Comparison of percutaneous radiofrequency ablation and CyberKnife® for initial solitary hepatocellular carcinoma: A pilot study

Figure 3 Clinical example of good responder patient by CyberKnife^®. A 72-year old male with hepatitis C virus cirrhosis received CyberKnife^® therapy at a dose of 50 Gy in 5 fractions for hepatocellular carcinoma sized 28 mm in diameter in S6/7. A: Dynamic computed tomography (CT) scan in arterial phase before the treatment showed a hypervascular lesion in S6/7 (arrow); B: Axial view of radiation dose distribution; C: The lesion did not be distinguished on dynamic CT scan in arterial phase 12 mo after the treatment (arrow). This therapeutic response was described as a complete response.
