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.

PRIMARY OBJECTIVE:

I. To evaluate the feasibility and safety of same day yttrium-90 radioembolization planning and treatment angiography.

SECONDARY OBJECTIVES:

I. To determine the patient costs associated with same diagnostic and treatment compared when compared to the standard two session methodology.

II. To determine the time required to perform the mandatory in-room technetium Tc-99m albumin aggregated (99mTc-MAA) imaging and the associated calculations for the lung shunt fraction and treatment 90Y-microsphere activity.

III. To determine the time for delivery of the therapy 90Y-microsphere radioactivity to the angiography suite after the therapy written directive by the authorized user.

OUTLINE:

The first 2 patients enrolled receive standard of care diagnostic and treatment during 2 visits for approximately 6 hours each within 2-4 weeks. During the first visit, patients undergo diagnostic angiography with embolization of potential hepatoenteric collaterals, receive technetium Tc-99m albumin aggregated as a surrogate to the therapy microspheres via catheter, and undergo planar imaging. During the second visit, patients undergo a second angiography and receive yttrium Y 90 resin microspheres via arterial microcatheter. Patients then undergo single-photon emission computed tomography-computed tomography (SPECT-CT) Bremsstrahlung imaging.

All subsequent patients enrolled undergo the same previously described diagnostic and treatment during 1 visit over about 8 hours.

After completion of study treatment, patients are followed up at 1, 3, and 6 months.

Inclusion Criteria:

• The ability to understand and sign informed consent
• Any candidate eligible for standard of care Y90 radioembolization for treatment of their primary or metastatic liver tumors

Exclusion Criteria:

• Patients with greater than 50% liver tumor burden
