Microwave ablation is a treatment that uses heat to treat liver tumors. An interventional radiologist makes a tiny incision in the skin to insert a special needle into the body. Using a live computed tomography (CT) scan or an ultrasound, the doctor guides the needle to the tumor. The interventional radiologist generates electromagnetic microwaves that can destroy the tumor.
The advantages of microwave ablation (removal of tissue) compared to radiofrequency ablation include a generation of higher temperatures and the ability to use multiple needles to better destroy larger tumors.
After the treatment, patients will follow up with their physician for several months. The treatment team will also order additional imaging scans to evaluate whether the microwave ablation was successful in destroying the tumor.
