Comparison of pre-treatment and post-treatment tumor lesion images of a 46-year-old patient with hepatocellular carcinoma (HCC) and hepatitis B-related liver cirrhosis who underwent microwave ablation. Magnetic resonance images show a tumor with a small (15-mm) hyperintense nodule (a T2-weighted phase), intense arterial enhancement (b arterial phase), and enhancement recession (c portalvenous phase). Computed tomography images (d noncontrast-enhanced phase; e arterial phase; f portalvenous phase) obtained 2 days after treatment show no contrast enhancement inside or around the ablation zone
