Positron-emission tomography for hepatocellular carcinoma: Current status and future prospects

Figure 1 2-Deoxy-2-(¹⁸F)fluoro-D-glucose positron-emission tomography-computed tomography detected tumor recurrence after intervention therapy in a 58-year-old male patient with hepatocellular carcinoma. A: Cross-sectional computed tomography (CT) image showing a large sheet of lipiodol deposition in the right lobe of live after HCC intervention therapy; B: Cross-sectional positron-emission tomography (PET-CT) fusion image showing increased ¹⁸F-FDG uptake in and around the area of lipiodol deposition (blue arrow); the size of the lesion was 5.8 × 13.3 cm; C: Cross-sectional PET image showing increased ¹⁸F-FDG uptake in the right lobe of the liver; D: Maximum intensity projection image showing increased ¹⁸F-FDG uptake in the right lobe of the liver. ¹⁸F-FDG: 2-deoxy-2-(¹⁸F)fluoro-D-glucose; CT: Computed tomography; PET: Positron-emission tomography.
