Computed tomography (CT)-guided percutaneous ablation techniques are essential for treating malignancies across most organ systems. Radiofrequency, microwave, cryoablation, and irreversible electroporation offer diverse therapeutic options for various cancers.

Area of Science:

  • Interventional Radiology
  • Oncology
  • Medical Imaging

Context:

  • Applicator-based local ablations under computed tomography (CT) guidance are established clinical practices for treating malignant tumors.
  • Image-guided thermal and nonthermal ablation techniques are increasingly utilized for localized cancer treatment.

Purpose:

  • To describe the fundamental principles of various ablation technologies.
  • To outline the specific clinical applications for each ablation modality.
  • To review advancements in CT-guided interventions for improved precision and reduced radiation exposure.

Summary:

  • Radiofrequency ablation (RFA) and microwave ablation (MWA) are established hyperthermal techniques for liver, lung, and kidney tumors.
  • Cryoablation is primarily used for kidney cancer and musculoskeletal applications, while irreversible electroporation treats pancreatic and liver tumors nonthermally, preserving tissue structure.
