CT-guided Radiofrequency Ablation (RFA)

How CT-guided Radiofrequency Ablation (RFA) is performed

This technique is mostly used for benign or low-grade lesions with clear imaging. If applicable, a puncture biopsy can be performed first for confirmation. During the procedure, the target is usually located under CT guidance. After establishing a percutaneous channel, a radiofrequency electrode is inserted, and the lesion is heated in planned stages to cause thermal coagulation necrosis. Vital signs and the distance to important tissues around the lesion are monitored during the process, and isolation or cooling protection is used when necessary. Postoperative observation includes pain and bleeding, and imaging is reviewed. The goal is to relieve symptoms and reduce lesion activity. The above is general health information, not medical advice; the specific plan is subject to specialist evaluation and hospital protocol.
