a–c. Example of a heat sink from the right hepatic vein in a 51-year-old woman with CRCLM. MRI performed pre-RF ablation during the portal venous phase of the gadolinium-enhanced axial image (a) reveals a 1.8 cm lesion (black arrow) adjacent to the right hepatic vein. MRI performed one-month post-RF ablation (b) shows that RF ablation was a technical success. On post-gadolinium imaging there is ablation right up to the hepatic vein (white arrow). Diffusion-weighted imaging performed two years later (c) shows an area of abnormal high signal intensity (black arrow) with corresponding abnormal enhancement post-gadolinium.
