Primary outcomePrimary: Treatment Response to Yttrium Y-90 Radioembolization — 2; 17; 17; 17 Participants
Summary
This phase II trial studies how well perflutren protein-type A microspheres and contrast-enhanced ultrasound work in improving response to radioembolization therapy in patients with liver cancer. Ultrasound contrast agents, such as perflutren protein-type A microspheres, use gas microbubbles to improve image quality. Using contrast-enhanced ultrasound imaging will "pop" these microbubbles and cause tumors to become more sensitive to radiation therapies.
