In this pilot study, 18 subjects with newly diagnosed HCC will be recruited. Each subject will undergo a 68Gallium-citrate PET/CT scan within 6 weeks of radiographic diagnosis. Foci of abnormal radiotracer uptake on these scans will be tabulated and compared to clinically-indicated morphologic imaging. The investigators expect that 68Gallium-citrate PET/CT will offer a sensitive functional imaging modality for identification of HCC lesions in the liver. The investigators intend to use the results of this preliminary study to form the basis for grant applications to extra-mural funding agencies. These subsequent grant applications will focus on further studies in the utility of 68Gallium-citrate PET/CT for HCC therapy monitoring and metastatic work-up.
