Fig. 1C48-year-old woman. Enhanced CT scan 1 month after
radiofrequency ablation shows large zone of ablation (arrow)
encompassing tumor and margin of normal liver.
Fig. 2A80-year-old woman with 5.3-cm hepatic metastatic lesion from
ovarian cancer. Unenhanced CT scan at radiofrequency ablation shows large
liver tumor (arrow) from ovarian cancer.
Fig. 2C80-year-old woman with 5.3-cm hepatic metastatic lesion from
ovarian cancer. Enhanced CT scan 9 months after radiofrequency ablation shows
involution of zone of ablation (arrow).
Fig. 2D80-year-old woman with 5.3-cm hepatic metastatic lesion from
ovarian cancer. Enhanced CT scan 9 months after radiofrequency ablation along
caudal aspect of zone of ablation (arrow) shows that this area is
slightly denser, raising possibility of enhancement versus volume-averaging
artifact.
Fig. 2E80-year-old woman with 5.3-cm hepatic metastatic lesion from
ovarian cancer. FDG PET scan shows area in question (arrow) is FDG
avid and represents recurrent tumor.
Fig. 2F80-year-old woman with 5.3-cm hepatic metastatic lesion from
ovarian cancer. FDG PET scan after second ablation session shows absence of
uptake in zone of ablation (arrow), confirming complete
treatment.
Fig. 2G80-year-old woman with 5.3-cm hepatic metastatic lesion from
ovarian cancer. Enhanced CT scan 1 year after second ablation shows stable
zone of ablation (arrow).
