A hospital in Australia is using a new MRI technology that can eliminate certain tumors without a single incision.
No surgery required.
Doctors at Liverpool Hospital in Sydney have introduced the country's first dedicated MRI-guided cryoablation system, allowing specialists to destroy localized tumors by freezing them into what are essentially tiny iceballs inside the body.
The procedure works by inserting ultra-thin needles directly into a tumor while doctors track every movement in real time using high-resolution MRI imaging. Once in position, compressed argon gas rapidly cools the probe tip to an astonishing -180°C, freezing the tumor from the inside out.
The extreme cold ruptures cancer cells, cuts off their blood supply, and destroys the targeted tissue.
What makes the technology especially powerful is its precision. Because doctors can continuously monitor the growing iceball on MRI scans, they can ensure the tumor is destroyed while avoiding damage to nearby structures such as nerves, bones, the spinal cord, kidneys, or liver.
For many patients, the treatment could offer a far less invasive alternative to major surgery. Traditional procedures for tumors near the spine or other sensitive areas can require extensive operations, implanted hardware, lengthy hospital stays, and months of recovery. MRI-guided cryoablation can often be completed in a single day, with patients returning home just hours later.
Doctors say the technology could transform how certain cancers and painful tumor-related conditions are treated, marking a major step toward a future where highly targeted therapies replace many conventional surgical procedures.
