Figure 8. LR-TIV. Axial CT images from the hepatic arterial (A), portal venous (B), and delayed (C) phases following intravenous contrast administration and coronal image from the hepatic arterial phase (D). Enhancing soft tissue is present in the right and main portal veins (white arrow). Due to an associated parenchymal mass (black arrow) with arterial phase hyperenhancement (not shown) and “washout”, the most appropriate category for this finding is LR-TIV, likely due to HCC. CT: computed tomography; LI-RADS: Liver Imaging Reporting and Data System; HCC: hepatocellular carcinoma; LR-TIV: LI-RADS Tumor in Vein
