrow). C. Liver specimen corresponding to CT images. Analysis of specimen reveals contrast leak on hepatic surface (arrowheads). D. Another liver specimen with low-power protocol and perpendicular access. Analysis of specimen reveals no contrast leak on hepatic surface, and diameter of ablation zone just beneath capsule is larger than that of specimen shown in (C)(double-headed arrows on C, D) (Scale bar: 5 cm). Fig. 6. RF ablation with high-power protocol and perpendicular access.A, B. Pre- and post-RF ablation CT images. Post-RF ablation CT image (B) reveals contrast leak on hepatic surface after RF ablation, compared to that observed on pre-RF ablation CT image (A)(arrow). C. Liver specimen… Korean J Radiol Apr;20(4):
