This pilot clinical trial studies positron emission tomography (PET)/computed tomography (CT) in finding beads after Yttrium-90 bead therapy in patients with primary liver cancer or cancer that has spread to the liver (metastatic) that can not be removed by surgery. Imaging procedures, such as PET/CT after Yttrium-90 bead therapy, may help see if the beads are present in the lung and compare the results with the pre-therapy imaging.
PRIMARY OBJECTIVES: I. To estimate the absolute difference in post-therapy Yttrium-90 microsphere hepatopulmonary shunt fraction and the pre-therapy Technetium-99m macroaggregated albumin hepatopulmonary shunt fraction in patients with unresectable primary hepatic malignancy and hepatic metastatic disease. SECONDARY OBJECTIVES: I. To quantify and compare the pre-therapy Technetium-99m macroaggregated albumin particle sizes and post-therapy Yttrium-90 microsphere sizes. OUTLINE: Patients receive routine pre-therapy Technetium-99m macroaggregated albumin. Patients then undergo routine radioembolization with Yttrium-90 microspheres. Within 36 hours after radioembolization, patients undergo PET/CT imaging. Available imaging, clinical, interventional and surgical follow-up data for 2 years after completion of enrollment in the study will be obtained.

Absolute difference in post-therapy Yttrium-90 microsphere and pre-therapy Technetium-99m macroaggregated albumin hepatopulmonary shunt fraction values
Non-parametric Wilcoxon signed rank testing will be used to compare the 99mTc MAA and 90Y microsphere shunt fractions. Alternatively, a natural log transformation of the hepatopulmonary shunt fractions may be used to normalize these data for subsequent parametric paired t-test analysis.
Time frame: Baseline to up to 36 hours after radioembolization
In vitro Technetium-99m macroaggregated albumin particle size and microsphere size for each patient
Descriptive statistical assessment of Technetium-99m macroaggregated albumin particle size and microsphere size for each patient (e.g., mean, median, standard deviation, distribution, etc.) will be performed.
Time frame: Baseline up to 24 months
