What do the tumors look like on follow-up CT scans?
During RFA, we ablate the tumor and a margin of normal tissue surrounding the tumor to insure the entire tumor is ablated. We obtain a one week CT scan to evaluate the ablated lesion. The tumor area appears larger than on the pre-operative CT scan. This is a successful ablation. In the later CT scans this lesion shrinks in size and shows no blood flow. These are our criterias for a treatment success.
