Figure 5

Post-mortem findings of different ballistic markers created in pig liver. a), b) The liver was freshly cut at Day 7, while the marker was created either with injected methylene blue (a) or without methylene blue injection (b). c), d) Macroscopic illustration of the ballistic marker after 3 weeks of formalin fixation. The RF lesions correspond to spheroid areas of ablation surrounded by healthy tissue in frames a) -c). The RF ablation shown in frame d) was performed at the liver periphery and corresponds exactly with the microscopic histology, illustrated in frame e) (see embedded distance scale). The FOV shown in frames a) - c) is 15 × 15 mm and in frame d) is 15 × 20 mm.
