Fig. 1A61-year-old woman with solitary left kidney. Axial unenhanced
CT image shows placement of radiofrequency ablation probe within left renal
mass.
Fig. 1B61-year-old woman with solitary left kidney. Axial
T2-weighted MR images without (B) and with (C) fat saturation
obtained 2 months after tumor ablation show typical appearance of a treated
tumor with low signal within ablation zone. Signal of ablated tumor
approximates signal of surrounding fat on fat-saturated image.
Contrast-enhanced images (not shown) revealed no evidence of enhancement
[2].

Fig. 2Creatinine clearance after radiofrequency ablation. Graph
shows long-term follow-up results for 12 patients. Because of variable
follow-up periods for this group, data analysis was performed on findings at
1-month follow-up visit.
