Coincidence planar imaging for dynamic [18F]FDG uptake in nude mice with tumors and inflammation: correlated with histopathology and micro-autoradiography.

The Institute of Nuclear Energy Research of Taiwan has developed a dynamic coincidence detection device for positron emitted radiotracer pharmacodynamic study in small mice models. In this study, we set up an experimental paradigm by determining [fluorine-18]-2-deoxy-2-fluoro-D-glucose ([18F]FDG) dynamic uptake in tumors and inflammations in nude mice as the foundation for future applications in therapy development. Histopathology and micro-autoradiography of these tumors and inflammations were obtained for confirmation.
