Utility of positron emission tomography-computed tomography scan in detecting residual hepatocellular carcinoma post treatment: Series of case reports

Figure 3 Case 3. A: Positron emission tomography scan: the white arrow indicates a small focus of fludeoxyglucose uptake adjacent to the treatment zone showing absent metabolic activity; B: Multi-phase magnetic resonance imaging: the white arrow points to focal bleed at the periphery of the treatment zone post microwave ablation without evidence of any viable tumor during the arterial phase.
