hatazawa at rcnp.osaka-u.ac.jpMy research is in the field of nuclear medicine, specializing in the development of integrated PET/MRI systems and other new neuroimaging technologies.
Information is transmitted between neurons through the synthesis, release and receptor binding of neurotransmitters in a synapse. It is possible to simultaneously measure the dynamics and receptor occupancy of labeled neurotransmitters and the corresponding change in blood flow by using electric excitation and an integrated PET/MRI system. Since developing our original integrated PET/MRI system, our research focuses on analyzing the intra-cerebral neurotransmission through observations of neurotransmitter, blood and energy metabolism behaviour. Such systems create a new fusion of morphological and functional imaging.
