Microwave ablation : ウィキペディア英語版
Microwave ablation

Microwave Ablation (MWA) 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.
== History ==
The technique for thermal ablation in the lung by using radiofrequency ablation was first described in 1995 for use in animal lung tumor models and then in 2000 in humans.() Microwave ablation has emerged as a newer ablation modality and an addition to the arsenal of minimally invasive cancer care.
The purported benefits of microwave ablation over other heat-based modalities such as radiofrequency ablation and laser include a larger and faster volume of tissue heating with a given application. Unlike radiofrequency ablation, MWA does not rely on an electrical circuit allowing for multiple applicators to be used simultaneously.()
