Highly metabolic thrombus of the portal vein: 18F fluorodeoxyglucose positron emission tomography/computer tomography demonstration and clinical significance in hepatocellular carcinoma

Figure 2 Contrast CT scan showing right lobe and caudate lobe mass and portal vein thrombus of the right branch in the same patient. During the arterial phase, the thrombus appears as an iso- to hypodense intraluminal area with dense linear enhancement (white arrows, A). A filling defect was detected in the right branch during the portal phases (white arrows, B). PET (black arrows, C) and PET/CT fused images (white arrows, D) reveal a highly metabolic thrombus in the left branch.
