The safety and effectiveness of percutaneous
image-guided ablations can be improved if the procedure
could be assessed quantitatively. Using MRIs ability to
depict both the tumor and the iceball during
cryoablations, we developed a novel computerized tool
that utilized fast automatic segmentation and
registration methods to compute ablation metrics in
MRI-guided cryoablations of renal cancer. The computer
generated ablation metrics were compared to metrics
calculated from manual segmentation of the tumor and the
ablation zone in 24 hr MR images of same cases. Based on
our experiments, the tool can provide accurate real-time
quantitative assessment of key ablation metrics.
