| Research Abstract |
One of the aims was to analyze the sequential and spatial change of benzodiazepine receptor density, metabolism, neuronal integrity using molecular imaging such as SPECT and PET. To clarify the sequential change, we investigate the reconstruction and analyzing method for animal C-11 flumazenil using animal PET/SPECT/CT. We developed a new method for analyzing binding potential of C-11 flumazenil using rat model. Another aim was to investigate the relationship between effect of rehabilitation and neuronal integrity in patients with brain injury. First we studied the relationship between C-11 flumazenil PET findings and I-123 Iomazenil SPECT findings. Our study indicated that although IMZ SPECT has slightly lower contrast than FMZ PET, IMZ SPECT could detect loss of neuronal integrity as almost same as FMZ PET. Second, we investigate the relationship among metabolic change, loss of neuronal integrity and effect of rehabilitation. However, we could not find the relationship among those parameters.
