47383 vs. 0600T for CT-guided percutaneous liver ablation. "The patient was placed on the CT scanner in the supine position. Initial CT images of the upper abdomen were obtained. Automated exposure control was utilized. The skin overlying the liver was prepped and draped in the standard sterile fashion. Under CT guidance three IRE ablation probes were advanced to the lesion in the caudate lobe. Once the three probes were positioned appropriately sagittal reconstructions were performed and ablation parameters were calculated. Ablation was performed using standard protocol and reverse polarity. Probes were removed. Two IRE probes were then advanced to the peripheral right lobe lesion and ablation was performed in the same manner. Probe were removed and follow-up CT scan was obtained showing expected postablation changes with no significant hemorrhage. IRE ablation was utilized due to the otherwise inaccessible lesion in the caudate lobe. IMPRESSION: Impression: CT-guided liver mass ablation x 2."
