Schematic diagram of CT image acquisition. The main tumor is located in the upper part of the right posterior lobe. (a) The tumor diameter before RFA is 44.2 mm. (b) The tumor diameter after RFA is 53.7 mm. (c) The tumor edge recurs 6 months after RFA. (d–g) The spatial relationship between the tumor before RFA and intrahepatic vessels (different color tissues in the figure: red: tumor; yellow: hepatic artery; green: portal vein; purple: hepatic vein and inferior vena cava). The postoperative CT diagram of the patient is shown in Figures 3 and 4.
