Cryoablation in the liver. a The axial PET-CT image shows a subcapsular FDG-avid lesion (white arrow). The patient had previously undergone surgery for cholangiocarcinoma, and the biopsy showed the lesion to be metastatic cholangiocarcinoma. b Cryoablation was performed under US and cone-beam CT guidance, which shows the iceball (arrowheads) produced by two cryoneedles covering the lesion. Another needle (black arrow) was also inserted for fluid injection to separate the adjacent transverse colon from the tumour. c One year later, the control PET-CT image shows complete metabolic response in place of the lesion
