Increased FDG uptake in 9x6 cm sized mass with exophytic extension at liver segment 6 (SUVmax: 5.11). Increased FDG uptake was also observed in the right hepatic vein, extending to the inferior vena cava (SUVmax: 4.56), consistent with malignant portal vein thrombosis.

Hepatic perfusion scintigraphy with MAA particles (185 MBq) delivered to the right hepatic artery showed increased perfusion of both primary mass and portal vein thrombosis. Glass microspheres loaded with 3.54 GBq ⁹⁰Y injected to the same region demonstrated a similar distribution with MAA scan. Post-treatment voxel-based dosimetry showed absorbed doses in the primary mass and the PVT as 300 Gy and 220 Gy, respectively.

¹⁸F-FDG PET/CT performed at 12 weeks after TARE showed complete metabolic response in PVT and the primary lesion in segment 6.
