58-year-old male with metastatic pancreatic neuroendocrine tumors (Child-Pugh score = 5/Class A, no ascites, no cirrhosis) in liver segments 4, 6, and 8 who had not received any previous systemic therapy. A-1 and A-2 are pre-intervention contrast-enhanced MR images at 20 and 70 sec post-contrast injection, respectively. B-1, -2 and C-1, -2 are pre- and post-radioembolization with Y-90 microspheres (TheraSpheres), respectively, of early (B-1, C-1) and late (B-2, C-2) arterial dual-phase CBCT images. Note the similarity of tumor conspicuity and perfusion between the pre- and post-radioembolization in the dual-phase CBCT images (B-1 to C-1 and B-2 to C-2). This indicates minimal embolization and permits retreatment if indicated.
