Sufficient ablation margins are most important in reducing tumour recurrence. But how can one be certain in the assessment?

Side by side comparison of pre- and postoperative images has shown to produce poor outcomes. Evaluation of treatment success by assessment of ablation margins remains difficult and is subject to misjudgement in up to 44% of cases1. Hence, a crucial point in curative treatments of HCC is the evaluation of treatment success by utilizing specific software functionalites2,3.

AblaSure allows instantaneous, seamless and three-dimensional assessment of effective ablation margins against the previously created treatment plan.

Through integration into the existing Quality Ablation workflow AblaSure provides clinicians with accurate and immediate treatment assessment in their clinical practice4.

Ablation Margin Segmentation

  • Adjust segmentation with one-touch
  • Visualize in MPR- and Needle Eye View
  • Compare the effective ablation volume versus treatment plan/planned margin

Ablation Margin Histogram

  • Calculate the effective ablation volume compared to the segmented tumour and the selected safety margin
  • Identify potential mismatches between effective albation volume compared to the selected safety margin
  • Visualize the histogram in multiple millimeter increments

"The development of AblaSure as a margin assessment tool is yet another reason CT should be the preferred method over ultrasound for performing ablation interventions"
