SPECT brain imaging of the dopaminergic system in Parkinsonism using and labeled agents

SPECT brain imaging of the dopaminergic system using and labeled agents, especially the simultaneous imaging of both pre‐ and postsynaptic neurons, promises to provide accurate diagnosis and differentiation of Parkinsonism. However, there are many degrading factors that affect the quality and quantitative accuracy of the SPECT images. These degrading factors limit the potential clinical applications of brain SPECT imaging. In this work, we …
