概要

CT-assisted radiofrequency ablation (RFA) using real-time virtual sonography (RVS) was performed for 3 patients with hepatocellular carcinoma (HCC) undetectable with conventional sonography. Combined CTHA and CTAP DICOM image or dynamic CT/MRI image were used as RVS reference images. RFA was performed in the CT room. The tumor site was punctured under sonography together with RVS, and immediately, CT was performed. Ablation was conducted after confirming on CT and 3D images that the needle had been inserted into the tumor. The RFA needle was inserted into the tumor in all cases. This method allowed safe ablation with enough margin without complications. CT-assisted RFA using RVS is a safe and effective treatment for HCC undetectable with conventional sonography.
