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.
