1. Volumetric functional MR imaging 3-4 weeks after initial intraarterial therapy can help distinguish between responders and nonresponders of unresectable hepatocellular carcinoma.
2. Volumetric functional MR response was found to improve overall survival compared to single-parameter responders and those with stable disease.
3. Agreement between anatomic response criteria and volumetric functional MR findings, as well as AFP response and imaging criteria, was low.
