This clinical trial studies the side effects and best way to perform yttrium Y-90
radioembolization in treating patients with liver cancer that has spread to other places in
the body (metastatic). Yttrium Y-90 radioembolization is a therapy that injects radioactive
microspheres directly into an artery that feeds liver tumors to cut off their blood supply.
Performing yttrium Y-90 radioembolization in a single session may make treatment faster,
minimize patient travel, and decrease the overall cost of the procedure.
