Metabolic positron emission tomography imaging of cancer: Pairing lipid metabolism with glycolysis

Figure 3 Corresponding ¹⁸F-fluorodeoxy-D-glucose positron emission tomography/computed tomography (A) and ¹⁸F-fluorocholine positron emission tomography/computed tomography (B) images of hepatocellular carcinoma obtained from the same patient on different days. The tumor is not at all evident on transaxial images of the liver from FDG PET/CT (A). Corresponding transaxial images of the liver from ¹⁸F-fluorocholine PET/CT (B) shows a 5-cm diameter circumscribed area of increased uptake in the left hepatic lobe (B) This tumor contained within the left hepatic lobe was histopathologically confirmed to be a well-differentiated HCC. FDG: ¹⁸F-fluorodeoxy-D-glucose; PET: Positron emission tomography; CT: Computed tomography; HCC: Hepatocellular carcinoma.
