Figure 3. a–d.

LF ablation of a lung metastasis originating from breast carcinoma (10 minutes; 45 W). Image (a) shows the preinterventional aspect of the 0.8 cm large tumor. There are no large blood vessels close to the tumor. Image obtained 24 hours after the ablation (b) shows a narrow ablation zone typical for the system. The ablation margin was 0.8 cm. Image obtained 3 months after ablation (c) shows contraction of the ablation zone. Image obtained 6 months after ablation (d) shows new tumoral growth within the ablation zone (arrow).
