This study looks at using special scans to check oxygen levels in tumors for people with liver cancer that has spread to a few places. It helps see how well a treatment called Y90 radioembolization works. In this treatment, tiny radioactive beads are put in a blood vessel to block blood flow to the tumor and give it radiation without hurting healthy parts. Two types of scans, BOLD MRI and FMISO PET, help measure the oxygen levels in the tumor. The study aims to see if these scans can predict how the tumor will respond to the treatment.

• Duration: Patients are followed for 90 days initially, then every 12 weeks.
• Visits Required: Scans before treatment and regular follow-ups.
• Eligibility: Patients must be over 18, with a specific type of liver cancer, and meet health criteria.
