A 66-year-old male patient with liver cirrhosis underwent radiofrequency ablation of left hepatic lobe focal lesion. A Axial T1 pre-contrast image showing hyperintense left hepatic lobe focal lesion after radio frequency ablation (open yellow arrow). B Suspected residual nodule seen at about 6 o’clock position in the arterial phase (open red arrow). C The subtracted images shows that that suspected residual nodule (open red arrow) is hyperintense denoting enhancing residual disease. The remaining portion of the nodule is hypointense denoting complete ablation. D Color-coded perfusion map shows enhancement of the residual nodule (open red arrow) with non-enhancing ablation zone (open yellow arrow)
