Abstract:
The present invention concerns a positron emission tomography (PET) contrast agent or imaging tracer comprising a red blood cell (RBC) internally labeled with 2-deoxy-2-(18F)fluoro-D-glucose (FDG); a method of preparing RBCs of a human or non-human animal for PET, comprising labeling RBCs in vitro with FDG to produce FDG-labeled RBCs; a method for in vivo imaging of RBCs using PET, comprising: introducing RBCs internally labeled with FDG (FDG-RBCs) into the circulatory system of a human or non-human animal subject in vivo; and PET imaging the introduced FDG-RBCs in the subject; a composition useful for labeling RBCs, and a kit for labeling RBCs.
