RFA- Radiofrequency Ablation of Liver and Kidney Tumours
Radiofrequency ablation (RFA) and microwave ablation (MWA) are treatments that use image guidance to place a needle through the skin into a liver tumor. ... In MWA, microwaves are created from the needle to create a small region of heat. The heat destroys the liver cancer cells.
Microwave Ablation is a form of thermal ablation used in interventional radiology to treat cancer. MWA uses electromagnetic waves in the microwave energy spectrum (300 MHz to 300 GHz) to produce tissue-heating effects. The oscillation of polar molecules produces frictional heating, ultimately generating tissue necrosis within solid tumors. It is generally used for the treatment and/or palliation of solid tumors in patients who are nonsurgical candidate.
