CT-guided thermal ablation is a medical procedure that uses image guidance, usually using computed tomography (CT), to apply precise and controlled heat to a specific area of the body, often to treat tumors. During this procedure, a needle or probe is inserted into the target area under CT guidance. Once positioned, heat is applied to destroy the tumor cells without causing significant damage to surrounding tissue.

There are several forms of thermal ablation, including radiofrequency ablation (RFA) and microwave ablation, which use different techniques to generate heat. The choice of method depends on several factors, such as the location and size of the tumor, and the general health of the patient.

This procedure is often used to treat tumors in organs such as the liver, kidneys, and lungs, and is particularly useful for patients who may not be candidates for traditional surgical procedures. CT-guided thermal ablation offers advantages such as shorter recovery time, fewer complications and the ability to perform the procedure under local anesthesia.
