FDG uptake in a PET/CT one month after image-guided percutaneous lung ablation. a PET-CT acquired after one month of percutaneous lung MWA, showing a growth of the ablative area compared to the pre-treatment CT (Fig. 7-A). It also presented a subtle uptake of FDG within the treated area (arrow). Given the proximity of the treatment, this is probably due to an inflammatory reaction. We also observe a residual scar due to a past probe-path-related lung hemorrhage reported (triangle). b–d We observed a progressive reduction in the size of the ablative area after 3 (b), 6 (c), and 12 months (d) of treatment, finally observing a residual scar (arrows)
