| Outline of Final Research Achievements |
Signal simulations for the various tissue were conducted using theoretical equations of MRI signals. Good correlations were noted between signal simulation and O-17 phantom signal, and conversion method from MRI signal to O-17 concentration was determined. Based on the MRI scans of normal volunteers, scan method with FSE sequence was established, and development of algorithm for quantitative analysis of cerebral blood flow.
Manufacturing of O-17 oxygen was established, and inhalation apparatus of O-17 was designed. Smaller O-17 phantom was created, and MRI scans with animal MRI were performed. Good image contrast was obtained for marmosets with the administration of O-17 water.
