Radiofrequency Ablation Guidance Using Computed Tomography (CT) for Lung Evaluation

What Is This Test Used For?

CT-guided radiofrequency ablation is typically performed to destroy small lung tumors, abnormal growths, or lesions that cannot be removed surgically. The CT scan provides real-time images to guide the placement of the ablation probe, ensuring precision and minimizing damage to surrounding healthy tissue.

How Is the Procedure Performed?

Before the procedure, you’ll receive sedation to relax you. A thin needle is inserted under CT guidance into the targeted lung area. Radiofrequency energy is then applied to the needle tip to heat and destroy the abnormal tissue. The CT scan continuously monitors the process to confirm the correct placement and effectiveness.

The CT scan evaluates the following during and after the ablation: the precise location and depth of the ablation zone, the extent of tissue destruction, and whether any surrounding healthy lung tissue was unintentionally affected. Post-procedure imaging helps confirm the procedure’s success and plan for follow-up care.

You may feel discomfort or pressure during the needle insertion, but sedation helps manage pain. Afterward, you might experience mild soreness or fatigue, but this is usually temporary. Follow your healthcare provider’s instructions for post-procedure care.

CT-guided radiofrequency ablation is critical for accurately targeting and treating lung lesions with minimal risk. Successful ablation reduces the need for more invasive procedures like surgery. However, follow-up imaging and monitoring are essential to ensure the procedure was effective and to detect any complications early.

Your doctor may recommend this test if you have a small lung lesion or tumor that cannot be treated with other methods, such as surgery or radiation. It is often used for patients with early-stage lung cancer or benign lesions that require precise destruction.
