Minimally invasive freezing technique for precise tumor destruction
Cryoablation is an advanced interventional radiology technique that eliminates tumor cells by exposing them to extreme cold (below -20°C), followed by a controlled thawing phase. This freeze–thaw cycle causes thermal shock that leads to irreversible cell death. The procedure is performed percutaneously under image guidance (CT, ultrasound, or MRI), using cryoneedles activated by argon gas.
