Abstract

Image-guided local ablation is used to treat selected primary and metastatic liver tumors. Contrast-enhanced CT or MRI is essential for assessing technical success, detecting residual or recurrent tumor, and identifying complications. This pictorial review summarizes typical early and follow-up appearances after thermal ablation and highlights findings that may mimic viable tumor. Accurate interpretation requires attention to enhancement rather than attenuation or signal intensity alone, the expected evolution of the ablation zone, and the distribution of peripheral enhancement.
