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.

Figure 2 11C-choline positron-emission tomography-computed tomography detected a tumor that was missed on conventional 2-deoxy-2-(18F)fluoro-D-glucose positron-emission tomography-computed tomography in a 58-year-old patient with hepatocellular carcinoma. A-D: 2-deoxy-2-(18F)fluoro-D-glucose positron-emission tomography-computed tomography (18F-FDG PET-CT) showed that there was no increased 18F-FDG uptake in the liver; E-H: 11C-choline (11C-CHOL) PET-CT showed focal increased 11C-CHOL uptake in the upper segment of the anterior lobe of the liver, and the size of the lesion was 1.2 × 1.3 cm (blue arrow in F and G). Pathological examination confirmed well-differentiated hepatocellular carcinoma. 18F-FDG: 2-deoxy-2-(18F)fluoro-D-glucose; CT: Computed tomography; PET: Positron-emission tomography; 11C-CHOL: 11C-choline.

Figure 3 Early dynamic 2-deoxy-2-(18F)fluoro-D-glucose positron-emission tomography-computed tomography detected a tumor that was missed on conventional 2-deoxy-2-(18F)fluoro-D-glucose positron-emission tomography-computed tomography in a 64-year-old patient with hepatocellular carcinoma. A-D: 2-deoxy-2-(18F)fluoro-D-glucose positron-emission tomography-computed tomography (18F-FDG PET-CT) showed that there was no increased 18F-FDG uptake in the lesion on conventional 18F-FDG PET-CT; E-H: Early dynamic 18F-FDG PET-CT showed focal 18F-FDG hyperperfusion in the upper segment of the anterior lobe of the liver, and the size of the lesion was 1.7 × 1.9 cm (blue arrow in F and G). 18F-FDG: 2-deoxy-2-(18F)fluoro-D-glucose; CT: Computed tomography; PET: Positron-emission tomography.
