Figure 1 A 45-year-old man who underwent cryoablation for small hepatocellular carcinoma (HCC). (A, B) Axial and coronal magnetic resonance imaging (MRI) obtained during the arterial phase shows a nodule of approximately 1.1×1.5 cm (white arrow), located in liver segment VIII, abutting the diaphragm. (C) Cryoprobes were inserted into the tumor under computed tomography guidance. (D, E) MRI scanning 4 days after cryoablation of HCC. The HCC lesion was completely ablated, showing a hypovascular zone with a hypervascular inflammatory rim around the ablation zone (white arrow). (F) MRI scanning at 12 months after treatment shows that the ablated area had shrunk significantly (white arrow).
