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

Figure 1 Case 1. A: Positron emission tomography scan: the white arrow shows the area of multiple foci of fludeoxyglucose uptake in the treated area; B: Multi-phase magnetic resonance imaging scan: it shows no arterial enhancement in the same area during the arterial phase; C: Positron emission tomography scan: the arrow indicates an area of fludeoxyglucose uptake, indicating another residual tumor.
