Surveillance of HCC Patients after Liver RFA: Role of MRI with Hepatospecific Contrast versus Three-Phase CT Scan—Experience of High Volume Oncologic Institute
Figure 3
66-year-old woman with an arteriovenous shunt after RFA for HCC. (a) Arterial-phase CT scan at 3-month followup. Enhancing tissue close to the ablated area, incorrectly diagnosed as residual tumor. (b) Portal-phase CT scan at 3-month followup. Enhancing tissue close to the ablated area, incorrectly diagnosed as residual tumor. The lack of washout should have raised the suspicion of a benign finding. (c) Arterial-phase MR image at 3-month followup. Enhancing tissue close to the ablated area, incorrectly diagnosed as residual tumor. (d) Portal-phase MR image at 3-month followup. The lack of wash-out and the same parenchymal enhancement identify the lesion as benign.
