Area of Science:

  • Oncology
  • Minimally Invasive Surgery
  • Medical Imaging

Background:

  • Percutaneous image-guided radiofrequency ablation (RFA) is a minimally invasive cancer treatment.
  • A significant risk of RFA is unintended thermal injury to adjacent healthy tissues.
  • Balancing tumor destruction with collateral tissue preservation is crucial for patient safety.

Purpose of the Study:

  • To evaluate the utility of remote thermistors in monitoring temperatures near collateral structures during tumor RFA.
  • To assess the safety of RFA when temperature-sensitive structures are in proximity to the target lesion.

Main Methods:

  • Utilized remote thermistors for real-time temperature monitoring during percutaneous RFA procedures.
  • Described four unique clinical cases involving tumor RFA near critical structures.

  • Focused on temperature measurements at locations adjacent to the ablation zone.

    • Main Results:

    • Demonstrated successful temperature monitoring using remote thermistors during tumor RFA.
    • Observed temperature fluctuations in collateral tissues, providing real-time safety data.
    • Highlighted the feasibility of using this technique in diverse clinical scenarios.

    Conclusions:

    • Remote thermometry is a valuable tool for increasing the safety of image-guided RFA.
    • This technique can help mitigate the risk of thermal damage to nearby normal tissues.
    • Remote thermometry enhances the safety profile of evolving minimally invasive procedures like RFA.
