Figure 1: Magnetic resonance imaging of hepatocellular carcinoma before and after microwave ablation: A1, hepatocellular carcinoma shows enhancement on contrast-enhanced magnetic resonance imaging before treatment; A2, The nonperfused volume is visible on contrast-enhanced magnetic resonance imaging 1 month after treatment; A3, the lesion size shrink and the nonperfused volume still is visible on contrast-enhanced magnetic resonance imaging 6 months after treatment
