概要 | Background: Red blood cells (RBCs) labeled with single-photon emitters have been clinically used for blood-pool imaging. Although some PET tracers have been introduced for blood-pool imaging, they have not yet been widely used. The present study investigated the feasibility of labeling RBCs with F-18-2-deoxy-2-fluoro-D-glucose(F-18-FDG) for blood-pool imaging with PET.RBCs isolated from venous blood of rats were washed with glucose-free phosphate-buffered saline and labeled with F-18-FDG. To optimizelabeling efficiency, the effects of glucose deprivation time and incubation (labeling) time with F-18-FDG were investigated. Post-labeling stability was assessed by calculating the release fraction of radioactivity and identifying the chemical forms of F-18 in the released and intracellular components of F-18-FDG-labeled RBCs incubated in plasma. Just after intravenous injection of the optimized autologous F-18-FDG-labeled RBCs, dynamic PET scans were performed to evaluate in vivo imaging in normal rats and intraabdominal bleeding models (temporary and persistent bleeding).Results: The optimal durations of glucose deprivation and incubation (labeling) with F-18-FDG were 60 and 30 min, |
