Abstract：Brain molecular imaging plays an important role in investigations on the function of brain and mechanism of neural diseases. The dopaminergic receptor system is closely related with emotion, love, addiction, incentives, many diseases and disorders. Hereby, taking 18F-fallypride as an example of novel dopamine receptor D2/D3 probes visualizing the Dopamine D2/D3 receptors in striatal and extra-striatal areas, this paper reviews the trends of R&D(Research and Development) and clinical applications of 18F-fallypride, and investigates 18F-fallypride with 15 healthy volunteers’ brain imaging by using the self-innovated AMIC Ray-Scan 64 PET/CT. The result shows a homogeneous and symmetrical distribution of signal in striatal and extra-striatal areas, indicating that the 18F-fallypride, as well as Ray-Scan 64 PET/CT, has demonstrated an excellent performance in dopamine receptor imaging. Additionally, this paper also reviews the progress of clinical uses of 18F-ML-10, a molecular probe to visualize apoptosis. Besides, 10 patients with brain tumorsare investigated by 18F-ML-10-PET/CT imaging pre- and post- radiation with AMIC Ray-Scan 64 PET/CT, in order to evaluate the effect of treatments.
