No results posted yet for this study

Summary

Contrast-enhanced ultrasonography (CEUS)-CT/MRI fusion imaging substantially improved the visibility of small tumors that were inconspicuous on both US and US-CT/MRI fusion imaging, contributing to successful percutaneous radiofrequency ablation.

Conditions

  • Radiofrequency Ablation
  • Ultrasonography
  • Liver Tumors

Interventions

PROCEDURE

Percutaneous Radiofrequency Ablation

In brief, ablation was performed using a 200-W multichannel generator and a switching monopolar technique with separate clustered electrodes. Tumor targeting was done under the guidance of CEUS-CT/MRI FI, and the ablation procedure was monitored with US-FI. The ablation procedure was terminated when the operator expected to complete the ablation of the index tumor with a minimum 5-mm ablative margin on the US-FI images.
