Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Antenna that radiates microwave energy to agitate water molecules and heat tissue to coagulative necrosis, giving fast, large, high-temperature zones less prone to heat-sink than RF. Typical procedural contexts include liver, kidney, lung, adrenal, bone, and soft-tissue tumor ablation.
What most clearly distinguishes it from similar devices?
Key distinctions
Microwave ablation delivers electromagnetic energy through an antenna to create thermal coagulation, distinguishing it from radiofrequency electrodes and cryoablation probes that use different energy mechanisms.
