Male patient 56 years old with chronic viral hepatitis C and HCC in segment VII diagnosed as HCC. He underwent RFA; follow-up MRI was done after 13 weeks after ablation revealed a high ADC value and no diffusion restriction in a non-viable ablated bed. The lesion showed a low signal at T1WI (a), a high signal at T2WI (b), it shows no contrast enhancement at DCE series “arterial (c), portal (d), delayed (e) phases”, and the lesion showed a low signal at DWI b value = 800 (f) and corresponding high signal at ADC mapping series (g, h) ADC = 2.1 × 10⁻³ mm²/s
