Objective: We attempted to identify the locus of cerebral blood flow reduction to clarify the functional neuroanatomical basis of the first-episode schizophrenia. A secondary objective was to evaluate the diagnostic value a new analytical program, easy Z-score Imaging System (eZIS). Method: We performed single photon emission computed tomography (SPECT) with 99-Tc-ethyl cysteinate dimmer (^<99m>Tc-ECD) of the brains of patients with the first-episode schizophrenia (n=30) and normal controls (n=37) and evaluated the diagnostic value of brain perfusion SPECT using eZIS on patients with schizophrenia. Result: In comparison with normal controls, the patients with schizophrenia were found to have reduced blood flow in bilateral frontal and temporal areas. Conclusion: In our study, patients with the first-episode schizophrenia appeared to have significant bilateral fronto-temporal hypoperfusion. Demonstration of abnormality of frontal and temporal lobe blood flow may assist in the diagnosis of schizophrenia and determination of appropriate treatment for individuals with schizophrenia.
