Thermal ablation: Targeted in situ tissue destruction via exposure to extreme high or low temperatures using nonionizing modalities
Thresholds for damage approximately > 50°C for heating and < -20°C for cooling
Depend on heat/cool rate and exposure time
Thermal dose models estimate tissue damage using tissue temperature history
Focused ultrasound surgery (FUS): Conformal heating of target tissue using highly focused acoustic energy
Generally delivered noninvasively using extracorporeal transducer array (1–2 MHz)
Acoustic coupling to patient and path to target
Damage small & requires multiple shots for conformal volume coverage
Interstitial ablative therapies: Image-guided percutaneous placement of treatment applicators for minimally invasive local heating/cooling
Radiofrequency ablation (RFA): Heating mediated by radiofrequency-induced current in conductive tissue
High current density induced near interstitial metal electrode attached to RF generator
Power ~ 200 W operating at 400-800 kHz
Joule (resistive) heating via ionic agitation
Grounding pad on skin disperses current density in tissue away from electrode
Electrode cooling employed to minimize conduction loss and generate larger lesions
Microwave ablation (MWA): Heating mediated by electromagnetic agitation of tissue water (dielectric heating)
Dielectric heating less effective in low water-content tissue (i.e., adipose)
MW generator attached to metal antenna
Power 10-200 W operating at 0.9-2.5 GHz
Interstitial cooled antenna for controlling lesion shape and size
External antenna can be used for noninvasive "focal" approach to MWA
Laser ablation (LA): Heating mediated via local tissue light absorption
Laser fibers deliver high-power density of light (800-1,064 nm)
Cooled applicators facilitate rapid, large lesion formation
Cryoablation: Freezing mediated by rapid cooling of metal probe
2 cool-thaw (< -40°C) cycles for biological effectiveness
Cooling: Rapid argon gas expansion (Joule-Thompson effect) or liquid nitrogen
Thaw: Passive or active (rapid helium gas expansion)
