Imaging reporter gene expression in living subjects with various imaging modalities is a rapidly accelerating area of research. Applications of these technologies to cancer research, gene therapy, and transgenic models are rapidly expanding. We report construction and testing of several triple fusion reporter genes compatible with bioluminescence,(More)
UNLABELLED Mitochondrial membrane potential (DeltaPsim)-dependent enhanced uptake of phosphonium salts, including (3)H-tetraphenylphosphonium ((3)H-TPP), in tumor cells, suggests the potential use of phosphonium salts as tracers for tumor imaging. In this study, we characterize the tumor accumulation of (3)H-TPP and compare it with (18)F-FDG in cell culture(More)
The preprocessing step of statistical parametric mapping (SPM) requires the procedure of spatia1 normalization that consists of applying the nonlinear deformations needed to force every particular PET scan to match a reference template. The purpose of this study is to asses the statistic influence of using 2 different templates (the standard SPMZ-PET(More)
